Easy Agile Podcast Ep.16 Enabling high performing agile teams with Adaptavist

"It was great chatting to Caitlin about the importance of the Team Retrospective in creating a high performing cross-functional team" - Chloe Hall

In this episode, I was joined by Caitlin Mackie - Content Marketing Coordinator at Easy Agile.

In this episode, we spoke about;

• Looking at the team retrospective as a tool for risk mitigation rather than just another agile ceremony
• The importance of doing the retrospective on a regular cycle
• Why you should celebrate the wins?
• Taking the action items from your team retrospective to your team sprint planning
• Timeboxing the retrospective
• Creating a psychologically safe environment for your team retrospective

I hope you enjoy today's episode as much as I did recording it.

Transcript

Chloe Hall:

Hi, everyone. Welcome to the Easy Agile Podcast. I'm Chloe, Marketing Coordinator at Easy Agile, and I'll be your host for today's episode. Before we begin, we'd like to acknowledge the traditional custodians of the land from which I am recording today, the Wodi Wodi people of the Dharawal Speaking nation and pay our respects to elders past, present, and emerging. We extend that same respect to all Aboriginal and to Strait Islander peoples who are tuning in today. So today, we have a bit of a different episode for you. I'm going to be talking with Easy Agile's very own Content Marketing Coordinator, Caitlin Mackie. Caitlin is the Product Owner* of our Brand and Conversions Team*. Now this team is a cross-functional team who have only been together for roughly six months. And within their first few months, as a team, mind you they also had two brand new employees, they worked on a company rebrand.

Chloe Hall:

A new team, a huge task, the possibility of the team being high performing was unlikely at this point in time. So, the team was too new to have already formed that trust, strong relationships, and psychological safety, but somehow they came together and managed to work together, creating a flow of continuous improvement and ship this rebrand. So, I've brought for you today Caitlin onto the podcast to discuss the team's secret for success. Welcome to the podcast, Caitlin.

Caitlin Mackie:

Thanks, Chloe. It's a bit different sitting on this side. I'm used to being in your shoes. I feel [inaudible 00:01:45]. I feel uncomfortable. [inaudible 00:01:46].

Chloe Hall:

Yeah. It's my first time hosting as well, so very strange. Isn't it? How are you feeling today?

Caitlin Mackie:

Yeah. Good. I'm excited. I'm excited to chat about our experience coming together as a cross-functional Agile team, and hopefully share some of the things that worked for us with our listeners.

Chloe Hall:

Yes, I know myself, and I'm sure our audience is very excited to hear what your team's secret to success was. Did you want to start off by telling us what was this big secret that really helped you work together as a team?

Caitlin Mackie:

That's a great question, Chloe. And that's a big question. I'm not sure if there's one key thing, I suppose, it is that ultimate secret source or that one thing that led to the success. I'm sure we all want to hear what that is. I would also love to know if there's just this one key ingredient, but I think something for us, and probably one of the most memorable things that really worked for us, and there was a lot for us to benefit from doing this, was actually doing our retrospectives. So that's probably the first thing that comes to mind when it comes to what led to our success.

Chloe Hall:

Okay. Yeah. In the beginning, why did you start doing the retrospectives?

Caitlin Mackie:

So, we were a new forming team, like you mentioned before, and we seen retrospectives as another Agile ceremony, and we saw other teams doing it and they were having a lot of success from it, so we became to jump on that bandwagon. And I think with being a new forming team, there are so many things that come into play. So, you're trying to figure each other out, how we all like to work and communicate with each other, all of that. And we were the first ever team dedicated to owning and improving our website. And we also knew it was likely that we'd be responsible for designing and launching a rebrand.

Caitlin Mackie:

So when you try and stitch all of that together, and then consider all those elements, we knew that we needed to reserve some time to be able to quickly iterate and call out what works and what doesn't. And what we did understand is that retrospectives are a great opportunity for the whole team to get together and uncover any problematic issues and have an open discussion aimed at really identifying room for improvement, or calling out what's working well, so we can continue to do that. So, I think retros allowed us to understand where we can have the most impact and how to be a really effective cross-functional Agile team.

Chloe Hall:

Wow. That is already so insightful. Yeah, it sounds like the retrospectives really helped you to gain that momentum into finding who your team is, becoming a well-working, high-performing cross-functional team. So, how often were you doing the retro? Were you doing this on a regular cycle, or was it just, "Okay. We have a problem. Some blockers have come up, we need to do a retro"?

Caitlin Mackie:

Yeah. I think initially retro, we kind of viewed retros as this thing where like, "Oh, we've done a few sprints now. We should probably do a retro and just reflect on how those few sprints went." It was kind of like this thing. It was always back of our mind. And we knew we needed to do it, but weren't really sure about the cadence and the way to go about it. So now, we do retros on a Friday morning, which is the last day of our weekly sprint. And then we jump into sprint planning after that. So after bio break as well, so let the team digest everything we talked about in retrospectives. And then we come into sprint planning with all the topics that we're discussed, and we will have a really nice, fresh perspective.

Chloe Hall:

Yeah.

Caitlin Mackie:

So, I think this works really well for us because everything is happening in a timely manner. We've just had a discussion about the best things that happened in the sprint or what worked really well, so you want to make sure you can practice the same behavior in the following, and vice versa for the improvements that you want to make. So, that list of action items that come out of a retrospective provide a really nice contact, context, sorry. And you have them all in mind during sprint planning.

Caitlin Mackie:

So for example, in the previous sprint, it might have come up that you underestimated your story points or there wasn't enough detail on your user stories. So, with each story or task that you are bringing into the sprint, you're then asking the question, is everyone happy with the level of detail? What are we missing? Or we've only story pointed this or two, is it more likely to be a five? So, everything is really fresh in your mind, and I definitely think that helps create momentum. When you've got the whole team working to figure out how you can be more effective with every sprint.

Chloe Hall:

That's such a great point that you just made Caitlin. And I love how going from doing the team retrospective, that you actually can take those action items and go into your sprint and put them into place straight away. It's really good. Otherwise, I feel like if you do the sprint retrospective on the Friday, and you're like, "Okay, these are our action items," get to Monday sprint planning and you're just thinking of the weekend. That [inaudible 00:07:20]

Caitlin Mackie:

Yeah, a hundred percent. Yeah. They're super fresher mind for everyone. So, it might not work for every team, but we find it works really well for us, because we're being really deliberate with how we approach sprint planning.

Chloe Hall:

Yeah. And then with that, I could see how doing the retro, how it could easily go over time, but then your team has sprint planning scheduled after. So, it's like you can't go over time. How have you managed to kind of time box that retrospective?

Caitlin Mackie:

Yeah, that's a really, really good question. And it is on purpose as well that they are scheduled closely together. Som as mentioned above, the discussion you've had in the retrospectives provides a nice momentum going to the sprint planning, but it does mean we have to watch the clock. And initially, this can be quite awkward, because you want to make sure that everyone feels heard and that everybody has the same opportunity to contribute. And I think this responsibility falls on the scrum master, or the product owner, or whoever's facilitating the retrospective to call it out and make sure everyone has the chance to be heard. You'll naturally have people tell the longer story or add a lot of extra context before getting to the point. And then you'll have others that will be a lot more direct. And I'm a lot like the latter. I struggle to get to the point, which doesn't work well when you're trying to time box a retrospective, right?

Chloe Hall:

And I can relate, same personality.

Caitlin Mackie:

Yes. So with this, I think it really comes down to communicating the expectation and the priority from the get go. With our team and with any team, you will want to figure out who you can perform really well and continually improve to exceed expectations and be better and learn and grow together. And I think if you all share that same mindset going into the retrospective and acknowledging that it's a safe

space to have difficult conversations. And as long as you're communicating with empathy, the team knows that it's never anything personal, and it's all in the best interest of the team. And that then helps the less direct communicators, like myself, address their point more concisely and really forces them to be more deliberate and succinct with their communication style.

Caitlin Mackie:

And that's really key to being able to stick to that time box, I think. And it does take practice, because it comes down to creating that psychological safety in your team. But once that's there, it's so much easier to call out when someone's going down a windy track, and bring the focus back and sort of say, "I hear you, what's the action item?" And just become a lot more deliberate.

Chloe Hall:

Wow. I couldn't even imagine like how hard it would be, with the personalities that yourself and I have, just trying to be so direct and get rid of all the fluffy stuff. I mean, look at what it's done to form such an amazing team that we have. So, you mentioned that aspect of psychological safety before. And how do you think being in a new cross-functional team... Only six months together, you had those new employees, do you think you were able to create a psychological safety space at any point?

Caitlin Mackie:

That's another fantastic question. And I feel like, honestly, it would be best to have a team discussion around this. It'd be interesting to hear everybody's perspectives around what contributes to that element of psychological safety and if everybody feels the same. So, I can't speak for the team, but my personal opinion on this or personal experience is that creating an environment of psychological safety really comes down to a mutual trust and respect. And at the end of the day, we all share the same goal. So, we all really, really respect what each other brings to the table and understand how all of these moving parts that we are working on individually all come together to achieve the goal. So, when we're having these open discussions in retros, or not even in retros, just communicating in general really, it's clear that we're asking questions in the best interest of the team and individual motives never come into play, or people aren't just offering their opinion when it's unwarranted or providing feedback, or being overly critical when they weren't asked to do so.

Caitlin Mackie:

So, none of those toxic behaviors happen, because we all respect that whatever piece of work is in question or the topic of discussion, the person owning that work, at the end of the day, is the expert. And we trust them, and we don't doubt each other for a second. And I think the other half of that is that we're also really lucky that if something doesn't go as we planned, we're all there to pick each other up and go again. So, this ties quite nicely into actually one of our values at Easy Agile is commit as a team. And this is all about acknowledging that we grow and succeed when we do it together, and to look after one another and engage with authenticity and courage. Som I may be biased, but I wholeheartedly believe that our team completely embraces that. And there's just such an admiration for what we all bring to the table, and I think that's really key to creating the psychological safety.

Chloe Hall:

I love that your team is really embracing our value, commit as a team and putting it into place, because that's what we're all about at Easy Agile, and it's just so great to see it as well. I think the other thing that

I wanted to address was... So again, during this cross functional team, and you've got design and dev, how do you think retros assisted you in allowing to work out what design and dev needed from each other?

Caitlin Mackie:

For sure. So, for some extra context for our listeners as well, so in our team, we've got two developers, Haley and David, and a designer, Matt and myself, who's in the marketing. So, we're very much a cross-functional little mini team. So, we all have the same goal and that same focus, but we also are all working on these little individual components that we then stitch together. So,, I think... We doing retros regularly. What we were able to identify was a really effective design and development cycle. So, we figured out a rhythm for what one another needed at certain points. For example, something we discovered really early was making sure that we didn't bring design and dev work into the same sprint. We needed to have a completely finished design file before dev starts working on it. And that might sound really obvious, but initially we thought, "Oh, well, if you have a half finished design file, dev can start working on that. And by the time that's done, the rest of the design file will be done."

Caitlin Mackie:

But what we failed to acknowledge is that by doing that, we weren't leaving enough capacity to iterate or address any issues or incorporate feedback on the first part of that design file, or if dev started working on it and design then gets told, "Oh, this part right here, it's not possible," so the designer is back working on the first part. And it just creates a lot of these roadblocks. So in retros, this came up and we were able to raise it and understand that what design needed from dev and what dev needed from design in order to make sure we weren't blockers for each other. And the action item out of the retro is that we all agreed that a design file had to be completely finished before dev picks up the work.

Chloe Hall:

I think it's so great that you were able to identify these blockers early on. Do you think like doing the retro on a weekly reoccurring basis was able to bring up those blockers quickly, or do you think it wouldn't have made a difference?

Caitlin Mackie:

No, definitely. I, a hundred percent, think that retros allowed us to address the blockers in a way more timely and effective manner. And we kind of touched on that before, but yeah, retros let you address the blockers, unpack them, understand why they're happening and what we need to do to make sure they don't happen again. So, for sure.

Chloe Hall:

Yeah. Yeah. I guess I want to talk a little bit now about the wins, the very exciting part of the retro, the part that we all love. So, how important do you think the wins are within the retro?

Caitlin Mackie:

So important. So, so, so important. It's like, when you achieve something epic as a team, you have to call it out. Celebrate all the wins, big, small. Some weeks will be better than others, but embrace that glass half full mentality. And there's always something to be proud of and celebrate, so call it out amongst

each other, share it with the whole company, publicly recognize it. Yeah, I think it's so important to embrace the wins. It just sort of creates a really positive atmosphere when you're in the team, makes everybody feel heard and recognized for their really positive contribution that they're making. And I think a big thing here as well is that if you've achieved something epic as a team, it's helpful for other teams to hear that as well, right? You figured out a cool new way to do something, share it. If it helped you as a team, it's most likely going to help another team.

Caitlin Mackie:

So I think celebrating the wins isn't even just reserved for work stuff either, right? If somebody's doing something amazing outside of work or hit a personal goal, get behind it.

Chloe Hall:

Yeah.

Caitlin Mackie:

To celebrate all the wins always.

Chloe Hall:

Yeah. And I think it's so good how you mentioned that it's vital to celebrate the wins of someone's personal life as well, because at the end of the day, we're all human beings. Yes,, we come to work, but we do have that personal element. And knowing what someone's like outside of work as well is an element to creating that psychological safe space and team bonding, which is so vital to having a good team at the end of the day. Yeah.

Caitlin Mackie:

Yeah, a hundred percent. Yeah, you hit the nail in the head with that. We talked about psychological safety before, and I definitely think incorporating that, acknowledging that, yeah, we are ourselves at work, but we also have a whole other life outside of that too, so just being mindful of that and just cheering each other on all the time. That's what we got to do, be each other's biggest cheerleaders.

Chloe Hall:

Yeah, exactly. That's the real key to success. Isn't it?

Caitlin Mackie:

Yeah, that's it. That's the key.

Chloe Hall:

So, you've been working really well as a new cross functional, high performing Agile team. How do you think... What is your future process for retros?

Caitlin Mackie:

We will for sure continue to do them weekly. It's part of the Agile manifesto, but we want to focus on responding to change, and I think retros really allow us to do that. It's beneficial and really valuable for

the team. And when you can set the team up for success, you're going to see that positive impact that has across the organization as a whole. So yeah, we've found a nice cadence and a rhythm that works for us. So, if it ain't broke, don't fix it.

Chloe Hall:

Yeah.

Caitlin Mackie:

Is that what they say? Is that the saying?

Chloe Hall:

I don't know. I think so, but let's just go with it. [inaudible 00:19:02], don't fix it.

Caitlin Mackie:

There we go. Yeah.

Chloe Hall:

You can quote Caitlin Mackie on that one.

Caitlin Mackie:

Quote me on that.

Chloe Hall:

Okay, Caitlin. Well, there's just one final thing that I want to address today. I thought end of the podcast, let's just have a little bit of fun, and we're going to do a little snippet of Caitlin's hot tip. So, for the audience listening, I want you to think of something that they can take away from this episode, an action item that they can start doing within their teams today. Take it away.

Caitlin Mackie:

Okay. Okay. All right. I would say always have the retrospective. Don't skip it. Even if there's minimal items to discuss, new things will always come up. And you have to regularly provide ways for the team to share their thoughts. And I'll leave you with, always promote positive dialogue and show value and appreciation for team ideas and each other. That's my-

Chloe Hall:

I love that.

Caitlin Mackie:

That's my hot tip.

Chloe Hall:

Thanks, Caitlin. Thanks for sharing. I really like how you said always promote positive dialogue. I think that is so great. Yeah. Well, thanks, Caitlin. Thanks for jumping on the podcast today and-

Caitlin Mackie:

Thanks, Chloe.

Chloe Hall:

Yeah. Sharing your team's experience with retrospectives and new cross functional team. It's been really nice hearing from you, and there's so much that our audience can take away from what you've shared with us today. And I hope that we've truly inspired everybody listening to get out there and implement the team retrospective on a regular basis. So, yeah, thank you.

Caitlin Mackie:

Thank you so much, Chloe. Thanks for having me. It was fun, fun to be on this side. And I hope everyone enjoys this episode.

Chloe Hall:

Thanks, Caitlin.

Caitlin Mackie:

Thanks. Bye.

"It was great to be able to have this conversation with Maysa and have her share her story. So many great takeaways." - Nick Muldoon

Join Nick Muldoon, Co-founder and Co-CEO of Easy Agile as he chats with Maysa Safadi, Engineering Manager at Easy Agile.

As a woman, growing up in the middle east and being passionate about pursuing a career in the world of tech, don’t exactly go hand in hand. Navigating her way through a very patriarchal society, Maysa talks about her career journey and how she got to where she is today.

Having the odds stacked against her, Maysa talks about challenging the status quo, the constant pressure to prove herself in a male-dominated industry, the importance of charting your own course and her hopes for the future of women in tech.

This is such an inspiring episode, we hope you enjoy it as much as we did.

Transcript

Nick Muldoon:

Hi, team. Nick Muldoon, co-founder co-CEO at Easy Agile, and I'm joined today by Maysa Safadi, who's an engineering manager here at Easy Agile. We'll get into Maysa's story and journey in just a little bit, but before we do, I just wanted to say a quick acknowledgement to the traditional custodians of the land from which we are recording and indeed broadcasting today, and they are the people of the Dharawal speaking country just south of Sydney and Australia. We pay our respects to elders past, present, and emerging, and extend that same respect to all Aboriginal Torres Strait Islander and First Nations people that are joining us and listening in today. Maysa, welcome. Thanks for joining us.

Maysa Safadi:

Thank you, Nick. Thank you for inviting me.

Nick Muldoon:

So, Maysa's on today. We're going to explore Maysa's journey on her career to this point, and I think one of the things that interests me in Maysa's journey is she's come from a fairly patriarchal society in the Middle East, and has overcome a lot of odds that some of her peers didn't overcome, and she's managed to come to Australia, start a family in Australia, has three beautiful children and is an engineering manager after spending so many years as a software engineer. So, Maysa, I'd love to learn a little bit about the early stages of your life and how you got into university.

Maysa Safadi:

I was born and raised in United Arab Emirates. I am one of nine. I have three brothers and five sisters. I'm the middle child actually. Dad and mom, they were very focused on really raising good healthy kids and more important is to educate all of their kids regardless if they are boys or girls. Started my education at schools there. When I graduated from high school, I end up getting enrolled in a college like what you call it here in Australia, TAFE.

Education in United Arab Emirates, it's not free. Being one of nine and having that aim and goal for my father to educate all of us. When it comes to education, it was two factors that play big part of it. Can dad afford sending me to that college or university? and then after I finish, will I be able to find a job in that field? One of my dream jobs, I remember growing up I wanted to be a civil engineer, and I remember my older brother, he's the second, was telling me it's good that you want to study civil engineering. Remember, you will not be able to find a job.

Nick Muldoon:

Tell me why.

Maysa Safadi:

United Arab Emirates, it's male dominated country. Civil engineering is a male dominated industry. If you are going to look for a job after a graduation, it is pretty much given to males and Emirati males first. So, kind of it needs to go very down in the queue before it gets to me, and to be realistic, sometimes you give up your dreams because you know that you are not going to have a chance later in life.

Nick Muldoon:

Oh, my gosh, this is demoralizing.

Maysa Safadi:

Unfortunately.

Nick Muldoon:

Okay,

Maysa Safadi:

So, the decision for me to get to engineering, it was, again, I couldn't really go to university because it was too expensive. My older sister had a friend who told her about this institute that they are teaching computers. When it came to mom and dad, they really told us, "Do whatever you want, study whatever you want, it is you who is going to basically study that field and you need to like it and you need to make sure that you can make the most of it." So, with that institute, it was reasonably okay for my dad to pay for my fees and they were teaching computers. I thought, "Yeah, all right, computers, it is in science field, right? I can't maybe study civil engineering, but I'm really very interested to know more about computers."

Nick Muldoon:

Similar, close enough.

Maysa Safadi:

Close enough. I end up getting enrolled and I remember the very first subject was fundamentals of computers or computer fundamentals, something like this, and I thought, "Yeah, all right, that is interesting," and I did really finish my education from there. After two years I ended up getting a diploma in computer science.

Nick Muldoon:

So, was this a unique situation for you or were most of your girlfriends from high school also going on to college?

Maysa Safadi:

It's unique actually, unique to my family. I'm not saying it's rare, you will find other families doing it, but it's not common. It is unique because, yes, most of the girls, if not all they go to school, it's compulsory in United Arab Emirate, but very small number of them pursue higher education. Pretty much girls, they end up finishing school and the very first chance to get married, they end up getting married and starting their own family. I remember-

Nick Muldoon:

And you've chosen a different path because-

Maysa Safadi:

Oh, yeah.

Nick Muldoon:

... yes, you have a family today obviously, but you established your career, you didn't finish school and get married.

Maysa Safadi:

I think I really give so much credit to mom and dad in that sense. They told us education is more important than starting a family or getting married. They said, "Finish your degree, finish your education, then get married." The other thing they said, "Do not even get married while you are studying because for sure you won't be able to finish it. Maybe because your husband wouldn't want you to finish it. Maybe you will become so busy with the kids and you will put it back." I remember actually so many times with my older sisters when someone, it's traditional marriage there, when some people come and propose to marry or to propose for their hands, my dad always used to say, "No, finish your education first."

Nick Muldoon:

So, this is interesting because I think your eldest was born when you went and actually continued education and got your master's, is that correct?

Maysa Safadi:

Yes. I got diploma in computer science. However, I always wanted a bachelor degree. I knew that there is more to it. I fell in love with computing but I wanted more, and always I had that perception in mind, "If I'm going to get a better opportunity, then I have to have a better certificate or education." So, I thought getting a bachelor degree is going to give me better chances. I was working in United Arab Emirates and saving money, and Wollongong University had a branch there in Dubai. So, I had my eyes on finishing my degree there. Eventually I end up enrolling at Wollongong University, Dubai campus, to get my bachelor degree in computer science.

Nick Muldoon:

So, just for folks that are listening along, Wollongong is the regional area of Australia where Maysa and I and many of our team live. So, University of Wollongong is the local Wollongong University that has a branch in Dubai.

Nick Muldoon:

So you were with University of Wollongong doing this bachelor degree, and how did you make the transition and move to Australia?

Maysa Safadi:

When I was studying at Wollongong University, Dubai campus, and was working at the same time to be able to pay the fees, I met my husband at work, and happened that he has a skilled migrant visa to come to Australia, coincident. So, I was thinking, "All right, he is going to go to Australia, he is a person that I do really see spending the rest of my life with. So, how about if I transfer my papers to Wollongong University here in Australia, finish my degree from here, while he gets the chance to live in the country, and then we can make our minds. 'Is it a place for us to continue our life here?' If not, it was a good experience. If good, that is another new experience and journey that we are going to take." So, we end up coming to Australia. I finished my degree from here.

Nick Muldoon:

What did you find when you arrived at Australia? How was it different from United Arab Emirates? How was it different for women? How was it different for women in engineering given what your brother had said about civil engineering in Dubai?

Maysa Safadi:

I had a culture shock when I came to Australia. Yes, I was in a country that.... male-dominated country, third world country, no opportunities for females, to a country where everything is so different. The way of living, the communication, the culture, everything was so different. When it comes to engineering, because I didn't really finish my degree in United Arab Emirate, so I didn't even get the chance to work in engineering though. However, knowing about the country and knowing about the way they take talents in, I knew I had slim chances. Now, coming to Australia and to finish my degree at the university, it was challenging. Someone from the Middle East, english is second language, being in computer degree where looking around me, "My god, where are the girls? I don't really see many of them around." And then, yeah, getting into that stereotype of industry or of a field where it is just only for males.

Nick Muldoon:

Yeah, so a bit of a culture shock coming across. I guess fast forward, you've spent a decade in software engineering and then progressing into engineering leadership. What was the change and how did you perceive the change going from a team member to a people leader?

Maysa Safadi:

I graduated from Wollongong University and I end up getting a job at Motorola as a graduate software engineer. In the whole team there was three females.

Nick Muldoon:

How big was the team?

Maysa Safadi:

How big was the team? It was around 20.

Nick Muldoon:

Okay.

Maysa Safadi:

Yep. There was the network team which had, I can't remember how many, but it was a different team. The team I was in, it is development team, and there was three girls in there, one of them another graduate that end up coming to the program and one that started a year before. Interesting, these two females, they are not in IT anymore. I really loved the problem solving, I really loved seeing the outcome of my work in people's hands because I was developing features for mobile phones. So, all was in mind then as an IC, how to become better at my work, how to learn more, how to prove myself to everyone that I'm capable as much as any other male in the team.

Nick Muldoon:

Do you think, Maysa, that that's something that you've had to do throughout your career to prove yourself?

Maysa Safadi:

Yes, yes. It's a tough industry. Really not seeing so many females it makes it hard because you look for role models that makes you think, "Oh, she made it. I can make it. If she's still in there, then I can learn from her." I missed all of that. I never had another mentor in my career or having even a female manager in all of the jobs I had before. So, always I was dealing with males, always I was trying to navigate my way to show them the different perspective I can bring. Even the subtle interactions I used to have with them giving me that, "You are not capable enough. You are not there yet. This is our territory. Why are you here?" All of these things, it does really, without you think about it, it does really sink your self-esteem and the self-worth when you are in industries like this. Yeah.

Nick Muldoon:

So, I'm conscious, you know are in this position now, you've kind of talked about you can't be what you can't see. If you can't see a woman that's a people leader and you're not reporting to one, then it's hard to see how you can become that. But, here you are, you have become that, and for our team here, you are one of the women leaders in the company, which is fantastic. So, I guess, what are the sorts of activities that you are undertaking to try and be present and be visible that you can be a woman people leader in the engineering field. I think it was earlier last month perhaps that you were at WomenHack in Sydney.

Maysa Safadi:

Yes, I've been-

Nick Muldoon:

What's WomenHack?

Maysa Safadi:

Okay. WomenHack, it is organization to bring diverse talented women intake together, to support them, to educate them, and not just only that, to try to connect them with other companies that they appreciate diversity and inclusion, and basically try to recruit... Pretty much, it is finding opportunities for women in tech, in companies that they do value the diversity.

Nick Muldoon:

Okay. So, I think it's interesting, I see these parallels here between your mom and dad that kind of went out on a limb and extended themselves financially to get six girls through a college and university education in the Middle East, and they were doing something that was perhaps fairly progressive at the time. You said it wasn't common. It sounds like WomenHack is bringing together more progressive companies these days, that are creating opportunities for women to get into leadership or even to accelerate their careers.

Maysa Safadi:

Yes, it is so pleasing to see the change that has happened over the years. When I reflect back in 2000, when I graduated and end up working in IT, and all of the behaviors, there was no knowledge or there was no awareness how much diversity is important, and they were not even aware that really females are really quitting the field or not that many females enrolls in the first place in degrees like computing or engineering. Even education through the school, no awareness was there. Then you see now the progress that is happening, more awareness is during school. Universities, they are trying to make the degrees or the fields more inviting for females and diversity. They are trying to bridge the gaps. So, many companies that are taking action to make it easier for females to be in the field and to progress in the field.

So, WomenHack, there are so many other groups like Women in Tech, there are so many companies that are allies to females in tech as well, where they are trying to really support and make their voice heard by other companies. Is as well all of the research and the science, are really proving that having diversity in teams, it is going to be more beneficial for the companies, for the teams, to have more engaging teams having these differences. So, yeah, there is a lot of awareness happening at the moment, and so many companies are trying to do something about it. I wish if that was early on.

Nick Muldoon:

Earlier in your career.

Maysa Safadi:

Earlier in my career, yes. So, many times I felt so isolated. So many times I was sitting back and saying, "Is it worth the fight?" Why do I have to work always twice as hard, to just only prove that I'm capable? Why does it have to be this way? Why I'm not equal?" That what actually made me change my career from IC to people leader. I didn't want to put other females... Being people leader wasn't just only for females, it was for me to voice, to be able to help pretty much. People leader to be able to help anyone in the field regardless if they are males or females. Moreso is to lead by example, is to be a role model for others, is to show others that if I can make it, then definitely you can as well, is to provide the support, it's to build that trust.

Nick Muldoon:

So, how can we, as an industry, I guess, how do we change... I'm reflecting on Iran at the moment, and the activities that have taken place over the last 60 days in particular, but really just more media coverage for hundreds of years of oppression of women. What do you hope, you being a people leader, a woman that's come from the Middle East, what do you hope for these young women and girls in our Iran over their trajectory? If we're still making a journey here in Australia, in a male dominated industry, what sort of hope do you have over the 20 years from here to 2040, for these women that are in the Middle East today and still haven't found a progressive society?

Maysa Safadi:

Politics. It's the game of power. Really hoping is the awareness to get there for these females in locked countries to know that there are better opportunities for them. They need to be stronger, they need to support each other, they need to empower each other. As much as it is easy said, it's not that easy done. However, all of that frustration that is built in them, it is surfacing from time to time. I'm really hoping for Iranian women, not just only Iranians, I'm really hoping for every woman in the world, regardless if it is a third world country or even if it is advanced country like Australia, is to always feel that they are worthy, is always to feel that they can have a voice, they can be part of life, and they are doing meaningful things.

Now, if they are raised in a way that always being told you are second, always being told you role only to get married and raise family, they will believe it themselves. So, it needs to come from women like us, leading by example, being role models, sending the awareness. Really media, we need to use the media very well so we can get to these people who are really locked in their countries now thinking that this is normal. It a lot of work needs to happen.

Nick Muldoon:

Well, that's an interesting observation. It is normalized for them, isn't it? So, look, reflecting on my own upbringing, I remember that my parents would always say you can achieve anything you put your mind to, but I could open up the newspaper, I could look on TV and I could see a host of people that were people that look like me, that is white males that were Australian, that were successful in business, and so I believed that I could do and be whatever I wanted to do and be. So, I guess, how do we get this message out? How do we tell your story more broadly to get this message out? That you can do whatever you put your mind to, you can achieve whatever you hope to achieve. There's something interesting for me to reflect on about the media piece that you're talking about.

Maysa Safadi:

Yeah, and I think the countries that they are advanced, the countries that they are really recognizing women more and more, they are more responsible in sending that awareness. They have to do more. It is basically, yeah, media, it is such an important thing. This is what people read everyday or watch everyday.

Nick Muldoon:

I guess, I'm conscious, like we're talking about half a world away in the Middle East, but you're actually involved in a community group here at home. What's that group that you're involved in and how's that helping women?

Maysa Safadi:

Yeah, I'm a board member for organization called Women Illawarra. It is run by women, for women. Basically this organization is to help women in domestic violence, it's basically to set them in the right path. It gives them services and it does educate them and even help them with the counseling, with legal support so they can get out of these situations. Make them believe that they can be part of this society, that they are important voice in the society, in the community, and they can really contribute and make an impact. So, by providing this education and this support, it is empowering these women to take matters their hand, and again, to really set the path for their own life and their own success. They need to take control back again, and yeah, even help their kids see their moms that they are really doing the right thing.

Nick Muldoon:

It's this interesting thread that comes through in your entire life story and your journey, that mom and dad wanted you to have an education so that you were empowered to chart your own course in life-

Maysa Safadi:

Yes.

Nick Muldoon:

... and here you are today, giving back to other women, trying to help them get an education and feel empowered so that they can chart their own course in life. I think that's fantastic. Thank you, Maysa.

Maysa Safadi:

Thank you.

Nick Muldoon:

What is your hope for women over the next 10 years? Because it sounds like we're on a trajectory, we're making progress in some countries, we're not making as much progress in other countries. What's your hope for 2030? What does it look like?

Maysa Safadi:

My hope for 2030, or my hope for... I really hope it is even five years, less than 10 years. My hope for 10 years is not to have conversations about how to reduce the gap between males and females, because by the 10 years time, that should be the way everyone operates. My hope in 10 years time is to have equal opportunities for anyone regardless what's their gender, background, language they speak, physical abilities, it needs to be equal, it needs to.... Equity, it is such an important thing. Giving exposure to the same opportunity, it is so important regardless what's your abilities. Stereotyping, I need that to get totally erased from the world.

We are all a human, we did not really choose where we born, who our parents are, what our upbringing, what our financial situation, it wasn't our choice, why do we have to get penalized for it? We have responsibility toward the world to help everyone. We are social people, we really thrive when we have good connections and good bonds, we really need to tap into the things that makes us better. So, we have so many talents that we can use it to the benefits of the world. I know countries always going to have fights and politics, that everyone is looking for the power, that's not going to disappear. But us, as people part of this world, we really need to try to uplift and upskill everyone around us. I really hope for the females in all of the other countries to know that they are worth it, to know that they are as good as anyone else. They have the power, they don't realize how much strength and power they have. So, it comes from self-belief. Believe in yourself, and you will be surprised how much you will be able to achieve.

Nick Muldoon:

There you go. Believe in yourself and you'll be surprised with how much you are able to achieve. Maysa Safadi thank you so much for your time. Really appreciate it.

Maysa Safadi:

Thank you so much Nick. Thank you everyone.

Jared Kells:

Welcome everybody to the Easy Agile podcast. My name's Jared Kells, and I'm a developer here at Easy Agile. Before we begin, Easy Agile would like to acknowledge the traditional custodians of the land from which we broadcast today, the Wodiwodi people of the Dharawal nation, and pay our respects to elders past, present and emerging, and extend that same respect to any aboriginal people listening with us today.

Jared Kells:

So today's podcast is a bit of a technical one. It says on my run sheet here that we're here to talk about some hot topics for engineers in the IT sector. How exciting that we've got a couple of primarily front end engineers and Angad and I are going to share some front end technical stuff and Jess and Jordan are going to be talking a bit about observability. So we'll start by introductions. So I'll pass it over to Jess.

Jess Belliveau:

Cool. Thanks Jared. Thanks for having me one as well. So yeah, my name's Jess Belliveau. I work for Apptio as an infrastructure engineer. Yeah, Jordan?

Jordan Simonovski:

I'm Jordan Simonovski. I work as a systems engineer in the observability team at Atlassian. I'm a bit of a jack of all trades, tech wise. But yeah, working on building out some pretty beefy systems to handle all of our data at Atlassian at the moment. So, that's fun.

Angad Sethi:

Hello everyone. I'm Angad. I'm working for Easy Agile as a software dev. Nothing fancy like you guys.

Jared Kells:

Nothing fancy!

Jess Belliveau:

Don't sell yourself short.

Jared Kells:

Yeah, I'll say. Yeah, so my name's Jared, and yeah, senior developer at Easy Agile, working on our apps. So mainly, I work on programs and road maps. And yeah, they're front end JavaScript heavy apps. So that's where our experience is. I've heard about this thing called observability, which I think is just logs and stuff, right?

Jess Belliveau:

Yeah, yeah. That's it, we'll wrap up!

Jared Kells:

Podcast over! Tell us about observability.

Jess Belliveau:

Yeah okay, I'll, yeah. Well, I thought first I'd do a little thing of why observability, why we talk about this and sort of for people listening, how we got here. We had a little chat before we started recording to try and feel out something that might interest a broader audience that maybe people don't know a lot about. And there's a lot of movements in the broad IT scope, I guess, that you could talk about. There's so many different things now that are just blowing up. Observability is something that's been a hot topic for a couple of years now. And it's something that's a core part of my job and Jordan's job as well. So it's something easy for us to talk about and it's something that you can give an introduction to without getting too technical. So we don't want to get down. This is something that you can go really deep into the weeds, so we picked it as something that hopefully we can explain to you both at a level that might interest the people at home listening as well.

Jess Belliveau:

Jordan and I figured out these four bullet points that we wanted to cover, and maybe I can do the little overview of that, and then I can make Jordan cover the first bullet point, just throw him straight under the bus.

Jordan Simonovski:

Okay!

Jess Belliveau:

So we thought we'd try and describe to you, first of all, what is observability. Because that's a pretty, the term doesn't give you much of what it is. It gives you a little hint, but it'll be good to base line set what are we talking about when we say what is observability. And then why would a development team want observability? Why would a company want observability? Sort of high level, what sort of benefits you get out of it and who may need it, which is a big thing. You can get caught up in these industry hot buzz words and commit to stuff that you might not need, or that sort of stuff.

Jared Kells:

Yep.

Jordan Simonovski:

Yep.

Jess Belliveau:

We thought we'd talk about some easy wins that you get with observability. So some of the real basic stuff you can try and get, and what advantages you get from it. And then we just thought because we're no going to try and get too deep, we could just give a few pointers to some websites and some YouTube talks for further reading that people want to do, and go from there. So yeah, Jordan you want to-

Jared Kells:

Sounds good.

Jess Belliveau:

Yeah. I hopefully, hopefully. We'll see how this goes! And I guess if you guys have questions as well, that's something we should, if there's stuff that you think we don't cover or that you want to know more, ask away.

Jordan Simonovski:

I guess to start with observability, it's a topic I get really excited about, because as someone that's been involved in the dev ops and SRE space for so long, observability's come along and promises to close the loop or close a feedback loop on software delivery. And it feels like it's something we don't really have at the moment. And I get that observability maybe sounds new and shiny, but I think the term itself exists to maybe differentiate itself from what's currently out there. A lot of us working in tech know about monitoring and the loading and things like that. And I think they serve their own purpose and they're not in any way obsolete either. Things like traditional monitoring tools. But observability's come along as a way to understand, I think, the overwhelmingly complex systems that we're building at the moment. A lot of companies are probably moving towards some kind of complicated distributed systems architecture, microservices, other buzz words.

Jordan Simonovski:

But even for things like a traditional kind of monolith. Observability really serves to help us ask new questions from our systems. So the way it tends to get explained is monitoring exits for our known unknowns. With seniority comes the ability to predict, almost, in what way your systems will fail. So you'll know. The longer you're in the industry, you know this, like a Java server fails in x, y, z amount of ways, so we should probably monitor our JVM heap, or whatever it is.

Jared Kells:

I was going to say that!

Jordan Simonovski:

I'll try not to get too much into-

Jared Kells:

Runs out of memory!

Jordan Simonovski:

Yeah. So that's something that you're expecting to fail at some point. And that's something that you can consider a known unknown. But then, the promise of observability is that we should be shipping enough data to be able to ask new questions. So the way it tends to get talked about, you see, it's an unknown unknown of our system, that we want to find out about and ask new questions from. And that's where I think observability gets introduced, to answer these questions. Is that a good enough answer? You want me to go any further into detail about this stuff? I can talk all day about this.

Jared Kells:

Is it like a [crosstalk 00:08:05]. So just to repeat it back to you, see if I've understood. Is it kind of like if I've got a, traditionally with a Java app, I might log memories. It's because I know JVM's run out of memory and that's a thing that I monitor, but observability is more broad, like going almost over the top with what you monitor and log so that you can-

Jordan Simonovski:

Yeah. And I wouldn't necessarily say it's going over the top. I think it's maybe adding a bit more context to your data. So if any of you have worked with traces before, observability is very similar to the way traces work and just builds on top of the premise of traces, I guess. So you're creating these events, and these events are different transactions that could be happening in your applications, usually submitting some kind of request. And with that request, you can add a whole bunch of context to it. You can add which server this might be running on, which time zone. All of these additional and all the exciters. You can throw in user agency into there if you want to. The idea of observability is that you're not necessarily constrained by high cardinality data. High cardinality data being data sets that can change quite largely, in terms of the kinds of data they represent, or the combinations of data sets that you could have.

Jordan Simonovski:

So if you want shipping metrics on something, on a per user basis and you want to look at how different users are affected by things, that would be considered a high cardinality metric. And a lot of the time it's not something that traditional monitoring companies or metric providers can really give you as a service. That's where you'll start paying insanely huge bills on things like Datadog or whatever it is, because they're now being considered new metrics. Whereas observability, we try and store our data and query it in a way that we can store pretty vast data sets and say, "Cool. We have errors coming from these kinds of users." And you can start to build up correlations on certain things there. You can find out that users from a particular time zone or a particular device would only be experiencing that error. And from there, you can start building up, I think, better ways of understanding how a particular change might have broken things. Or some particular edge cases that you otherwise couldn't pick up on with something like CPU or memory monitoring.

Angad Sethi:

Would it be fair to say-

Jared Kells:

Yeah. It's [crosstalk 00:11:02].

Angad Sethi:

Oh, sorry Jared.

Jared Kells:

No you can-

Angad Sethi:

Would it be fair to say that, so, observability is basically a set of principles or a way to find the unknown unknowns?

Jordan Simonovski:

Yeah.

Angad Sethi:

Oh.

Jess Belliveau:

And better equip you to find, one of the things I find is a lot of people think, you get caught up in thinking observability is a thing that you can deploy and have and tick a box, but I like your choice of word of it being a set of principles or best practices. It's sort of giving you some guidance around these, having good logging coming out of your application. So structured logs. So you're always getting the same log format that you can look at. Tracing, which Jordan talked a little bit about. So giving you that ability to follow how a user is interacting with all the different microservices and possibly seeing where things are going wrong, and metrics as well. So the good thing with metrics is we're turning things a bit around and trying to make an application, instead of doing, and I don't want to get too technical, black box monitoring, where we're on the outside, trying to peer in with probes and checks like that. But the idea with metrics is the application is actually emitting these metrics to inform us what state it is in, thereby making it more observable.

Jess Belliveau:

Yeah, I like your choice of words there, Angad, that it's like these practices, this sort of guide of where to go, which probably leads into this next point of why would a team want to implement it. If you want to start again, Jordan?

Jordan Simonovski:

Yeah, I can start. And I'll give you a bit more time to speak as well, Jess in this one. I won't rant as much.

Jess Belliveau:

Oh, I didn't sign up for that!

Jordan Simonovski:

I think why teams would want it is because, it really depends on your organization and, I guess, the size of the teams you're working in. Most of the time, I would probably say you don't want to build observability yourself in house. It is something that you can, observability capabilities themselves, you won't achieve it just by buying a thing, like you can't buy dev ops, you can't buy Agile, you can't buy observability either.

Jared Kells:

Hang on, hang on. It says on my run sheet to promote Easy Agile, so that sounds like a good segue-

Jess Belliveau:

Unless you want to buy it. If you do want to buy Agile, the [crosstalk 00:13:55] in the marketplace.

Jared Kells:

Yeah, sorry, sorry, yeah! Go on.

Jordan Simonovski:

You can buy tools that make your life a lot easier, and there are a lot of things out there already which do stuff for people and do surface really interesting data that people might want to look at. I think there are a couple of start ups like LightStep and Honeycomb, which give you a really intuitive way of understanding your data in production. But why you would need this kind of stuff is that you want to know the state of your systems at any given point in time, and to build, I guess, good operational hygiene and good production excellence, I guess as Liz Fong-Jones would put it, is you need to be able to close that feedback loop. We have a whole bunch of tools already. So we have CICD systems in place. We have feature flags now, which help us, I guess, decouple deployments from releases. You can deploy code without actually releasing code, and you can actually give that power to your PM's now if you want to, with feature flags, which is great.

Jordan Simonovski:

But what you can also do now is completely close this loop, and as you're deploying an application, you can say, "I want to canary this deployment. I want to deploy this to 10% of my users, maybe users who are opted in for Beta releases or something of our application, and you can actually look at how that's performing before you release it to a wider audience. So it does make deployments a lot safer. It does give you a better understanding of how you're affecting users as well. And there are a whole bunch of tools that you can use to determine this stuff as well. So if you're looking at how a lot of companies are doing SRE at the moment, or understanding what reliable looks like for their applications, you have things like SLO's in place as well. And SLO's-

Jared Kells:

What's an SLO?

Jordan Simonovski:

They're all tied to user experiences. So you're saying, "Can my user perform this particular interaction?" And if you can effectively measure that and know how users are being affected by the changes you're making, you can easily make decisions around whether or not you continue shipping features or if you drop everything and work on reliability to make sure your users aren't affected. So it's this very user centric approach to doing things. I think in terms of closing the loop, observability gives us that data to say, "Yes, this is how users are being affected. This is how, I guess the 99th percentile of our users are fine, but we have 1% who are having adverse issues with our application." And you can really pinpoint stuff from there and say, "Cool. Users with this particular browser or this particular, or where we've deployed this app to," let's say if you have a global deployment of some kind, you've deployed to an island first, because you don't really care what happens to them. You can say, "Oh, we've actually broken stuff for them." And you can roll it back before you impact 100% of your users.

Jared Kells:

Yeah. I liked what you said about the test. I forgot the acronym, but actually testing the end user behavior. That's kind of exciting to me, because we have all these metrics that are a bit useless. They're cool, "Oh, it's using 1% CPU like it always is, now I don't really care," but can a user open up the app and drag an issue around? It's like-

Jess Belliveau:

Yeah, that's a really great example, right?

Jared Kells:

That's what I really care about.

Jess Belliveau:

The 1% CPU thing, you could look at a CPU usage graph and see a deployment, and the CPU usage doesn't change. Is everything healthy or not? You don't know, whereas if you're getting that deeper level info of the user interactions, you could be using 1% CPU to serve HTTP500 errors to the 80% of the customer base, sort of thing.

Angad Sethi:

How do you do that? The SLO's bit, how do you know a user can log in and drag an issue?

Jordan Simonovski:

Yeah. I think that would come with good instrumenting-

Angad Sethi:

Good question?

Jordan Simonovski:

Yeah, it comes down to actually keeping observability in mind when you are developing new features, the same way you would think about logging a particular thing in your code as you're writing, or writing test for your code, as you're writing code as well. You want to think about how you can instrument something and how you can understand how this particular feature is working in production. Because I think as a lot of Agile and dev ops principles are telling us now is that we do want our applications in production. And as developers, our responsibilities don't end when we deploy something. Our responsibility as a developer ends when we've provided value to the business. And you need a way of understanding that you're actually doing that. And that's where, I guess, you do nee do think about observability with a lot of this stuff, and actually measuring your success metrics. So if you do know that your application is successful if your user can log in and drag stuff around, then that's exactly what you want to measure.

Jared Kells:

I think that we have to build-

Jordan Simonovski:

Yeah?

Jared Kells:

Oh, sorry Jordan.

Jordan Simonovski:

No, you go.

Jared Kells:

I was just going to say we have to build our apps with integration testing in mind already. So doing browser based tests around new features. So it would be about building features with that and the same thing in mind but for testing and production.

Jess Belliveau:

Yeah and the actual how, the actual writing code part, there's this really great project, the open telemetry project, which provides all these sort of API's and SDK's that developers can consume, and it's vendor agnostic. So when you talk about the how, like, "How do I do this? How do I instrument things?" Or, "How do I emit metrics?" They provide all these helpful libraries and includes that you can have, because the last thing you want to do is have to roll this custom solution, because you're then just adding to your technical debt. You're trying to make things easier, but you're then relying on, "Well I need to keep Jared Kells employed, because he wrote our log in engine and no one else knows how it works.

Jess Belliveau:

And then the other thing that comes to mind with something like open telemetry as well, and we talked a bit about Datadog. So Datadog is a SaaS vendor that specializes in observability. And you would push your metrics and your logs and your traces to them and they give you a UI to display. If you choose something that's vendor agnostic, let's just use the example of Easy Agile. Let's say they start Datadog and then in six months time, we don't want to use Datadog anymore, we want to use SignalFx or whatever the Splunk one is now.

Jordan Simonovski:

I think NorthX.

Jess Belliveau:

Yeah. You can change your end point, push your same metrics and all that sort of stuff, maybe with a few little tweaks, but the idea is you don't want to tie in to a single thing.

Jordan Simonovski:

Your data structures remain the same.

Jess Belliveau:

Yeah. So that you could almost do it seamlessly without the developers knowing. There's even companies in the past that I think have pushed to multiple vendors. So you could be consuming vendor A and then you want to do a proof of concept with vendor B to see what the experience is like and you just push your data there as well.

Jared Kells:

Yeah. I think our coupling to Datadog will be I all the dashboards and stuff that we've made. It's not so much the data.

Jess Belliveau:

Yeah. That's sort of the big up sell, right. It's how you interact. That's where they want to get their hooks in, is making it easier for you to interpret that data and manipulate it to meet your needs and that sort of stuff.

Jordan Simonovski:

Observability suggests dashboards, right?

Jess Belliveau:

Yeah, perhaps. You used this term as well, Jordan, "production excellence." And when we talk about who needs observability, I was thinking a bit about that while you were talking. And for me, production excellence, or in Apptio we call it production readiness, operational readiness and that sort of stuff is like we want to deploy something to production like what sort of best practices do we want to have in place before we do that? And I think observability is a real great idea, because it's helping you in the future. You don't know what problems you're going to have down the line, but you're equipping your teams to be able to respond to those problems easily. Whereas, we've all probably been there, we've deployed code of production and we have no observability, we have a huge outage. What went wrong? Well, no one knows, but we know this is the fix, and it's hard to learn from that, or you have to learn from that I guess, and protect the user against future stuff, yeah.

Jess Belliveau:

When I think easy wins for observability, the first thing that really comes to mind is this whole idea of structured logging, which is really this idea that your application is you're logging, first of all. Quite important as a baseline starting point, but then you have a structured log format which lets you programmatically pass the logs as well. If you go back in time, maybe logging just looked like plain text with a line, with a timestamp, an error message. Whatever the developer decided to write to the standard out, or to the error file or something like that. Now I think there's a general move to having JSON, an actual formatted blob with that known structure so you can look into it. Tracing's probably not an easy win. That's a little bit harder. You can implement it with open telemetry and libraries and stuff. Requires a bit more understanding of your code base, I guess, and where you want tracing to fire, and that sort of stuff, parsing context through, things like that.

Jordan Simonovski:

I think Atlassian, when you probably just want to know that everything is okay. At a fairly superficial level. Maybe you just want to do some kind of up time on a trend. And then as, I guess, your code might get more complex or your product gets a bit more complex, you can start adding things in there. But I think actually knowing or surfacing the things you know might break. Those would probably be your quickest wins.

Jess Belliveau:

Well, let's mention some things for further reading. If you want to go get the whole picture of the whole, real observability started to get a lot of movement out of the Google SRE book from a few years ago. The Google SRE stuff covers the whole gamut of their soak reliability engineering practice, and observability is a portion of that, there's some great chapters on that. O'Reilly has an observability book, I think, just dedicated to observability now.

Jordan Simonovski:

I think that's still in early release, if people want to google chapters.

Jess Belliveau:

The open telemetry stuff, we'll drop a link to that I think that's really handy to know.

Angad Sethi:

From [inaudible 00:26:12], which is my perspective, as a developer, say I wanted to introduce cornflake use Datadog at Easy Agile. Not very familiar, I'm not very comfortable with it. I know how to navigate, but what's a quick way for me to get started on introducing observability? Sorry to lock my direct job or at my workplace.

Jordan Simonovski:

I would lean, I could be biased here. Jess correct me or give your opinion on this, I would lean heavily towards SLO's for this. And you can have a quick read in the SRE-

Jess Belliveau:

What does SLO stand for, Jordan?

Jordan Simonovski:

Okay, sorry. Buzz words! SLO is a service level objective, not to be confused with service level agreement. An agreement itself is contractual and you can pay people money if you do breach those. An SLO is something you set in your team and you have a target of reliability, because we are getting to the point where we understand that all systems at any point in time are in some kind of degraded state. And yeah, reliability isn't necessarily binary, it's not unreliable or reliable. Most of the time, it's mostly reliable and this gives us a better shared language, I guess. And you can have a read in the SRE handbook by Google, which is free online, which gives you a pretty good understanding of Datadog.

Jordan Simonovski:

I think the last time I used it had a SLO offering. But I think like I was mentioning earlier, you set an SLO on particular functionalities or features of your application. You're saying, "My user can do this 99% of the time," or whatever other reliability target you might want to set. I wouldn't recommend five nines of reliability. You'll probably burn yourself out trying to get there. And you have this target set for yourself. And you know exactly what you're measuring, you're measuring particular types of functionality. And you know when you do breach these, users are being affected. And that's where you can actually start thinking about observability. You can think about, "What other features are we implementing that we can start to measure?" Or, "What user facing things are we implementing that we can start to measure?"

Jordan Simonovski:

Other things you could probably look at are, I think they're all covered in the book anyway, data freshness in a way. You want to make sure the data users are being displayed is relatively fresh. You don't want them looking at stale data, so you can look at measuring things like that as well. But you can pretty much break it down into most functionalities of a website. It's no longer like a ping check, that you're just saying, "Yes, HTTP, okay. My application is fine." You're saying, "My users are actually being affected by things not working." And you can start measuring things from there. And that should give you a better understanding, or a better idea, at least, of where to start with what you want to measure and ow you want to measure it. That would be my opinion on where to get started with this if you do want to introduce it.

Jared Kells:

We're going to talk a little bit about state and how with some of these, like our very front end heavy applications that we're building, so the applications we build just basically run inside the browser and the traditional state as you would think about it, is just pulling a very simple API that writes some things into the database with some authentication, and that sort of stuff. So in terms of reliability of the services, it's really reliable. Those tiny API's just never have problems, because it's just so simple. And well, they've got plenty of monitoring around it. But all our state is actually, when you say, "Observe the state of the system," for the most part, that's state in a browser. And how do we get observability into that?

Jess Belliveau:

A big thing is really, there's not one thing fits all as well. When we talk about the SLO stuff as well, it's understanding what is important to not so much maybe your company but your team as well. If you're delivering this product, what's important to you specifically? So one SLO that might work for me at Apptio probably isn't going to work for Easy Agile. This is really pushing my knowledge, as well, of front end stuff, but when we say we want to observe the state as well, we don't necessarily mean specifically just the state. You could want to understand with each one of those API's when it's firing, what the request response time is for that API firing. So that might be an important metric. So you can start to see if one of those APIs is introducing latency, and so your user experience is degraded. Like, "Hey when we were on release three, when users were interacting with our service here, it would respond in this percentile latency. We've done a release and since then, now we're seeing it's now in this percentile. Have we degraded performance performance?" Users might not be complaining, but that could be something that the team then can look into, add to a sprint. Hey, I'm using Agile terms now. Watch out!

Jared Kells:

That's a really good example, Jess. Performance issues for us are typically not an API that's performing poorly. It's something in this very complicated front end application is not running in the same order as it used to, or there's some complex interaction we didn't think of, so it's requesting more data than expected. The APIs are returning. They're never slow, for the most part, but we have performance regressions that we may not know about without seeing them or investigating them. The observability is really at the individual user's browser level. That makes sense? I want to know how long did it take for this particular interaction to happen.

Jess Belliveau:

Yeah. I've never done that sort of side of things. As well, the other thing I guess, you could potentially be impacted in as well as then, you're dealing with end user manifestations as well. You could perceive-

Jared Kells:

Yeah sure.

Jess Belliveau:

... Greater performance on their laptop or something, or their ISP or that sort of stuff. It'd be really hard to make sure you're not getting noise from that sort of thing as well.

Jordan Simonovski:

Yeah. There are tools like Sentry, I guess, which do exist to give you a bit more of an understanding what's happening on your front end. The way Sentry tends to work with JavaScript, is you'll upload a minified map of your JS to Sentry, deploy your code and then if something does break or work in a fairly unexpected way, that tends to get surfaced with Sentry will tell you exactly which line this kind of stuff is happening on, and it's a really cool tool for that company stuff. I don't know if it'd give you the right type of insights, I think, in terms of performance or-

Jared Kells:

Yeah, we use a similar tool and it does work for crashes and that sort of thing. And on the observability front, we log actions like state mutations in side the front end, not the actual state change, but just labels that represent that you updated an issue summary or you clicked this button, that sort of thing, and we send those with our crash reports. And it's super helpful having that sort of observability. So I think I know what you guys are talking about. But I'm just [crosstalk 00:35:25], yeah.

Jess Belliveau:

Yeah, that's almost like, I guess, a form of tracing. For me and Jordan, when we talk about tracing, we might be thinking about 12 different microservices sitting in AWS that are all interacting, whereas you're more shifting that. That's sort of all stuff in the browser interacting and just having that history of this is what the user did and how they've ended up-

Jared Kells:

In that state.

Jess Belliveau:

In that state, yeah.

Jordan Simonovski:

I guess even if you don't have a lot of microservices, if you're talking about particular, like you're saying for the most part your API requests are fine but sometimes you have particularly large payloads-

Jared Kells:

We actually have to monitor, I don't know, maybe you can help with this, we actually should be monitoring maybe who we're integrating with. It's actually much more likely that we'll have a performance issue on a Xero API rather than... We don't see it, the browser sees it as well, which is-

Jordan Simonovski:

Yeah, and tracing does solve all of those regressions for you. Most tracing libraries, like if you're running Node apps or whatever on your backend. I can just tell you about Node, because I probably have the most experience writing Node stuff. You pretty much just drop in Didi trace, which is a Datadog library for tracing into your backend and your hook itself into all of, I think, the common libraries that you'll tend to work with, I think. Like if you're working for express or for a lot of just HADP libraries, as well as a few AWS services, it will kind of hook itself into that. And you can actually pinpoint. It will kind of show you on this pretty cool service map exactly which services you're interacting with and where you might be experiencing a regression. And I think traces do serve to surface that information, which is cool. So that could be something worth investigating.

Jess Belliveau:

It's funny. This is a little bit unrelated to observability, but you've just made me think a bit more about how you're saying you're reliant on third party providers as well. And something I think that's really important that sometimes gets missed is so many of us today are relying on third party providers, like AWS is a huge thing. A lot of people writing apps that require AWS services. And I think a lot of the time, people just assume AWS or Jira or whatever, is 100% up time, always available. And they don't write their code in such a way that deals with failures. And I think it's super important. So many times now I've seen people using the AWS API and they don't implement exponential back off. And so they're basically trying to hit the AWS API, it fails or they might get throttled, for example, and then they just go into a fail state and throw an error to the user. But you could potentially improve that user experience, have a retry mechanism automatically built in and that sort of stuff. It doesn't really tie into the observability thing, but it's something.

Jared Kells:

And the users don't care, right? No one cares if it's an AWS problem. It's your problem, right, your app is too slow.

Jess Belliveau:

Well, they're using your app. Exactly right. It reflects on you sort of thing, so it's in your interest to guard against an upstream failure, or at least inform the user when it's that case. Yeah.

Jared Kells:

Well, I think we're going to have to call it, this podcast, because it was an hour ago. We had instructed max 45 minutes.

Jess Belliveau:

We could just keep going. We might need a part two! Maybe we can request [cross talk 00:39:21].

Jared Kells:

Maybe! Yeah.

Jess Belliveau:

Or we'll just start our own podcast! Yeah.

Angad Sethi:

So what were your biggest learnings today, given it's been Angad and I are just learning about observability, Angad what was your biggest learning today about observability? My biggest learning was that observability does not equal Datadog. No, sorry! It was just very fascinating to learn about quantifying the known unknowns. I don't know if that's a good takeaway, but...

Jess Belliveau:

Any takeaway is a good takeaway! What about you, Jared?

Jared Kells:

I think, because I we were going to talk about state management, and part of it was how we have this ability, at the moment to, the way our front ends are architected, we can capture the state of the app and get a customer to send us their state, basically. And we can load it into our app and just see exactly how it was, just the way our state's designed. But what might be even cooler is to build maybe some observability into that front end for support. I'm thinking instead of just having, we have this button to send us out your support information that sends us a bunch of the state, but instead of console logging to the browser log, we could be console logging, logging in our front end somewhere that when they click, "send support information," our customers should be sending us the actions that they performed.

Jared Kells:

Like, "Hey there's a bug, send us your support information." It doesn't have to be a third party service collecting this observability stuff. We could just build into our... So that's what I'm thinking about.

Jess Belliveau:

Yeah, for sure. It'll probably be a lot less intrusive, as well, as some of the third party stuff that I've seen around.

Jared Kells:

Yeah. It's pretty hard with some of these integrations, especially if you're developing apps that get run behind a firewall.

Jess Belliveau:

Yeah

Jared Kells:

You can't just talk to some of these third parties. So yeah, it's cool though. It's really interesting.

Jess Belliveau:

Well, I hope someone out there listening has learned something, and Jordan and I will send some links through, and we can add them, hopefully, to the show notes or something so people can do some more reading and...

Jared Kells:

All thanks!

Jess Belliveau:

Thanks for having us, yeah.

Jared Kells:

Thanks all for your time, and thanks everybody for listening.

Jordan Simonovski:

Thanks everyone.

Angad Sethi:

That was [inaudible 00:41:55].
