Defining an ambiguous term

[00:00:00] Host: New frameworks are super exciting, but depending on the needs of your org it may vary. We have a wonderful panel of Amanda, Alex, Teresa and Ryan coming on stage. I think we're ready, so I'll go ahead and welcome them. Give them a round of applause.

[00:00:25] Amanda: Hi everyone, good afternoon. Frameworks: kind of a ubiquitous word. Raise your hand if you've heard someone mention a framework today, or yesterday. Yeah, most of you. I'm a researcher, so I've noticed patterns and behaviors and those kinds of things, and I noticed that at least 50 percent of presentations mention the word framework, and they were all used very differently. By way of introduction, let's put some specificity around this ambiguous term. How are we defining frameworks? How are you thinking about them? Teresa, we'll start with you.

[00:00:59] Teresa: Sure, I'll kick things off. How I really look at defining a framework is putting a process together that can really bring a team together and really create that synergy to be able to implement any concept or any style that you're looking to adapt at your organization.

[00:01:17] Amanda: Yeah. Ryan?

[00:01:20] Ryan: I see a framework as really just a set of guidelines, something that you can use to help organize, prioritize, figure out what you need to get done, but also understand that a framework needs to be very flexible and just easily adaptable to change.

[00:01:37] Alex: I agree with these two, but I'm also coming from the tech lens. I think of frameworks in a number of different ways. Of course, if you're in tech right now you might think of a framework as a JavaScript framework, so there's that approach, but then there's also the framework that I think we'll be focusing on today, which is more around the processes, and making sure that we have things in place to spark innovation, make sure that we have the creativity that we need to build and design the things that we need to for our users.

What each team actually uses

[00:02:09] Amanda: Frameworks. Alex, what are you thinking about at T. Rowe?

[00:02:13] Alex: Well, for tech we use agile on the product development life cycle to build on that, and we also use agile on our design side. We use Double Diamond for design, to kind of have that divergent thinking. But that's the main set that we use.

[00:02:32] Amanda: Yeah. Ryan, how about over at Priceline?

[00:02:35] Ryan: Yeah, I'm probably a little bit unique here in that I don't actually have a favorite framework. I think you need to understand what works best for your team, for your brand and for your project, and that becomes your framework. We are very agile. We're also lean. I could also argue at times maybe there's a little bit of waterfall, depending on — every now and again there's a project with a longer runway, and then maybe we become a little bit more hybrid where we're incorporating different frameworks. But that's how we work. Again, to me it's finding the right thing for the situation that you're in.

[00:03:11] Amanda: And Teresa, you just wrote a whole book about this.

[00:03:12] Teresa: I did.

[00:03:13] Amanda: So talk to us a little bit about how you're thinking about this.

[00:03:16] Teresa: Yeah, the two-hour experience, absolutely. The book is called Solving Problems in Two Hours, and at TreviPay we actually have around 20 engineering teams that we have supporting product, UX and design managers, really supporting those roles. Obviously this is a really big framework we use. The framework is really a two-hour design sprint, so it takes the best of both worlds from design thinking and design sprint methods, and allows your team to really come together with the solution in those two hours. I know a few of you are going to be joining the workshop on that tomorrow, so I'm excited to see you in that. Ultimately, with this process we complete anywhere from 20 to 40 two-hour design sprints a year, and we have been for the last three years. It's a really great framework that we use and I look forward to chatting more about that.

Organizing people around a framework

[00:04:02] Amanda: Yeah. Ryan, Teresa, you also have organizations and teams under you. I'm curious how you organize people around frameworks.

[00:04:12] Teresa: Yeah, let me kick that off. Sure, all right. Ultimately, I talked a bit about having 20 engineering teams at TreviPay, and I'm really happy to be over product, UX and design, so that makes it a little easier in terms of bringing the teams together and working with the tech folks like Alex and his teams. Different companies, but the same engineering types. What I love about frameworks in general is bringing stakeholders together across all those different orgs to create that unity and create the stakeholder buy-in. Ultimately, for me, why we implement frameworks at TreviPay — and while it's easier to do that from the product, UX and design side — ultimately by leading those efforts you're bringing together engineering orgs, account management, sales, really bringing together the entire organization and your CEO, with selling what you're trying to solve as an organization to get more customers, or become more rapid at prototyping or releasing features, whatever your goal is as an org.

[00:05:16] Ryan: Yeah, I guess I think of it more in terms of my team. I really want my team to have the autonomy to be the subject matter experts for the projects that they're working on, and how they work within their teams, because it works best for that team. But I try to put a framework in place for my team that allows collaboration, that allows a good process for reviewing work both synchronously and asynchronously, and then also knowing that they have other teammates that are there to help and support them when it comes to brainstorming and coming together for quick reviews. For me, when I'm thinking about a framework, it's more about bringing a team together to help make sure people are in the right place to do the work that is needed.

[00:06:04] Alex: Yeah, I come from a similar approach, in that we just want to make sure that we have enough processes to get the work done. We want to make sure that we're getting the work done in the right way, but also quickly. Using agile, and having the different roles on that team, making sure that we're getting the work done on time, that's really key to us. But then also, we have a lot of different people that we work with. Our designers for our design system, which is my main focus, are in London, and we've got our developers in the US, so making sure that there's good process around how we all work together and make sure that we're constantly feeding into each other's workflow is really important. So that's how we tackle that.

When is it time to bring in something new

[00:06:50] Amanda: Our panel's on when to adopt a new framework. I'd be remiss in not asking the question: when? What is the time in which you were thinking about introducing something new? Teresa, we'll start with you.

[00:07:01] Teresa: Yeah, I really think anytime is a great time, but especially now. We work in the fintech space at TreviPay. We're global fintech, we process six billion in transactions a year, and when I started at this org five years ago we had five key competitors in the space. In the last three years we have over 45. So that's the time to implement a new framework. How can you really use a new framework to be more competitive, to get more features out ahead of your competitors, or gain user adoption? By using the two-hour design sprint method that I talked about earlier from the book, we are able to implement features a lot faster, and with that we've actually increased our user adoption over 300 percent throughout the entire COVID pandemic, as well as increased our revenue 30 percent. So those are ways that we use a new framework to try and get ahead of the competition, build user adoption and really gain that traction to get ahead of our competitors in the fintech space.

[00:08:00] Amanda: And digging in a little deeper there, what is specifically the framework or frameworks that you're bringing to the forefront as you're thinking about that competitive space?

[00:08:09] Teresa: Yes, we really implement the two-hour design sprint method from the book Solving Problems in Two Hours, so that really is the core method. However, we are an agile shop. We run lean, we run kanban, and really we implement a lot of really great collaborative tools. I'm a huge fan of Figma and FigJam, and that cross-collaboration allows us to not just work in our US office — we have teams in Australia, the Netherlands, the US, Dubai, all over. Ultimately, by implementing that new framework, when you do that you need to make sure that you are able to meet all of your stakeholders all over the country, as well as your customer. A big part of the framework, for those that haven't participated in a design sprint, is you are validating what you are putting together as a solution as a team, with your customers, before you implement it. And then you're able to bring it right into the agile cycle of your next agile sprint, or kanban, or however you're pulling work down as a team.

[00:09:12] Amanda: Alex, when?

[00:09:14] Alex: Well, I think when the current solution isn't working well is probably when, but identifying that is key. What we do, especially on the tech side, is we'll have our retrospectives and we'll talk amongst the team and figure out what's going well, what's not going well, and if something's not, then we try to put in place some new process, some new framework that makes sense for our team. Of course, that may not make sense to another team that's adjacent in their work, but it would work best for us. Then we do the same thing with design. As a part of the design system we have our technical retrospectives, but we also, on a lesser cadence — not as often — we meet with design as well and try to make sure that we have a retrospective there, so that way our global process, we know works as it should.

[00:09:58] Amanda: And take us behind the scenes a little bit. What does that look like when something's not working? You don't need to share anything confidential, but give us a little bit more about how that all plays out.

[00:10:07] Alex: Sure thing. One thing that we know, just as an example, is that we were lacking in our ability to innovate and having time to do that. While it wasn't a named framework, we realized that we had a need to consistently make sure that we had time for that on the dev side. What we've incorporated is a new process, so that way a single dev will have a full eight-hour day every sprint to work on something that will improve the design system. Once they're done with that, then they present it to the group, and then we either work on that thing or recognize it as something that we tried but maybe didn't work, or maybe it was just research that would help us grow as a design system. That's just an example of when we implemented a new process that worked best for us. Hope that answers it.

[00:10:59] Amanda: Yeah, thanks.

[00:11:01] Ryan: Yeah, I agree. I think if something's not working and you're completely stuck, then maybe you have to rethink what you're doing and how you're doing it. But I also think that with any framework, any process, it's just really important that you constantly take a look at that framework or process and think about what's working really well, what can we be doing better, and what do we need to change. Because again, they're flexible, and I think there's always an opportunity to revisit how you're working and think of ways that it might work better in the next sprint or in the next quarter, and just keep on reevaluating.

[00:11:37] Alex: I think, though — and I agree with what you're saying — it's important to have success criteria for your current process, because if you don't know what success looks like, how do you know when to switch? I would suggest work with your teams to best understand what that looks like, just kind of like you would do with a definition of done. Make sure that you have that set, so that way if you're deviating from that and you're no longer aligned with what your success criteria is, then you know you need to adopt something new.

[00:12:06] Teresa: I think, just to add to that as well, I know that we all hop on LinkedIn every day and we see the number of layoffs that are happening, so there's a lot of shifting in teams going on. Really defining that success criteria, knowing that that criteria can change over time too, especially if you are having to reduce your teams or shift who's working on different projects — that's also a great time to bring in a framework, when you are going through something like that as an org, and bringing that type of framework in.

The rise and fall of frameworks, and personas

[00:12:36] Amanda: Yeah. Let's get a little spicy for a minute. We've been around for a while. Some frameworks rise to fame, some frameworks sometimes get pushed down. I'm thinking particularly of user personas. In the past few years there's really been a lot of push against that, and that, when I was starting out, was the gold standard of a particular framework that you would use for research. Whereas jobs to be done — we heard a talk about it yesterday — has also kind of risen to its glory. I'm kind of curious what you attribute to these trends in the rise and fall of particular frameworks, and then also what your take is on personas.

[00:13:10] Teresa: Well, I'll start that off, because I know I'll have some fun debate on it. I love personas. I actually have a few UX team members here from TreviPay, so I'm always going to talk positive about that because they're here. No, I'm kidding. User personas: really big fan. We actually integrate user personas at the core of our framework at TreviPay. We have a really talented UX team — I'm not just saying that because they're out there — and 20 to 30 user personas is what we have across all of our products, and we update those every six months. By doing that, we are interviewing customers constantly to keep these personas up to date and make sure they are non-biased, that there are no — those of you who joined the accessibility session earlier — making sure that we're really thinking about who our customers are, not just from what we know of them one time and meeting them, but really continuing to measure over time. We do a lot of on-sites to do this. GM is a really big client of mine, so we actually just sent a couple of team members out on site and we were able to see what each persona was dealing with in their day-to-day. With that, we take those personas, and every single user story we write — we're agile, so we try to include personas in everything that we're doing, in every decision that we make, with those personas.

[00:14:30] Amanda: All right, Ryan, go at it.

[00:14:33] Ryan: Yeah, I do like personas. I can't say I don't like personas. What I would say is, historically, in the span of 20-some years I've seen a lot of personas created. I've been involved, even working on the agency side where brands come to you and actually pay a lot of money to have you talk to customers, look at data and create personas, and you make them and they look all pretty, and then they just go on a shelf somewhere, or they go in a drawer. It's kind of like you check the box: you created a persona, but the persona wasn't necessarily used. So I think personas are a great tool when they're actually used properly, and it's not a one-and-done thing. It's not going out and saying we did personas, and they're — this is Alex, or whatever — and then it just sits there. You don't use it. You have to continuously look at those personas and figure out how they adapt and change, just like anyone's users do and your customers do, because I guarantee you that they change what they need, change when they need it, and that kind of needs to live in the persona. So my issue isn't — it's not, I don't have an issue. Wrong choice of words.

[00:15:36] Amanda: You can have an issue.

[00:15:41] Ryan: But I just feel like I've seen them used improperly more so than used properly, and I think when they're done right and brands really buy into it — and that's the other piece of it, I think there's a cultural thing.

ChatGPT, validation and what personas are worth

[00:15:53] Teresa: Yeah, that's funny. Just to add to that before we get to Alex, who might be adding more to what you're saying: with personas, one of the questions I got asked just a couple of weeks ago was, hey Teresa, can you use ChatGPT to write user personas for you and replace UX research altogether? I got asked that question on a live podcast last week and I was like, oh, that's fun, okay, yeah, let's do this. I happen to have a background in AI, in natural language processing — I built a number of text analytics engines in my lifetime — so I've got a particular opinion on that. I said, that's a really great question, and here's how I look at ChatGPT. I like ChatGPT as an additional resource to go build your user personas. You could use it to go validate. And right on that podcast I was like, well, let's find out. I pulled up ChatGPT right there on the podcast and I did a search and I was like, ChatGPT, tell me what the user persona would be for a buyer that's looking to get credit for their business, which is what we do at TreviPay. I just threw that in there, and sure enough, ChatGPT says, here's your persona, and it got about 700 words and bullet points on what that persona would be. But what was missing was — again, this goes back to validation for user personas. If you just put them on a shelf and you're not validating them, there's no value in it. The same with ChatGPT: if you're not going and then taking that and validating it and meeting with customers, you're probably not going to get a lot of value out of it. So I think yes, ChatGPT can be used as an additional research tool, and yes, if you're just putting them on a shelf then you might as well not do them, because you're not getting value out of them.

[00:17:30] Ryan: Yeah, to the point of ChatGPT, I think it also becomes something that is going to become a skill that I think most people are going to need to learn how to work with, because ChatGPT is only as good as the prompts that you're asking it. And I do think that there's an art to asking the right prompts and then getting those inputs and turning them into something meaningful. ChatGPT is not a human. We don't know. Well, that's the one answering quickly every time. Good point. As far as I know, at this moment, it is not a human. We might learn something different next week. But I think having a human being look at what ChatGPT is telling you and figuring out how to humanize what's coming out of it, I think that's where it becomes really powerful, and it can certainly help with persona work.

[00:18:21] Alex: Yeah, if you want to go on that thread for just a moment: I think ChatGPT is really an interesting product and has a lot of great use cases, but I heard it said once, and I love this phrase, that it's 100 percent confidence but not 100 percent accuracy. So everything that we do and we put into it, we also have to take a look at and make sure that we're reviewing it, at least at this stage. Going into user personas though, I have a different perspective coming from the tech side, but I'm also really focused on design systems, and of course we have that kind of thing especially on the design side, when we're making sure that we're making the right calls for the designs that we're creating. But we can also take the same approach on the tech side, and we actually do that. It's a little bit less rigid in the way that we go about it, but we have our own users. We have to make sure that our developers are being taken care of, that our authors are able to actively make sure that it's a very strong experience for them when they're authoring the content on the site, because we actually create those experiences for them. I hammer home with the folks on our development team just how important that is. Making sure that we're constantly thinking about the user and making sure that we have the right idea of what they want is just really important to the way that we build our design system. Going beyond that, we also do research with our developers internally. We recently did some research asking them what they liked about the design system, what they didn't like about the design system, how we could improve, and then that helps feed back into our informal, if you will, user personas that we use when we think about how we cater to each of these different users.

When a framework belly-flopped

[00:20:07] Amanda: So tell us about a time when a framework didn't work. What is something that one of you tried — perhaps you had a great idea, you were trying to introduce some new framework to a team, and it just belly-flopped?

[00:20:22] Ryan: Yeah, I can start on this one. Years ago I worked at a company and they trained everyone to work — I think it's called EOS, I think it's Enterprise Operational System, something. We'll just say that that's what it is for the point of this. They trained everyone how to work within that methodology, and it was a way of tracking issues, looking at data, understanding what people were doing, understanding where their problems are, and then every week you have something they call a level 10 meeting. So you have a level 10 meeting with your team, and it worked great there. But it was also part of the culture. We were all trained to use it, but for me it just became what I was used to. I left that job and I went somewhere else and I was like, well, obviously this is how this team is going to work. We're going to implement EOS and we're going to start having these level 10 meetings. I got there, and probably for about two months I was trying to do this, and no one was taking part, because this really only works when it's collaborative and everyone's giving inputs and part of the actual process. Nobody was doing it, and what I realized is, this makes absolutely no sense here. There's probably much better ways to think about process and a framework for how we all work. Kind of like Mario talked about yesterday in terms of reading the room: I didn't do a good job reading the room. I should have realized pretty quickly that that was the wrong framework or the wrong approach to bring at the time. It's really: where are you, who are you working with, talk to the people you're working with and figure out the best way to work within that group.

[00:22:00] Alex: Yeah. Within the design system, we used to follow a different approach where there was a bit of waterfall effort going on on the design side, and then eventually that fed into dev. But the designers who were focusing on building the design system were at the experience level, based on the experience needs, and we found that that really didn't work well for us, because we didn't get the holistic view of how an individual component should work across all of these different experiences. So we ended up having to change the way that we worked, and we're now moving much faster and we have a much better and more thorough set of components, just the way that they — the behavior behind each one of them, and making sure that they have all the features. It's much clearer for us to understand.

[00:22:43] Amanda: I'm glad you talked about that.

[00:22:47] Teresa: It's not going to shock you to hear me talk about the process. We moved to two-hour design sprints, but for those that don't have the history of design thinking, or have ever been in that, it's very similar to a waterfall approach. I know there's someone from Stanford here, who I was talking to earlier about how much I love the Stanford design thinking process. The Stanford and IDEO design thinking processes really took months to years, like waterfall, to really come up with a solution and then implement that with your release. Then comes 2016, Jake Knapp, the team at Google Ventures, and they created the five-day design sprint. How the two-hour design sprint method even ended up coming about — besides the COVID-19 pandemic really giving a lift there with everyone going remote — was really being able to move quicker.

[00:23:33] Teresa: We had a really big five-day design sprint failure. The concept was on creating a new — I talked about ChatGPT — for the most part it was a dashboard that would automatically provide action for users that went to it and told them what to do, like ChatGPT would do. I wish that would have been around, that would have been maybe my solution. I'm kidding. With that dashboard concept we ran a five-day design sprint, we put the prototype in front of users on day five, and they're like, this is horrible, I'm not going to use this. We ran two more design sprints, spent over a hundred and fifty thousand dollars bringing in a third party using this five-day model. Ultimately that failure allowed for innovation and creativity to find better methods, and the two-hour design method didn't come for a little bit further. But from there we reduced down to four days, three days, two days, one day. No matter what you take out of that: if you're running design sprints at your org, you don't need a full five days to figure out whether the solution is going to work for your users, and if you could find that time sooner, whether it's two hours or one day, you'd be able to understand whether you have the right solution to move forward. That's what you should take away from those failures. Failures really help innovation, in my opinion.

One piece of advice

[00:24:50] Amanda: Absolutely. Okay, final question for me, and then we're going to open it up to the audience for a few questions, so start thinking. What is one top piece of advice you would give all of us that are starting to think about adopting a new framework? One succinct thing that we should keep in mind.

[00:25:07] Teresa: I think my advice would be go for it. You have nothing to lose. I think that sometimes we go into new frameworks more risk-averse, and if you're not taking those risks you're not going to be able to accelerate above your competitors. It is such a saturated market right now, there's layoffs going on, now is the time to take risks and be able to create that innovation and facilitate that creativity with your team. So my advice is just go for it, try all the frameworks, and do what works best for your org, and you'll be surprised by that. And also, try the two-hour design sprint method. No, I'm kidding.

[00:25:43] Ryan: Good, right? Yeah, I think something similar. Don't be afraid to break the rules. There's no rules when it comes to frameworks, and don't be afraid to try new things. Failing is okay. But the important thing is thinking about what you need to get done and figuring out the best way to do it, despite what any particular framework or process or methodology might tell you is the right thing.

[00:26:08] Alex: Yeah, I think it's good to do your research, take a look at what industry trends are out there, but even if it works for one company it may not work for your company, or even your team within a company. So just take a look at what your own requirements are and what problems you're trying to solve. There may not even be an existing framework that fits the need that you have, and so you might have to come up with something on your own. You could promote it in a talk if you want to. But yeah, that's what I would suggest.

Q&A

[00:26:39] Amanda: Wonderful. A few minutes left for any questions from any of you. I see some good hands. Can we get the mic, that thing? I think it's dangerous. All right, there's a question here, I think. Yeah, okay. Ready, here we go. Oh, so close.

[00:27:05] Audience: Football, whatever. Thank you, that was amazing, the throw, also the panel. Oh my God, I had my question somewhere, now where are they? Sorry, here they are. Okay, I had two questions, thank you very much. I had two questions. First of all, we're throwing some buzzwords here: can you break down, high level, the two-hour design sprint, because I heard it many times and I don't know what that means? So that's one thing, and then I have a question for you as well.

[00:27:33] Teresa: Okay. Yeah, with the two-hour design sprint process: most of you, I assume, maybe have been exposed to a five-day model where you're breaking down five stages. The two-hour design sprint model focuses on understanding our users and problem, and then really going through there and being able to ideate a solution. So it breaks it down into a three-stage model. And since you asked a question, if you come find me I can send you an ebook, or a book, because I love that you asked a question about it. But ultimately what you're doing is you're facilitating that process that went from five stages down to three, and you're coming up and you are even sketching at the end of this two hours and ideating as a group on what you could solution. For those that are participating in the workshop tomorrow, we are going to be doing this exact exercise. You'll be participating in a two-hour design sprint so you can see it firsthand. But yeah, if anyone wants to find me, I'm happy to pass that along.

[00:28:30] Audience: Another question for Ryan. We talked about breaking it — but I'm trying, maybe this is working better. Really quickly: adopting a new framework requires governance and requires process on morning[?]. I wanted to ask you about a case-by-case basis, and who you should partner with when you try to copy this new framework without burning too much time or effort on the governance side. Who would you recommend to partner with?

[00:28:49] Ryan: Yeah, so from the user, designers, 100 percent, developers, and product management. Find a PM, find a developer, and I think that that's the right starting point. To scale, though — but I'll come up with that later. All right.

[00:29:18] Audience: Thank you so much. Hi, so I'm Lindsay from Priceline. Great talk, everyone. The question that I think was occurring to me, and it sort of echoes, Amanda, what you were talking about with personas and when they sit on a shelf and they're not used, what do we do — I'm just sort of curious. Many of you echoed the importance of that cultural buy-in for new frameworks. We have a lot of different types of roles sitting in this room and online, and what I'm really curious about is what tips or advice you would give to the sort of larger group. Let's say they have identified the problem, they think there might be a framework that they can either use as is or adapt: how would you guide folks into thinking about how to position that within the larger organization and really leading that charge?

[00:30:07] Ryan: I didn't know if that was a plug question. Should I let you go? I think she —

[00:30:10] Teresa: Okay, I'll take it, I'll take it. Priceline, you know. She knows where to find me. Okay, no, that's a really, really great question. Ultimately, in facilitating that stakeholder buy-in, that's really number one. That's really where that model, whether you're running a two-hour design sprint, a five-day, or a workshop — anytime you're able to bring together a group of stakeholders across departments to collaborate together, that's how you build the buy-in. That's why, when I mentioned we use about 20 to 40 of these a year at TreviPay, we're not just doing that for fun and to get things out the door. We're also doing that to get that buy-in. This is especially important if you are in a large organization — we have around a thousand employees — or a startup that's just got a handful, because they each have their different challenges. In a large organization you have a lot of different stakeholder groups, varying opinions and interactions with customers, and so if you can use a method like a two-hour or five-day design sprint or a workshop, you can use that opportunity to understand where each department is coming from and bring everyone together as the moderator in that solution. Then when you get ready to have the solution, you now have all these cheerleaders behind you that are ready to go and excited about that solution. So that's what I love about that.

[00:31:27] Amanda: One question I would ask real quick, and I know we're out of time: did TreviPay always have that culture of collaboration?

[00:31:32] Teresa: No, we did not. We did not always have it. It's been a challenge, but this method, and really just that nature of the diverse collaboration that we have with Figma, FigJam and all the in-person hybrid events, has allowed us to build that up. So I really do think that UX, and a culture of design thinking and design sprints, has allowed us to build that culture that I really think is a thriving culture, and why we're here today. We're excited to talk about it.

[00:32:03] Amanda: That's great. Yeah. Alrighty, we're at time. Let's give our panel a round of applause. Thank you so much.
