Transcript context
…Along those lines, where do you find people are leveraging AI most in helping them through these sprints, through either the foundation sprint or the design sprint? Is it mostly just vibe coding prototypes? That's definitely the first and biggest use of AI in sprints so far is in making prototypes that look more realistic faster. It's kind of like having an entire prototyping team on standby so that you don't have to just make it yourself and sort of piece things together, but you can have a ton of people ready to jump in, make something look really realistic. It's also really critical we found that while you're outsourcing that prototyping work, you don't outsource the thinking. You don't kind of skip over the part where you think about, "Well, what is the actual copy on the website? How do I actually describe what the product is, how it's differentiated?" It's one of the reasons why doing the foundation sprint first and then doing a design sprint can really help you, because it allows you to spend time working on that harder part of what it means to design and build a product. Then, once you have a clear view of that, then you can use AI tools to go really fast. In this example that Jake is showing of Axion Orbital, people get really clever about which parts of this need to be real, which parts of this can be vibe coded, which parts of this can just be a static Figma mockup. It's all about kind of creating a simulation, something that looks realistic, that you can put in front of real customers to help you answer the key questions. That's a really good point that you're making. Again, it's just a reminder, you'll move faster if you slow down a little bit at the beginning, that because prototyping is so easy now and just things that look ... It's so easy to make something that looks really nice and kind of it's doing what you want, but spending a little time making sure you understand what you're testing and what you want becomes more important.…
