Fast Delivery Isn't Enough. You Need Fast Feedback.

It's demo day. Claude Code knocked out the data layer migration in two days. So the team pulled in more backend work—cleaner API contracts, better abstractions. Might as well use the time. The product manager asks: "So what can users do now that they couldn't do before?" Silence. "Nothing yet. But the next feature will be way faster to build." She nods. You can tell she's already thinking about how to explain this to stakeholders. A full sprint of AI-accelerated work. Users have seen nothing. Feedback: zero. And you're moving faster than ever—on top of assumptions you've never validated. The Real Constraint Isn't Coding Speed Your developers can now code faster with AI coding assistants. That's incredible. But faster coding doesn't automatically lead to better products. The real waste in software development isn't slow coding—it's building the wrong product or feature. As Marty Cagan from Silicon Valley Product Group puts it: "The biggest waste in software development is building the w
