Sort of related, but this is one reason I moved into “Frontend“ about 10 years ago. I started seeing over and over that when our (SaaS) projects didn’t start from what the customer sees, teams usually got distracted with imaginary or hypothetical design issues. It was a lot more effective to iterate from the visible features, and then let that drive much of the backend design, APIs, development timeline, etc.

This meant I needed to deal with more JavaScript than I originally intended with my career, and eyerolls from backend architect types, but projects go much smoother than in my past, that's for sure.
