When AI doubles your development velocity, every bottleneck doubles too.The deferred decision that used to cost you a day now costs a week. Themisaligned requirement that used to create confusion now creates threefeatures built on the wrong assumption before anyone catches it.​

Here's what actually changed when we rebuilt the process:​

We stopped writing "just enough" specs. AI executes too fast for mid-flightclarification. Robust PRDs are in order now.​

And the triad — product, design, engineering — became more important thanever. Not just at kickoff. At every stage.​

Design ahead and present. Engineering building and questioning. Productdeciding in real time, not at the next sprint review.​

The old dual track model: two tracks, coordinated at handoff points.​

The new model: one track, all disciplines in continuous motion together.​
