The roadmap rationed engineering. When a working prototype costs a day, that's no longer the hard part, and Atlassian's October 2026 experience shows what happens when speed arrives without steering: about ten AI-builder projects flew for a few weeks and then stalled, because, in Sherif Mansour's words as Jason Lemkin reported them, everyone was rowing and no one was steering.
So the CPO owns the operating model. The substrate, the listening loop, the eval bar, the org shape, and the margin, each of which gets its own part in the series. Craig Unsworth's warning applies to the ratio debate that usually follows: it's possible to make everybody faster and the company no faster at all. The CPO's question is where decisions get made and how fast the evidence reaches them.
The full argument is Somebody Has to Steer: The CPO Now Owns the Operating Model, part 1 of The CPO Transition. The handbook chapters underneath it are Kill the Roadmap, Engineering Builds the Substrate, Not Features, and Gross Margin Is Your Job Now.
