We had a very fruitful discussion some months ago, summarized here (in Spanish): https://pinchito.es/2022/quien-lleva-roadmap-producto. In a nutshell: builders must know what they are building, and why. Most product people should be embedded in squads, just like devs, sysadmins or QAs; and they should be under the same management structure as the rest. Having separate structures for technology and product leads to the inevitable divide we often see in product companies. And, at least in technology companies, engineering must set the way forward. Therefore: CTPO.
