All the arguments for where to place control over who decides what gets built IMHO are just political power grabs from one constituency or another. Different companies do it differently, and I'm not sure there is one best way. Any time engineering or product or sales or marketing want more power they come up with some reasons why their function should have more control in every company everywhere.

I don't think arguments that any function should always drive can be true, because who is best qualified to make those decisions is based on things like judgement, experience, domain knowledge, and customer understanding.

Instead of saying a specific function should have control, I think empowering the people who have been best a making decisions about scope should do it is the best approach. That can be engineering but that also can be product etc.
