The more brains working on the hard problems, the better. - Ben Horowitz

Good product managers don’t get all of their time sucked up by the various organizations that must work together to deliver the right product at the right time. They don’t take all the product team minutes; they don’t project manage the various functions; they are not gofers for engineering. They are not part of the product team; they manage the product team. Engineering teams don’t consider good product managers a “marketing resource.” Good product managers are the marketing counterparts to the engineering manager.

When you scale an organization, you will also need to give ground grudgingly. Specialization, organizational structure, and process all complicate things and implementing them will feel like you are moving away from common knowledge and quality communication. It is very much like the offensive lineman taking a step backward. You will lose ground, but you will prevent your company from descending into chaos.

a high quality human resources organization cannot make you a well-managed company with a great culture, but it can tell you when you and your managers are not getting the job done.
