In my experience, but I know I am unconventional, half-organized chaos. You do need motivated, good people for that so. The chaos bit is those people figurong out their stuff themselves, while the organized bit is szrict following up on deliverables, relevant deadlines, flexibility on not-so-relevant ones and, this is crucial, step in in to provide guidance, support decision maling and coordination between peoole and teams. If the latter means setting up a dozen 30 minute meetings between two people, the be it.

Only gets you so far so. And needs everyone being aware of customer needs and requirements.
