Slow follow through can sometimes get out of hand and allow things to die as they slip from our thoughts. Alternately, insights appear with time and exposure to things we might think are “unrelated” in the initial rush. There must be different characteristics, qualities and uses for closing / completing subjects like at Proctor and Gamble and the seemingly less directed open-for-input style?

I think you are right that an individual project needs completion–maybe because the feeling of being unresolved blocks new thoughts and new projects? Read in a writer’s guide once that we need to learn to trust we can come back to an interrupted thought stream and that’s true but it’s best used when other strategies fail and a full-time way to write.

Collaboration requires a certain graceful patience and expectation that everyone is doing what they can. A release of control maybe that sometimes can be frustrating.
