Creative networkart or science or business. It is never larger than about a dozen people who may move from one project to another as a troupe or team.
They have only a few goals at at time, and never more than one major goal. Each person plays a tightly or loosely defined role in the network. For instance to make a movie you need a writer, director, producer and actors, and maybe also costumer, cameraman (if the director can't do it all), audio engineer, film editor, if the project is big enough and the schedule tight enough. Very often the roles and timing are determined by a power network (say the bank or studio that funds the project). However, the creative control remains within the small creative network.
