I'm not sure the stimulation of creativity can be improved much with process and management. Just like bouncing off ideas, brainstorms etc. works best in-person. Physical contact is something that is hard to replicate or work around with technology. Everyone has experienced the difference between webconferencing and real person meeting and can tell that one has more weight than the other. Maybe VR could be of use here since it helps lift that imaginary barrier that gives weight to conversations.
