Not everything is meant to be measured in terms of cycle-time, and not everything is task oriented.  The creative process is a perfect example of this.  Assigning the new breakthrough marketing campaign with a clear-cut process with assigned tasks just isn’t going to provide the breadth of insight needed for such right-brained thought.

Sure, collaboration at the ideation stage, using tools like SharePoint makes a lot of sense.  But doing a workflow for this is probably overkill.  There really isn’t a well defined business process for this (at least not that I’m aware of).  Sure there a generalized steps in the process, but innovation and creativity are key components of this that are managed in a stepwise manner.  I couldn’t imagine someone asking our SharePoint Workflow Factory to develop a system for doing the creative aspects of a marketing campaign.
