Belbin's theory of Team Roles (which is one of the few lenses that doesn't strike me as complete BS) breaks people in to a number of categories: Plants (idea's people), Resource Investigators (starters), Co-ordinators (competent PA), Shapers (classical good non-technical PMs who take the project through from soup to nuts), Monitor Evaluators (critics, QA folk), Teamworkers (the quite guy who sorts out fights), Implementers (Intrepreneurs, who set up the bug tracking system that everyone agrees is a good idea), Completer Finishers (perfectionists), and Specialists (what tell you that they read an article 20 years ago that showed how to do it better in 3 lines of code). Google seems to want "Plants", who are great people, but too many cooks spoil the broth.
