Collective Intelligence Wins

My experience consulting and working in office environments in different countries tells me that the environment plays a very strong role in determining how productive the individual can be.

Some research from MIT seems to back up this hunch.

It goes further and says that the presence of women (or men) who have good social skills help the group’s performance to improve.

What I’d like to know if there’s been any research done to show the effect of higher skilled team members on group performance.  In other words, is there a collective intelligence that applies to time management skills?
