Agreed.  In the IBM paper, the action team (those who implement solutions) is
3-4 people for organizations of 20-50 or 8-10 for larger organizations
of 200-250.  These people spend about 10% of their time on this task
-- this comes out to less than 1% of the total people-time.  People
spend an average of 24 person-hours per action -- they're not
implementing monolithic silver bullets.
