Managing effort in volunteer organizations
One of the challenges in getting work done in volunteer outfits (say, churches) is that everyone is, well, a volunteer. They volunteered in and they can volunteer out. Rick Warren (no link) writes of the "Seven Principles for Every Church Project," and I think they would apply to secular, volunteer organizations as well. The principles are:
Participation: Work with those who want to work, ignore the ones who don't.
Keep it simple
Delegate
Motivate
Administrate
Appreciate
