For many people, boards and committees go hand-in-hand in the structure of a non-profit organization. Committees though, are one of the elements where assumptions often rule on what ones to have, not always to good effect.
What I will try to do is to sketch out what board committees non-profits ought to put in place, ones to be careful setting up, and what steps, like written terms of reference, can help to make them effective. Perhaps I can take the guesswork out of the picture.
