If you have not had the chance to read the additional piece from Jim Collins on Good to Great and the Social Sectors, check it out.  As I read through this, he clearly and succinctly lays out the key factors critical to the overall health of the organization, and makes some interesting insights about the business world in connection to the social sector. 

Also, there are additional resources, videos, and assessments at www.jimcollins.com that I found to be partiularly helpful.
