"The Thin Book of Appreciative Inquiry" by Sue Annis Hammond

This thin and deceptively simple book is based on the assumption that if a team focuses on what went right whether it be during a meeting, implementing an initiative or running a school, then more good things will continue to happen.  Educators are good at talking about what doesn't work.  Appreciative Inquiry challenges us to focus on the 94% satisfied customers, rather than on the 6% unhappy.  Ask the 94% what we did that made them happy instead of problem solving by talking about what didn't work for the 6%.  The book explains how to do an inquiry process and what to do with the results. This is a great topic for a staff retreat.  It is non-threatening and yields positive results.
