Summary of the book by Patrick Lencioni. Clients love this simple model of teamwork. The book is written as a fable and tedious to read. This book summary captures the essence of the team model. The model can be used as a diagnostic to assess what is keeping a team from high performance. In my experience, top teams operate with a lot of personal and expertise trust. This trust allows the team to have healthy conflict, commit to plans, and hold each other accountable.
