The Five Dysfunctions of a Team is a must read for anyone that works in a close team environment. Patrick Lencioni uses a fictional story to lay the groundwork for a model that applies to any team. The story is engaging and keeps the readers attention as we learn about how to create a functional team.
The model addresses Trust, Conflict, Commitment, Accountability, and Results. Each area is interrelated and builds on each other. For example, without trust, a team probably won't be able to have healthy conflict which is necessary to create commitment through buy in and clarity of the issues. Without commitment, it is unlikely team members will allow themselves to be held accountable and without accountability is unlikely the team will see results. A simple but extremely helpful model for improving a team.
I would highly recommend this book to anyone looking to build a stronger results oriented team.
