How do you create accountability and ownership in a family or organization?

I've brought my teams through a program based on Patrick Lencioni’s Five Dysfunctions of a Team. This reveals the main dysfunction that needs to be dealt with in each organization: Absence of Trust; Fear of Conflict; Lack of Commitment; Avoidance of Accountability and; Inattention to Results. Ownership is lacking when there is a problem with any of these areas (dysfunctions), but especially Avoidance of Accountability. Only through involvement and buy-in of the entire group to eliminate these dysfunctions will ownership in the process, family, and organization be built.
