With ancient roots, the enneagram is a testing tool used to classify people into nine personality types and can be applied to every situation in which human interaction is involved. This comprehensive guide to using the enneagram in a corporate setting shows how the tests can help predict a person's reaction to situations encountered at work, help individuals to recognize their own qualities and pitfalls, and maximize communal efficiency. Detailed chapters demonstrate how the enneagram enables people to broaden their perspective and thus become more aware of others' viewpoints, feelings, and behavior while simultaneously increasing inter-personal effectiveness in managing, advising, and training others.
