A refinement of individual coaching is for the coach to work with both the individual and his or her work associates. The coach solicits feedback from the group members and involves them in helping the manager improve. For example, the coach might tell team members to assert their rights when the manager throws a temper tantrum or makes unreasonable demands. The coach might also work with the superiors or peers of the person being coached. Coach Marshall Goldsmith says, "My success rate as a coach has improved dramatically, as I've realized that people's getting better is not a function of me; it's function of the person and the people around the person.
