Management guru Isaac Adizes believes that one person is not capable of fulfilling all four roles necessary for effective management of an organization: being a producer of results, an administrator, an entrepreneur, and an integrator. The place of the non-existent “ideal manager” should be taken by a complementary team of managers, each member of which knows how to perform one of the roles perfectly, and masters the others at an acceptable level. At the same time, it is important that the team does not have leaders who concentrate on only one role, completely forgetting about the others. Such distortions make management ineffective and jeopardize the fate of the organization. The book will teach you to evaluate and improve your management style, the management styles of colleagues and subordinates, and understand how to form a complementary team of leaders. It is aimed at management specialists and managers of any companies and organizations; it will also be of interest to a wide audience.
