In today's fast-paced business world, there is rapid and continuous change in organizational direction and guidance. To stay ahead, many contemporary managerial practices in leadership, performance appraisal, and executive selection require serious revision. I/O consultants increasingly need to focus on sound organizational diagnosis to successfully modify executive maladaptive behavior. By applying psychodynamic theory to the workplace, consultants can more effectively assess and correct dysfunctional organizational practices in evaluating, supervising, and managing employees.For over 50 years, Harry Levinson, a pioneer in the field of organizational consulting psychology, has applied his extensive clinical expertise to the understanding of organizational assessment and intervention. In this volume, the editors present 18 of Levinson's landmark contributions that explore how and why consultants diagnose organizational and managerial pathology. These chapters showcase Levinson's astute clinical and counseling insights on organizational diagnosis, leadership, consultation, and stress. I/O and business management consultants will learn how to expertly apply these techniques to various organizational problems, as well as enhance their own self-reflective awareness.
