Fifty-four international academics and consultants, most based in the U.S., contribute 28 chapters about organizational development (OD)—the planned, systematic, and educationally-oriented change that is carried out for organizational improvement. Coverage includes essential background information about OD, the OD intervention process, different levels of intervention, and special issues in OD. The second edition features a more current change model, and, as with the first edition, is based on OD competency studies. The text has been thoroughly rewritten and updated throughout. It features exhibits, activities, instruments, and case studies, and contains PowerPoint slides and supplemental materials on an accompanying CD- ROM. For internal and external OD consultants, workplace learning and performance professionals, and managers and executives. Pfeiffer is an imprint of Wiley.
