Rather than put out yet a third edition of his two volumes on Organizational Development, Schein (management, Massachusetts Institute of Technology) has developed a third volume to the series, focusing on the interaction between consultants--from therapists and social workers to parents and friends--and their clients. He draws much of the material from the two previous volumes, but entirely rearranges it and assumes readers to be less knowledgeable about the profession.
