Organization transformation (OT) is emerging as either an extension of organization development (OD) or a new discipline. OT can occur in response to major environmental or technological changes requiring modifications to business strategy, culture, structures, and processes. The historical development of OD includes innovations in applying laboratory training insights to organizations, survey research and feedback methodology, the emergence of action research, and sociotechnical and socioclinical approaches. Practitioners are now focusing on concepts like second generation OD and organizational transformation.
