From this Delphi study among Dutch experts, the future of organization development (OD) emerges as a loosely coupled community of practice, linking very diverse members, professionals as well as scholars. One finds different priorities and values in this community, some of them even dilemmatic. The authors argue that diversity and complexity are strengths not weaknesses of a 'sustainable' OD. Referring to organizational concepts such as requisite variety and resilience, the authors stress that OD networks should, in the future more than in the past, make sure that a diverse set of ambitions can be discussed, promoted, fostered, accommodated and realized. © 2010 Taylor & Francis.
