Heinen, J. Stephen et Jacobson, Eugene, A Model of Task Group Development in Complex Organizations and a Strategy of Implementation, Academy of Management review , 1(4), 1976, pp. 98-111
An intervention strategy for development of an industrial work group is proposed from a four stage model of group development. The group is distinguished from therapy and sensitivity groups in terms of its problem solving task purpose. The model reflects emphasis upon task structure rather than affective relations. The four stages are: forming, differentiation, integration, and full maturity. Constraining factors are considered.
