This paper traces the history of Behavioural Science approaches in India. The paper examines the task centered, and identity centered approach to organization development. It differentiates between the institutional and structural modalities of organizations. The institutional modality has philosophy, mission, aim, direction and resource energy, tasks/targets, roles and performance and evaluation and rewards. These two are integrated with management control systems and sentient systems. If these are well integrated then wholesome organizations emerge with processes of coordination and control, sutonomy and discretion, organizational learning, renewal and regeneration and finally for individual a sense of belonging, mobilization of their resources and commitment. This further leads to organization processes of correspondence, convergence, coherence and congruence for task efficiencies. Indian organizations require IB processes so that organizations has individuals become dynamic and wholesome.
