The general argument for organization development asserts that a planned and systematic application of principles and practices in behavior science is required for organization development. It assumes that collaboration and cooperation is a better way to solve problems in organization and increase both organizational efficiency and individual well-being than bargaining and politics. Contrary to the above argument and assumption, this article asserts that a planned teaching and learning, and reform as a process of organizational development will bring about some political problems involving choice and decision, gain and loss, conflict and bargain in both individual and collective behaviors. It also maintains that the process will more easily reveal various characteristics of powers in organization: their multiplicity, their complexity and interplay, their unequal distribution, their volatility, their relevance for organizational structures, their being subjectively perceived, their limitation, and their being non-zero-sum game. In addition, it critically examines the insufficiency of the fundamental assumptions of the theories of organization development on the dimensions of the individual. the organization, diagnosis and prescription. Finally, on the basis of the claim that the political approach is more important and useful than that of neutral organization development, this author suggests that members of organizations should play the role of seekers, holds and exercisers of power and use the ethical-political organizational behaviors to enhance both individual and organizational efficiency.
