This document provides an overview of classical and modern organization theory as applied to health care organizations. It discusses several theories of organization including scientific management, administrative management, behavioral, systems, and contingency theories. Scientific management theory focuses on standardization, time studies, and dividing work responsibilities. Administrative theory examines formal structure, rules, and principles of management. Behavioral theory emphasizes human factors like motivation, leadership, and group dynamics. Systems theory views organizations as goal-oriented systems, while contingency theory contends there is no single best way to manage and the approach must fit the situation. The theories provide frameworks for functions like management structures, performance evaluation, process standardization, and adapting to changing environments in health care.
