This document discusses the evolution of management thought through five approaches: universal process, operational, behavioral, systems, and contingency. The universal process approach views core management functions as the same across organizations, exemplified by Henry Fayol's 14 principles of management. The operational approach aims to promote efficiency through scientific and systematic methods. The behavioral approach focuses on understanding and addressing human needs. The systems approach views organizations holistically as interdependent systems. The contingency approach contends there is no single best way to manage and the effectiveness of techniques depends on the situation.
