This report provides a comprehensive analysis of organizational structure, delving into its key elements and the contributions of management theorists. It examines concepts such as work specialization (Adam Smith), departmentalization (Gulick and Urwick), chain of command (Fayol), span of control (V.A. Graicunas), centralization vs. decentralization (Maurice Block), and formalization (Lawrence B. Mohr). The report explores how these elements are applied in real-world companies like Toyota, Coca-Cola, Unilever, and Nestle, providing insights into their organizational structures. Furthermore, it discusses contingencies for the organizational environment, including overall tactics, organization size, and technical developments. The report concludes with recommendations for strengthening organizational structures and improving internal communication and transparency.
