In logistics and materials management, organizational structure plays an important role in defining authority, responsibility, coordination, and decision-making processes. Two common types of organization structures used in logistics functions are Line organization and Staff organization. Both structures have different approaches to managing operations, authority relationships, and support activities. A Line organization structure is a simple and traditional form of organizational arrangement where authority flows directly from top management to lower levels. In this structure, managers have direct control over their subordinates, and each employee is responsible for reporting to a single superior. In logistics, a line structure may include positions such as logistics manager, warehouse supervisor, transportation supervisor, and operational staff, where each level has clear responsibility for executing activities. The major feature of a Line organization is direct authority.
