The document discusses several key concepts related to organizing and organization structure: 1. Organizing involves deploying organizational resources to achieve strategic goals through division of labor and coordination of tasks through formal lines of authority. 2. Organization structure includes the formal tasks assigned to roles, formal reporting relationships, and systems to coordinate employees across departments. 3. Span of control refers to the number of employees reporting to a supervisor, which determines whether an organization's structure is tall versus flat. Wider spans of control and fewer hierarchical levels result in a flatter structure.
