Organization structure establishes the relationships between job positions and defines authority relationships. It groups similar jobs into departments under one manager to facilitate coordination. Job design specifies tasks and qualifications for each job and informs organization structure. Structure can be functional, grouping all work into major departments, or divisional, grouping activities and personnel by product line for expertise in each product. Span of control refers to the number of jobs one manager can supervise and delegation of authority allows managers to transfer decision making power to subordinates for large departments.
