Span of Control refers to the number of subordinates that a manager or supervisor can directly control or supervise effectively. It is a key concept in designing organizational structure and influences how tall (many levels) or flat (fewer levels) the hierarchy of an organization will be.

Factors Determining Span of Control
1. Nature of Work
Repetitive or routine tasks require less supervision → wider span.
Complex or varied tasks require more guidance → narrower span.
2. Manager’s Capability
Skilled and experienced managers can handle more subordinates.
3. Employee Competency
Skilled, trained employees require less supervision.
4. Use of Technology
Tools like project management software reduce the need for close supervision.
5. Geographical Proximity
When subordinates are located in the same area, a wider span is feasible.
6. Level of Management
Top-level managers generally have a narrower span than middle or lower-level managers.
7. Degree of Delegation
If authority is well-delegated, one manager can oversee more employees.
8. Communication Systems
Effective systems enable managers to supervise more people.

Conclusion
The optimal span of control depends on the balance between control and efficiency. Organizations must analyze their tasks, managerial strength, and workforce capacity to determine whether a narrow or wide span will serve them best.
