To handle increased complexity, which of the following is an appropriate method to adjust span of control?

• A. Reducing supervision and merging units.
• B. Delaying decisions and waiting for senior input.
• C. Expanding the ICS structure, creating branches, or adding supervisory personnel.
• D. Eliminating the planning function.

Answer: (C)

As complexity grows, you keep supervision effective by splitting the workload and adding layers of oversight. In the Incident Command System, a manageable span of control means a supervisor oversees a limited number of resources—typically 3 to 7, with about 5 as an ideal target. Expanding the ICS structure, creating branches, or adding supervisory personnel directly reduces the number of direct reports per supervisor, preserving clear communication, timely decisions, and safer, more coordinated action as the incident expands. Options that reduce supervision or merge units would widen the span of control, making supervision harder. Waiting for senior input delays decisions, which isn’t a structural solution. Eliminating the planning function removes essential guidance and coordination, degrading overall effectiveness.
