Which field-tested management characteristic of ICS invokes that supervisors must be able to adequately supervise and control subordinates?

• A. Integrated Communications
• B. Comprehensive Resource Management
• C. Manageable Span of Control
• D. Unified Command

Answer: (C)

Span of control is the number of individuals or resources a supervisor can effectively supervise at an incident. This field-tested management characteristic ensures that supervision, direction, and communications stay clear and timely. When the span of control is kept within a practical range, supervisors can actively oversee subordinates, make faster decisions, and keep tasks on track, which is essential for safety and efficiency. In ICS, a typical range is about 3 to 7 direct reports, with around five being common, adjusted for complexity and risk. That’s why this option best fits the idea of adequately supervising and controlling subordinates.

Integrated Communications relates to ensuring reliable, redundant communications across the incident organization, not the number of subordinates a supervisor can manage. Comprehensive Resource Management deals with planning, acquiring, and tracking resources. Unified Command is about coordinating across multiple agencies or jurisdictions. The concept here centers on keeping supervision span manageable to maintain effective control.
