Predicting the Resource Needs of an Incident
Predicting the resource needs of an incident to determine the appropriate management structure is referred to as complexity analysis.
In the context of the Incident Command System (ICS) and emergency management, this process is vital for ensuring that the incident is handled by a team with the right level of training, experience, and specialized equipment.

What is Complexity Analysis?
Complexity analysis is the continuous process of evaluating the characteristics of an incident to determine the management requirements. It involves assessing various “complexity factors” such as the size of the affected area, the potential for life safety threats, and the political or economic impact of the event.
Pro Tip: Complexity analysis is not a one-time event. As an incident grows or stabilizes, the complexity level changes, which may require a “transition of command” to a higher or lower level Incident Management Team (IMT).
How Complexity Determines Management Structure
Under the National Incident Management System (NIMS), incidents are categorized into five types based on their complexity:
- Type 5: Small, localized incidents (e.g., a single vehicle accident) handled by a few local resources.
- Type 4: Command and general staff functions are activated only if needed; usually limited to one operational period.
- Type 3: Significant local incidents requiring multiple resources and an extended duration.
- Type 2: National or state-level significance; requires a dedicated Incident Management Team.
- Type 1: The most complex incidents (e.g., major hurricanes or large-scale terrorist attacks) requiring national resources.
Comparison Table: Complexity Analysis vs. Resource Typing
It is easy to confuse these two terms, but they serve different functions in incident management:
| Feature | Complexity Analysis | Resource Typing |
|---|---|---|
| Primary Goal | Determine management structure (Type 1-5) | Categorize equipment and personnel |
| Focus | The situation/incident as a whole | Specific assets and their capabilities |
| Key Variable | Potential for escalation and risk | Minimum requirements for a resource |
| Result | Selection of Incident Commander level | Selection of specific tools or crews |

Frequently Asked Questions
1. Who is responsible for performing complexity analysis?
Initially, the First Arriving Officer or the initial Incident Commander performs the analysis. As the incident grows, this responsibility stays with the current Incident Commander to determine if they need to request a more advanced management team.
2. What are common “Complexity Factors”?
Common factors include hazardous materials involvement, weather conditions, the number of different agencies involved, and the legal or jurisdictional boundaries crossed.
3. Why is this process important for safety?
If the management structure is too small for a complex incident, communication breaks down and safety risks increase. Conversely, a structure that is too large for a simple incident wastes valuable resources.
