How Many NIMS Management Characteristics Are There?

The National Incident Management System (NIMS) is a comprehensive framework developed by the Federal Emergency Management Agency (FEMA) to provide a consistent approach to incident management in the United States. It encompasses various components, including the Incident Command System (ICS), Multiagency Coordination System (MACS), and Public Information System (PIS). NIMS is designed to be flexible and adaptable, applicable to incidents of all sizes and complexities, including natural disasters, accidents, and acts of terrorism.

Within the NIMS framework, there is a set of fundamental principles and practices known as NIMS management characteristics. These characteristics serve as the building blocks of the NIMS Incident Command System and provide a consistent way to organize and communicate actions during an incident response. This article will explore the 14 NIMS management characteristics and their significance in incident management.

1. Common Terminology

The use of common terminology is one of the key NIMS management characteristics. It ensures that all responders involved in an incident use the same language, including acronyms, definitions, and descriptive terms. This shared understanding facilitates effective communication and coordination among multiple agencies and organizations. By speaking a shared language, responders can align their efforts, objectives, and strategies, minimizing confusion and enhancing overall incident response.

2. Modular Organization

Modular organization is another essential NIMS characteristic. It involves organizing personnel into groups or teams that can function independently yet seamlessly integrate into a unified response effort. These teams can range from small groups of two to large units comprising hundreds of individuals, depending on the incident’s scale and complexity. The modular structure allows for flexibility and adaptability, enabling responders to adjust and allocate resources as needed quickly. It also promotes efficient resource sharing and collaboration between teams, optimizing the use of available assets.

3. Management by Objectives

NIMS emphasizes management by objectives as a guiding principle. This means that emergency responders establish clear objectives and develop plans to achieve them. By setting goals and creating actionable strategies, all personnel involved in the incident gain a shared understanding of their responsibilities and the necessary steps to accomplish the mission. Management by objectives helps maintain focus, prevent distractions, and ensure that actions taken during the response align with the overall incident objectives.

4. Incident Action Planning

Incident action planning is a critical NIMS characteristic that involves developing a comprehensive plan to guide the response effort. The incident action plan outlines the incident’s objectives, identifies required resources, assigns tasks to personnel, and establishes timelines for task completion. It serves as a roadmap for incident management, providing a systematic approach to coordinate actions and allocate resources effectively. While the plan should be flexible to adapt to evolving circumstances, it provides a structured framework for all responders.

5. Manageable Span of Control

The concept of a manageable span of control is integral to NIMS. It addresses the need for adequate supervision and oversight during incident response. Each supervisor or manager should be responsible for limited personnel and resources to maintain control, ensure clear communication, and provide guidance and support. A manageable span of control prevents overwhelming supervisors and allows for efficient coordination and decision-making. It enables supervisors to provide timely feedback, enhance performance, and maintain situational awareness.

6. Incident Facilities and Locations

NIMS requires the identification and proper management of incident facilities and locations. This includes establishing command posts, staging areas, and other facilities where respondents can gather, organize, and deploy resources. Incident facilities should be equipped with the necessary resources, such as communication equipment, medical supplies, and food, to support the response efforts effectively. Proper management of incident facilities and locations enhances coordination, accessibility, and safety throughout the incident response.

7. Comprehensive Resource Management

Comprehensive resource management is a fundamental NIMS characteristic. It involves effectively managing all resources required to respond to an incident. Resources can include personnel, supplies, equipment, and any other assets necessary for an efficient response. Resource management encompasses resource coordination between different agencies and organizations, ensuring the sharing and allocation of resources where they are most needed. It also involves assessing the skills and training of personnel to ensure they are appropriately matched with the tasks at hand.

8. Integrated Communications

Effective communication is vital for successful incident management. NIMS emphasizes establishing integrated communications systems and protocols that enable seamless information exchange among responders. Standardized terminology, communication channels, and protocols promote clear and accurate communication, reducing the risk of misunderstandings or conflicting information. Integrated communications support coordination, decision-making, and situational awareness across all levels of the incident response structure.

9. Establishment and Transfer of Command

NIMS provides procedures for the establishment and transfer of command during incident management. This ensures a transparent chain of command and facilitates effective leadership transitions as the incident evolves. The incident commander is responsible for managing the incident and may transfer power to another qualified individual if necessary. Establishing and sharing command maintains continuity, clarifies lines of authority, and ensures all personnel know who is in charge at any given time.

10. Unified Command

The unified command structure is a critical component of NIMS management. It combines the various agencies, organizations, and resources involved in incident response under a single coordinated effort. The unified command structure designates an incident commander with overall authority and responsibility for managing the incident. This individual coordinates all aspects of the response, ensuring effective collaboration and decision-making among all involved parties.

11. Unity of Command and the Chain of Command

The chain of command is an essential element of NIMS, providing a hierarchical structure that outlines roles, responsibilities, and reporting relationships. Each incident management team member has a specific role within the chain of command, ensuring clear lines of authority and accountability. Unity of command further reinforces this structure, requiring all personnel involved in the incident to report directly to the commander. The chain of command and unity of command facilitate coordinated and efficient decision-making, optimizing incident response efforts.

12. Accountability

Accountability is a critical NIMS management characteristic, ensuring individuals are responsible for their actions during an incident. Through the incident management system, accountability is tracked, allowing for the identification of areas that require additional training or improved procedures. Accountability promotes the efficient use of resources, timely task completion, and overall effectiveness in incident response. It also supports learning and improvement by identifying strengths and weaknesses in the management and execution of response activities.

13. Dispatch/Deployment

Dispatching and deploying personnel, equipment, and resources are central to effective incident management. NIMS emphasizes the need for well-coordinated processes to promptly ensure that the right personnel and resources are dispatched to the incident scene. A transparent chain of command and established communication protocols facilitate efficient dispatch and deployment, ensuring that personnel are available when and where they are needed most.

14. Information and Intelligence Management

Information and intelligence management involve gathering, evaluating, analyzing, and sharing information to support informed decision-making during incident response. This includes exchanging critical information among agencies and organizations involved in the response effort. Sharing information enhances situational awareness, enables collaborative decision-making, and facilitates a more effective and coordinated response. Information gathered during an incident can contribute to future prevention, mitigation, and improved training and procedures.


In conclusion, the National Incident Management System (NIMS) encompasses 14 essential management characteristics that are the foundation for effective incident management. These characteristics provide a standardized framework for organizing and communicating actions during incident response, regardless of the agency or organization involved. Responders can enhance coordination, optimize resource utilization, and improve overall incident outcomes by adhering to these principles. Understanding and implementing the NIMS management characteristics are crucial for building a resilient and effective incident management system.
