NATIONAL INCIDENT MANAGEMENT SYSTEM
National Incident Management System (NIMS) is the culmination of more than 40 years of efforts to improve interoperability in incident management. This work began in the 1970s with local, state, and Federal agencies collaborating to create a system called Firefighting Resources of California Organized for Potential Emergencies (FIRESCOPE). FIRESCOPE included ICS and the Multiagency Coordination System (MACS). In 1982, the agencies that developed FIRESCOPE and the National Wildfire Coordinating Group (NWCG) created the National Interagency Incident Management System (NIIMS), in part to make ICS guidance applicable to all types of incidents and all hazards. Under Homeland Security Presidential Directive #5 (February 2003), the Federal government created the National Incident Management System (NIMS). This system directed the creation of a comprehensive, national approach to incident management. Recognizing the value of these systems, communities across the Nation have adopted NIMS. The most current revision of NIMS was released in October 2017.
NIMS Management Characteristics
The following characteristics are the foundation of incident command and coordination under NIMS and contribute to the strength and efficiency of the overall system:
Common Terminology
EXTRACTED FROM - E/L/G 0300 Intermediate Incident Command System for Expanding Incidents, ICS 300
Every incident should have an action plan; however, not all incidents need written plans. The necessity for written plans depends on incident complexity, command decisions, and legal requirements. Formal IAPs are not always developed for the initial operational period of no-notice incidents. However, if an incident is likely to extend beyond one operational period, becomes more complex, or involves multiple jurisdictions and/or agencies, preparing a written IAP becomes increasingly important to maintain unity of effort and effective, efficient, and safe operations.
Staff in EOCs also typically conduct iterative planning and produce plans to guide their activities during specified periods, though these are typically more strategic than IAPs.
Manageable Span of Control
Maintaining an appropriate span of control helps ensure an effective and efficient incident management operation. It enables management to direct and supervise subordinates and to communicate with and manage all resources under their control. The type of incident, nature of the task, hazards and safety factors, experience of the supervisor and subordinates, and communication access between the subordinates and the supervisor are all factors that influence manageable span of control.
The optimal span of control for incident management is one supervisor to five subordinates; however, effective incident management frequently necessitates ratios significantly different from this. The 1:5 ratio is a guideline, and incident personnel use their best judgment to determine the actual distribution of subordinates to supervisors for a given incident or EOC activation.
Incident Facilities and Locations
Depending on the incident size and complexity, the Incident Commander, Unified Command, and/or EOC director establish support facilities for a variety of purposes and direct their identification and location based on the incident. Typical facilities include the Incident Command Post (ICP), incident base, staging areas, camps, mass casualty triage areas, points-of-distribution, and emergency shelters.
Comprehensive Resource Management
Resources include personnel, equipment, teams, supplies, and facilities available or potentially available for assignment or allocation. Maintaining an accurate and up-to- date inventory of resources is an essential component of incident management. Section II, the Resource Management component of this document, describes this in more detail.
Integrated Communications
Leadership at the incident level and in EOCs facilitates communication through the development and use of a common communications plan, interoperable communications processes, and systems that include voice and data links. Integrated

communications provide and maintain contact among and between incident resources, enable connectivity between various levels of government, achieve situational awareness, and facilitate information sharing. Planning, both in advance of and during an incident, addresses equipment, systems, and protocols necessary to achieve integrated voice and data communications. Section IV, the Communications and Information Management component of this document, describes this in more detail.
Establishment and Transfer of Command
The Incident Commander or Unified Command should clearly establish the command function at the beginning of an incident. The jurisdiction or organization with primary responsibility for the incident designates the individual at the scene responsible for establishing command and protocol for transferring command. When command transfers, the transfer process includes a briefing that captures essential information for continuing safe and effective operations, and notifying all personnel involved in the incident.
Unified Command
When no one jurisdiction, agency or organization has primary authority and/or the resources to manage an incident on its own, Unified Command may be established. In Unified Command, there is no one “commander.” Instead, the Unified Command manages the incident by jointly approved objectives. A Unified Command allows these participating organizations to set aside issues such as overlapping and competing authorities, jurisdictional boundaries, and resource ownership to focus on setting clear priorities and objectives for the incident. The resulting unity of effort allows the Unified Command to allocate resources regardless of ownership or location. Unified Command does not affect individual agency authority, responsibility, or accountability.
Chain of Command and Unity of Command
Chain of command refers to the orderly line of authority within the ranks of the incident management organization. Unity of command means that each individual only reports to one person. This clarifies reporting relationships and reduces confusion caused by multiple, conflicting directives, enabling leadership at all levels to effectively direct the personnel under their supervision.
Accountability
Effective accountability for resources during an incident is essential. Incident personnel should adhere to principles of accountability, including check-in/check-out, incident action planning, unity of command, personal responsibility, span of control, and resource tracking.
Dispatch/Deployment

Information and Intelligence Management
The incident management organization establishes a process for gathering, analyzing, assessing, sharing, and managing incident-related information and intelligence. Information and intelligence management includes identifying essential elements of information (EEI) to ensure personnel gather the most accurate and appropriate data, translate it into useful information, and communicate it with appropriate personnel.
Note that in In NIMS, “intelligence” refers exclusively to threat-related information developed by law enforcement, medical surveillance, and other investigative organizations.
ICS HISTORY AND FEATURES
Incident Command System
ICS is a standardized approach to the command, control, and coordination of on-scene incident management that provides a common hierarchy within which personnel from multiple organizations can be effective. ICS specifies an organizational structure for incident management that integrates and coordinates a combination of procedures, personnel, equipment, facilities, and communications. Using ICS for every incident helps hone and maintain skills needed to coordinate efforts effectively. ICS is used by all levels of government as well as by many NGOs and private sector organizations. ICS applies across disciplines and enables incident managers from different organizations to work together seamlessly. This system includes five major functional areas, staffed as needed, for a given incident: Command, Operations, Planning, Logistics, and Finance/Administration. A sixth ICS Function, Intelligence/ Investigations, is only used when the incident requires these specialized capabilities.
Incident Complexity, Complex Incidents and Incident Complex
Incident Complexity is the combination of involved factors that affect the probability of control of an incident. Many factors determine the complexity of an incident, including, but not limited to, area involved, threat to life and property, political sensitivity, organizational complexity, jurisdictional boundaries, values at risk, weather, strategy and tactics, and agency policy. Incident complexity is considered when making incident management level, staffing, and safety decisions.
Incident complexity is assessed on a five-point scale ranging from Type 5 (the least complex incident) to Type 1 (the most complex incident).
Various analysis tools have been developed to assist consideration of important factors involved in incident complexity. Listed below are some of the factors that may be considered in analyzing incident complexity:

Complex Incidents are larger incidents with higher incident complexity (normally Type 1 or Type 2 incidents) that extend into multiple operational periods and rapidly expand to multijurisdictional and/or multidisciplinary efforts necessitating outside resources and support.
According to NIMS 2017, Incident Complex refers to two or more individual incidents located in the same general area and assigned to a single Incident Commander or Unified Command.

Overall Organizational Functions
ICS was designed by identifying the primary activities or functions necessary to effectively respond to incidents. Analyses of incident reports and review of military organizations were all used in ICS development. These analyses identified the primary needs of incidents.
As incidents became more complex, difficult, and expensive, the need for an organizational manager became more evident. Thus, in ICS, and especially in larger incidents, the Incident Commander manages the organization and not the incident.
In addition to the Command function, other desired functions and activities were to:

ICS – Who Does What?
Incident Commander
The Incident Commander is technically not a part of either the General or Command Staff. The Incident Commander is responsible for:

Operations Section Chief Responsibilities
The Operations Section Chief is responsible for managing all tactical operations at an incident. The Incident Action Plan (IAP) provides the necessary guidance. The need to expand the Operations Section is generally dictated by the number of tactical resources involved and is influenced by span of control considerations.
Major responsibilities of the Operations Section Chief are to:
Planning Section Chief Responsibilities
The Planning Section Chief is responsible for providing planning services for the incident. Under the direction of the Planning Section Chief, the Planning Section collects

Major responsibilities of the Logistics Section Chief are to:
Finance/Administration Section Chief Resposibilities
The Finance/Administration Section Chief is responsible for managing all financial aspects of an incident. Not all incidents will require a Finance/Administration Section. Only when the involved agencies have a specific need for finance services will the Section be activated. Major responsibilities of the Finance/Administration Section Chief are to:

Intelligence/Investigations Function
The collection, analysis, and sharing of incident-related information are important activities for all incidents. Typically, staff in the Planning Section are responsible for gathering and analyzing operational information and sharing situational awareness, and staff in the Operations Section are responsible for executing tactical activities.
However, some incidents involve intensive intelligence gathering and investigative activity, and for such incidents, the Incident Commander or Unified Command may opt to reconfigure intelligence and investigations responsibilities to meet the needs of the incident. This may occur when the incident involves a criminal or terrorist act and/or other non-law-enforcement intelligence/investigations efforts such as epidemiological investigations.
The purpose of the Intelligence/Investigations function is to ensure that intelligence and investigative operations and activities are properly managed and coordinated to:
The Incident Commander or Unified Command makes the final determination regarding the scope and placement of the Intelligence/Investigations function within the command structure. The intelligence/investigations function can be incorporated as an element of the Planning Section, in the Operations Section, within the Command Staff, as a separate General Staff section, or in some combination of these locations.
