Possible Answers:

  1. Incident Command System
  2. Emergency Operations Center (EOC)
  3. MAC Groups
  4. Joint Information System (JIS)

The Correct Answer:

3. MAC Groups make cooperative multi-agency decisions.


MACS stands for Multiagency Coordination Systems. This system generally refers to the four NIMS Command and Coordination processes or systems. These systems are  listed below:

  • The Incident Command System: This is a standardized approach on the incident site. ICS enables to create of a unified organizational structure that corresponds to the complexity and needs of occurrences.
  • Emergency Operations Centers or EOCs assist on-scene event management through multiagency cooperation and workforce.
  • MAC Groups are generally high-level multiagency coordinating bodies that provides planning and resource distribution assistance to ICS and EOCs.
  • The Joint Information System is the last commanding and control component. The Joint Information System guarantees that public messaging from the ICS, EOCs, and MAC Group is organized and reliable.

MACS or Multiagency Coordination System is intended to make multiagency coordination easier, and also allow all federal agencies or fields to collaborate more quickly and productively. When workers from multiple agencies engage in tasks like readiness, protection, reaction, rehabilitation, and prevention, multiagency cooperation exists routinely.

More precisely, MACS’ principal mission is to coordinate efforts in the field scale and prioritize the incident requests for crucial or conflicting resources, hence improving field operations management. Personnel, processes, procedures, marketing practices, and interactions are all part of MACS, that are combined into a single system. When resources requirements surpass the internal capacity, then the EOCs can assist MACS operations and offer assistance to Unified command, Area Command, or Incident Command.

The MAC Group is NIMS’s off-site event management system. The main functions of MAC groups are listed down below:

  • Group act as the policy level body.
  • The group is responsible for supporting resource allocation and prioritization.
  • The group is responsible for making multi-agency decisions by coordinating with other team members.
  • Responsible for deciding the appointed and elected officials.
  • Responsible for managing the incident in association with incident command functions.

Participants of the MAC Group are usually agency managers, and other designees that may be  involved in several organizations in the incident site..  Members of non-governmental organizations, like corporations and volunteer organizations, may be included in the MAC Group.
