Coordination is the practice of organizing people and teams so that response to an incident is orderly rather than chaotic. It establishes who is in charge, what each person is responsible for, and how work and information pass between teams, so that many contributors act as one coherent effort.

Within the Response phase, coordination is the connective tissue that holds the other activities together. Triage, investigation, containment, eradication, and communication each involve different skills and often different teams, and without coordination they can collide, duplicate effort, or leave gaps. A clear command structure ensures decisions are made, actions are sequenced, and nothing critical falls between roles.

In practice, coordination often uses an incident command model that names an incident commander to lead and defines supporting roles for technical work, communication, and record-keeping. The commander sets priorities, tracks status, and manages handoffs as shifts change or specialists join and leave. Clear roles reduce confusion under pressure, and a maintained record of actions and decisions supports both the live response and the later review. Rehearsing these structures before an incident, through exercises, makes coordination dependable when a real event demands it.
