The primary role of the Incident Commander during an incident affecting multiple systems is to establish a communication channel for responders. This role is crucial as it ensures that all team members involved in the incident response are aligned and informed about the current status, tasks, and strategies. Effective communication helps facilitate coordination among responders, which is essential for swift and efficient resolution of the incident.

The Incident Commander’s responsibility includes not only relaying information but also creating a structure for ongoing communication that enables quick decisions and updates, ultimately leading to better outcomes during high-pressure situations. By ensuring a clear communication channel, the Incident Commander helps prevent miscommunication and confusion, which could exacerbate the situation.

While managing communications with stakeholders and determining the root cause are important aspects of incident management, these tasks typically follow the establishment of the internal communication system. The postmortem analysis is usually conducted after the incident has been resolved, focusing on lessons learned and prevention strategies for future incidents. Thus, the emphasis on establishing communication channels makes it the most suitable primary role during the incident management process.
