Which role is primarily responsible for coordinating incident response activities in a FOSSE environment?

• A. On-call engineer
• B. Subject matter expert
• C. QA and Testing
• D. Incident Manager

Answer: (D)

Coordinating incident response activities requires a single lead who orchestrates actions, communications, and timelines during an incident. The Incident Manager fills this role by running the incident command, ensuring playbooks are followed, and keeping everyone aligned on priorities and progress. They organize the war room, assign and track action items, escalate as needed, and drive toward restoration while documenting the timeline for the post-incident review.

The on-call engineer focuses on hands-on remediation and system restoration. The subject matter expert provides specialized technical input in a particular domain. QA and Testing verifies fixes and validates that changes won’t reintroduce problems. None of these roles is primarily responsible for coordinating across teams and maintaining the incident timeline, which is why the Incident Manager is the best answer.
