What element is crucial for post-incident operations according to DSAC Annex B?

The element that is crucial for post-incident operations according to DSAC Annex B is operating under emergency protocols. This focus is vital because after an incident occurs, organizations need to ensure that they have a structured and effective response in place to manage the situation, mitigate further risks, and restore normal operations as quickly as possible. Emergency protocols provide the guidelines and procedures that help teams respond effectively to the incident, ensuring that everyone involved knows their roles and responsibilities. This approach minimizes confusion and allows for a more coordinated recovery effort, increasing the likelihood of a successful resolution to the incident.

The other options, while important in their respective contexts, do not directly relate to the immediate and operational needs following an incident. For instance, comprehensive financial analysis is more relevant for strategic planning rather than immediate operational response. Staff social events can improve morale but are not critical for incident management. Market expansion strategies are forward-looking approaches that pertain to organizational growth and can be addressed after the immediate post-incident response is managed.
