What does the diagram illustrate in relation to major incidents?

The diagram illustrates the threshold for escalating a minor incident. This means it visually represents the criteria or conditions under which a minor incident should be reclassified and escalated to a major incident. By mapping out these thresholds, the diagram helps responders recognize the severity of incidents more clearly and take appropriate actions based on predefined criteria.

Understanding when to escalate is crucial in incident management, as it allows teams to allocate resources effectively and address significant issues promptly. The clear delineation of these thresholds helps ensure that minor issues do not obstruct the handling of more critical incidents.

In contrast, other options refer to different aspects of incident management. The communication flow during an incident focuses on how information is shared among stakeholders and is crucial for effective coordination, but it is not what the diagram specifically illustrates. Common pitfalls in incident resolution highlight frequent mistakes that organizations might encounter, but this is not related to threshold decisions. The process for resolving minor incidents outlines the steps to manage less severe issues and is distinct from determining when those issues should escalate.
