In very large organizations there is often more than one group of users managing Major Incidents, because of the different departmental communication needs and knowledge of the corresponding area of responsibility. The responsibility could be for example based on either the resolver organization or for specific services. How can this concept fit here? Everything seems to be set up to have one Major Incident Managers group. If no on-call scheduling is in place this could, for example, mean that 80 Major Incident Managers get notified about one Major Incident Candidate, which can be quite annoying if there are many candidates.
