Major incident manager\[mim\_manager\]

</td><td>

A major incident manager can:-   Initiate the major incident process by assessing and approving major incident candidates or creating a major incident.
-   Reject a major incident candidate.
-   Demote a major incident after it is accepted so that the incident can be handled as a regular incident.
-   Maintain the ownership and accountability for the life cycle of the incident.
-   Identify the users and groups to be involved in the resolution activities.
-   Create ad hoc communication plans and tasks.
-   Edit a communication plan that is attached to a major incident.
-   Close a major incident.

-   sn\_incident\_write
-   sn\_problem\_write
-   sn\_change\_write
-   sn\_request\_write
-   itil

 **Note:** Starting with Brazil, for zBoot instances, the major incident manager \[major\_incident\_manager\] role no longer inherits the itil role. Instead, it inherits the sn\_incident\_write, sn\_problem\_write, sn\_change\_write, and sn\_request\_write granular roles from the ITSM Roles plugin \(com.snc.itsm.roles\).

For upgraded instances, the itil role remains inherited. Additionally, the sn\_incident\_write, sn\_problem\_write, sn\_change\_write, and sn\_request\_write granular roles are added if the ITSM Roles plugin \(com.snc.itsm.roles\) is installed.
