Which of the following state values is NOT used in an incident's lifecycle?

In the context of an incident's lifecycle within IT Service Management, the states typically represent the different phases an incident can go through from the moment it is reported to its resolution.

The state "In Progress" indicates that work is actively being done to resolve the incident, while "Resolved" signifies that the incident has been addressed and a solution has been implemented. The state "Canceled" denotes that the incident has been terminated for some reason, perhaps determined as a duplicate or no longer necessary.

However, "Pending Approval" is not generally a state used in the incident lifecycle. It more commonly pertains to change management processes where actions taken may require approval before they can be executed. In the incident lifecycle, the primary focus is on tracking incidents through stages like identification, investigation, resolution, and closure, rather than managing approval processes.

Thus, "Pending Approval" does not align with the standard states of incident management, making it the correct choice as the state value that is not used in an incident’s lifecycle.
