Which stage is NOT part of the Problem Management lifecycle?

The correct answer is Service Request Management because it is not part of the Problem Management lifecycle. Problem Management focuses specifically on identifying, analyzing, and resolving the root causes of incidents to prevent their recurrence. The lifecycle of Problem Management includes stages such as Detection and logging, where problems are identified and recorded; Investigation and diagnosis, which involves analyzing the identified problems to determine their causes; and Resolution and closure, where solutions are implemented, and the problem is officially closed.

Service Request Management, on the other hand, deals primarily with handling service requests from users, which may involve fulfilling requests for new services, changes, or information. While related to the overall IT Service Management framework, it operates under its own processes and objectives apart from Problem Management. Thus, the distinction between these two management areas is essential to understand their differing roles in delivering IT services effectively.
