In which phase of Problem Management are known errors created and managed?
Error control is the specific phase of problem management where a problem, once its root cause has been identified and confirmed, is formally documented as a "known error." This phase involves creating and maintaining known error records, which detail the root cause, symptoms, and any available workarounds. Additionally, error control is responsible for initiating change requests to implement permanent solutions for these known errors, thereby preventing future incidents.
Why this answer
Known errors are created and managed during the Error Control phase of Problem Management. This phase focuses on documenting known errors in the Known Error Database (KEDB) after root cause analysis is complete, and managing them through their lifecycle until a permanent resolution (e.g., a change via RFC) is implemented. Error Control ensures that workarounds are available and that the known error is tracked for future resolution.
Exam trap
The trap here is that candidates confuse Problem Control (root cause analysis) with Error Control, mistakenly thinking known errors are created during root cause analysis rather than after it, when the cause is known and documented as a known error.
How to eliminate wrong answers
Option A is wrong because Incident Management handles restoring normal service operation as quickly as possible, not the creation or management of known errors. Option B is wrong because Problem Control (root cause analysis) identifies the underlying cause of problems but does not create or manage known errors; that occurs in the subsequent Error Control phase. Option D is wrong because Problem Identification is the initial phase where problems are detected and logged, not where known errors are created or managed.
