Incident management restores service; problem management investigates causes; change management governs modifications. Related records represent different goals.
Before you start
You should understand tables, records and the difference between client-side and server-side scripts. Work in a development instance with representative permissions. Identify execution scope, transaction timing and the current user before attributing behavior to a platform script or business rule.
The practical goal is to reason through this situation: Restore a failing service through an incident, investigate recurrence through a problem and govern the permanent fix as a change. Read the walkthrough first, then try the interview exercise before opening its answer. The important part is explaining the decision and its consequences, rather than remembering a definition alone.
Step-by-step walkthrough
Step 1: Restore the service
An incident tracks immediate disruption and restoration.
Step 2: Investigate recurring cause
A problem record owns deeper evidence and prevention work.
Step 3: Govern the corrective change
A change controls implementation risk and approval where required.
Worked scenario
Restore a failing service through an incident, investigate recurrence through a problem and govern the permanent fix as a change.
An outage is mitigated by restarting a component, restoring users while the underlying defect remains. Repeated occurrences justify a linked problem investigation. The permanent configuration fix proceeds through the applicable change process; closing the incident does not prove the cause has been removed.
Common mistake
Converting every incident into a problem adds overhead without establishing investigation value.
Verify the behavior
Trace restoration, investigation and implementation outcomes as distinct linked records.
Interview exercise
Describe a recurring outage workflow.
Answer and reasoning
Explain restoration first, evidence gathering second and controlled corrective change, retaining links between the records.
