Root cause analysis in SAD maintenance focuses on tracing an incident to its origin and naming the actions needed to prevent recurrence. The most complete RCA includes a timeline of events, contributing factors, the identified root cause, the impact of the incident, corrective actions to fix the root cause, preventive actions to stop similar issues in the future, and a verification step to confirm that the actions worked. This set of elements ensures you not only remediate the immediate problem but also provide evidence that the fix is effective and that the issue won’t recur.

Other options describe different processes. Change management centers on evaluating and approving changes, including risk assessment, rollback planning, and verification. A post-incident recap focuses on conclusions and owner assignments. A disaster recovery plan outlines backup locations and restart procedures. RCA stays squarely about diagnosing the underlying cause and documenting actions to prevent repetition, even though its results may feed into change management or recovery planning activities.
