Why is documenting an incident timeline important in investigations?

• A. It records only the date of the incident.
• B. It replaces the need for root cause analysis.
• C. It provides a chronological record from detection to resolution to help identify root causes and verify corrective actions.
• D. It is optional and not used in most investigations.

Answer: (C)

Documenting an incident timeline is essential because it provides a clear, chronological record of everything from when the issue was detected to when it was resolved. This sequence helps investigators see how events unfolded, link actions and decisions to outcomes, and identify exactly where things went wrong or overlapped, which is key for uncovering root causes. The timeline also shows what was done, by whom, and when, making it possible to verify that corrective actions were implemented and are effective. In short, the timeline acts as a roadmap for understanding the incident, communicating to all stakeholders, and preventing recurrence. It’s not just about recording dates, it doesn’t replace the root cause analysis, and it isn’t optional—the timeline supports both accurate investigation and accountability.
