What is the primary reason for thoroughly documenting mistakes made during an investigation?

• A. Forgotten
• B. Briefly discussed in the report
• C. Well documented in the report
• D. Verbally discussed and no documentation

Answer: (C)

Thoroughly documenting mistakes creates an accurate, verifiable trail of the investigation. This is essential because mistakes reveal where processes failed and what needs to change, and having them well documented in the report ensures accountability, supports root-cause analysis, and guides corrective actions and training. When mistakes are only forgotten, only briefly discussed, or handled verbally with no written record, details can be lost, misinterpreted, or never acted on, which prevents learning and improvement. Therefore, the best practice is to include a complete, clear record of what went wrong and why within the investigation report.
