When conducting an investigation, what should the CAC ensure is documented?

The correct choice emphasizes the importance of comprehensive documentation in investigations. Proper documentation is crucial because it provides a complete record of all findings, methodologies, and evidence collected throughout the investigative process. This thorough approach ensures that every detail is captured, facilitating transparency and accountability.

By documenting all investigative findings, the CAC helps establish a clear narrative of the investigation, allowing for informed analysis and conclusions. This documentation can also be essential for potential legal proceedings, regulatory compliance, and future reference. In essence, thorough documentation supports the integrity of the investigative process and reinforces the credibility of the findings.

In contrast, focusing solely on testimonies from expert witnesses, a summary of public opinion, or just the evidence related to violations can lead to incomplete or biased perspectives, which may undermine the investigation's validity. Comprehensive documentation encompasses all elements of the investigation, making it vital for a thorough understanding and effective resolution of the issues at hand.
