When two people give conflicting accounts of the same event, you have to determine what likely happened and explain how you got there. Credibility assessment is where investigations most often become vulnerable. Reasoning goes undocumented. Findings rest on impression rather than evidence. The analysis does not hold when it is challenged.
This three hour recorded course sets out a structured approach to assessing credibility and reliability in workplace investigations. Michelle Bird works through how to evaluate witness evidence, weigh competing accounts, and document your reasoning so that findings are clear, objective, and defensible.
The course is self-paced. Complete it in one sitting or in sections, and return to it as often as your caseload requires.
