Step-by-Step Detailed Explanation:
A . Review a random sample of concluded disciplinary reports to assess how the policy was applied in each case:
This is the correct answer because reviewing documented reports provides objective evidence of whether decisions complied with policies. This approach ensures that the auditor relies on concrete evidence rather than subjective opinions or observations.
B . Interview a sample of impacted employees for their opinions on the clarity and fairness of the policy:
While employee feedback is valuable, it is subjective and does not provide sufficient evidence of compliance with the documented policy.
C . Observe several disciplinary hearings to determine whether they are in compliance with the policy:
Observations are limited to current proceedings and do not account for how policies were applied in past cases, making this approach less comprehensive.
D . Conduct an interview to assess the disciplinary hearing chairman's understanding of the policy and its appropriate use:
Interviews provide insight into understanding and intent but do not offer evidence of actual compliance.
