The correct answers are B and D because CCPS emphasizes that audit findings must be based on sufficient, corroborated evidence , not isolated observations.
Option B is correct because the auditor should capture and document all relevant input , including operator concerns. However, a single statement is not enough to justify a formal finding. It should be treated as potential evidence requiring further evaluation .
Option D is also correct because auditors are expected to seek additional information and validate observations . Interviewing more operators, reviewing training records, and examining performance data helps determine whether the concern represents a systemic issue or an isolated opinion .
Option A is incorrect because immediately classifying a finding without verification contradicts the CCPS principle of evidence-based auditing . Option C is incorrect because operator interviews are a critical part of audits , providing insight into how systems function in practice.
CCPS highlights that effective audits rely on triangulation of evidence —combining interviews, documentation, and observations—to ensure findings are accurate, objective, and meaningful for continuous improvement.
