Which of the following methods can an audit program manager use to establish consistency among auditors?

Developing performance appraisals is a direct management method for establishing consistency. An audit program manager can create standardized performance criteria for all auditors, focusing on adherence to established audit procedures, methodologies, and reporting formats. This formal evaluation process provides a structured mechanism to measure and enforce consistent performance, identify deviations, and implement corrective actions. By aligning individual performance goals with the audit program's objective of consistency, appraisals ensure that all auditors are held to the same standard, leading to more reliable and comparable audit outcomes. This is a key responsibility in managing auditor competence and performance as outlined in international auditing guidelines.

B. Assigning auditors to permanent audit teams can create inconsistency between teams, as each team may develop its own unique sub-culture and methods.
C. Requiring auditors to read audit journals and references improves competence but does not ensure the consistent application of that knowledge in practice.
D. Requiring auditors to develop their own procedures manual would actively create inconsistency by promoting multiple, non-standardized approaches to auditing.

1. ISO 19011:2018, Guidelines for auditing management systems. Clause 7.6, "Maintaining and improving auditor competence," states that the audit programme manager should establish a process for the continual evaluation of auditors' performance. This evaluation, often formalized through appraisals, is used to ensure auditors consistently meet the program's requirements.

2. Russell, J.P. (Ed.). (2021). The ASQ Certified Quality Auditor Handbook (5th ed.). ASQ Quality Press. In Chapter 4, "Audit Program Management," the section on "Auditor Performance Monitoring" (p. 57) explicitly lists "performance appraisals" as a method for monitoring auditor performance to ensure they are meeting the objectives of the audit program, which includes consistency.

3. Sower, V. E. (2010). Auditing for process improvement. ASQ Quality Press. Chapter 3, "The Audit Program," discusses the audit manager's role in ensuring the effectiveness of the program, which includes evaluating auditor performance to ensure consistent and objective audits are conducted according to established procedures. Performance evaluation is presented as a key control mechanism.
