According to IIA guidance, which of the following statements about working papers is false?

According to IIA guidance, the primary purpose of working papers is to document the audit work performed, the evidence gathered, and the basis for the auditor's conclusions and recommendations. While they provide the necessary support and rationale for the recommendations presented in the final audit report, their function does not extend to directly assisting management in the implementation of those recommendations. The implementation phase is a management responsibility, guided by the final audit communication, not the detailed working papers.

B. They provide support for communication to third parties. This is a valid function. Working papers serve as the primary evidence supporting audit results, which may be reviewed by or communicated to external auditors, regulators, or other third parties.
C. They demonstrate compliance with auditing standards. This is a core purpose. Working papers are the principal record demonstrating that the internal audit activity has conformed with the IIA's International Standards for the Professional Practice of Internal Auditing.
D. They contribute to development of the internal audit staff. This is a recognized benefit. The review of working papers by supervisors is a key tool for providing feedback, coaching, and on-the-job training, thereby aiding in staff development.

The standard states, "Internal auditors must document relevant information to support the conclusions and engagement results." The focus is on support for conclusions, not implementation assistance.

2. The Institute of Internal Auditors (IIA). (2017). Implementation Guide 2330: Documenting Information. This guide lists the primary purposes of engagement working papers, which include: "Demonstrating the internal audit activity’s conformance with the International Standards for the Professional Practice of Internal Auditing," and "Aiding in the professional development of the internal audit staff." It does not list assisting in the implementation of recommendations as a purpose.

The Institute of Internal Auditors Research Foundation. Chapter 13, "Performing the Engagement and Communicating Results," details that working papers serve to document evidence, support conclusions, facilitate review, and demonstrate compliance with standards. The role described is one of substantiation, not implementation support.
