The purpose of a planning memorandum for an audit engagement, according to IIA guidance, is to document preliminary information that will be useful to the audit team. This includes background information on the area being audited, key risks identified, the scope of the audit, and any initial observations that might impact the audit's focus. The planning memorandum serves as a foundational document that guides the audit team's efforts and ensures that everyone involved in the engagement has a clear understanding of the audit's objectives and context.
IIA Reference:
IIA Standard 2200: Engagement Planning and IIA Standard 2201: Planning Considerations require the preparation of documents that summarize the preliminary planning steps, which are critical to ensuring that the audit is well-focused and aligned with the organization's risks and objectives. The planning memorandum is a key output of this process.
