Audit Program

Overview

An Audit Program is a documented set of audit objectives, scope, procedures, evidence requirements, responsibilities, timing, sampling approaches, and reporting steps for an engagement or recurring audit area. The control exists to obtain and document sufficient, appropriate evidence to evaluate activities or controls against defined criteria with an appropriate level of independence. It is the execution plan for audit work, not the organization’s complete compliance management system or the final audit opinion. It should be interpreted alongside Audit Sampling because the concepts can affect the same decision without representing the same control, event, or risk.

The workflow establishes objectives, scope, criteria, populations, risks, procedures, selection methods, responsibilities, and review requirements before testing. Auditors evaluate both design and operation, investigate exceptions, consider limitations, and avoid extending conclusions beyond the evidence and period examined. In this context, the program should map procedures to risks and criteria, identify population sources, specify testing depth, record deviations, require supervisory review, and preserve enough evidence for an independent reviewer to reproduce conclusions.

It should connect the term to External Audit where that relationship changes access, transaction treatment, investigation, communication, or recovery.

Workpapers should identify the source population, samples, procedures, evidence, preparer and reviewer, deviations, management explanations, judgments, findings, and connection between evidence and conclusion. Independence, access restrictions, retention, and changes after the test date should be documented.

Useful measures include plan completion, coverage of high-risk areas, exception rate, repeat findings, overdue remediation, evidence quality, review adjustments, scope limitations, and time from fieldwork to final report.

The relationship with Control Testing should be documented where it affects residual risk or control ownership.
