Audit plan is work plan that reflects the design and performance of all audit procedures, consisting of a detailed approach for the nature, timing and extent of audit procedures to be performed (including the performance of risk assessment procedures) and the rationale
for their selection.
The audit plan begins by planning risk assessment procedures and once
these procedures have been performed it is updated and changed to reflect the further audit procedures needed to respond to the results of the risk assessments. Also called audit program.
