Commentary
05 For an internal information systems audit function, an
audit charter should be prepared for ongoing activities.
The audit charter should be subject to an annual review
or more often if the responsibilities are varied or
changed. An engagement letter may be used by the
internal IS auditor to further clarify or confirm
involvement in specific audit or non-audit assignments.
For an external IS audit, an engagement letter should be
normally prepared for each audit or non-audit
assignment.
