System-based auditing was, at one time, the
universally accepted method of carrying out audit work, but auditors are
increasingly adopting a business risk-based approach. We will look at this in
the next chapter.

It is important for student to relate the audit
tests described to the internal controls and the Assertions so that a proper
understanding of systems-based auditing can be obtained.

Students will, however, also need to refer to later
chapters where we look specifically at testing balance sheet items because,
whether the audit approaches are systems-or risk-based, the balance sheet still
needs to be verified by substantive testing at some level.
