The llA Standards require each engagement to be appropriately staffed with

adequately skilled resources, which may lead a CAE to consider hiring external

experts for some projects. At the same time, internal auditors are expected to be

able to apply a systematic, disciplined approach to conducting an engagement, and

quickly understand the presence or lack of controls within business processes. So,

where should a CAE draw the line? Create a 2x2 table that lists some of the

opportunities and risks of letting an audit team review a new area versus engaging

expert help.
