Application
Audit risk model is used by the auditors to manage the overall risk of an audit engagement.
Auditors proceed by examining the inherent and control risks pertaining to an audit engagement while gaining an understanding of the entity and its environment.
Detection risk forms the residual risk after taking into consideration the inherent and control risks pertaining to the audit engagement and the overall audit risk that the auditor is willing to accept.
Where the auditor's assessment of inherent and control risk is high, the detection risk is set at a lower level to keep the audit risk at an acceptable level. Lower detection risk may be achieved by increasing the sample size for audit testing. Conversely, where the auditor believes the inherent and control risks of an engagement to be low, detection risk is allowed to be set at a relatively higher level.
