Audit Risk Model
Audit Risk Model by Area
Inherent, control and detection risk assessments per audit area driving planned audit effort.
Why the audit risk model by area matters
The audit risk model, where audit risk is a function of inherent, control and detection risk, governs how internal and external auditors plan effort under the ISSAIs and ISAs. Assessing each component per audit area is what justifies allocating more procedures to high-risk areas and fewer to low-risk ones, keeping the audit both effective and efficient. AuditPro Core records inherent, control and detection assessments by area so planned audit effort is demonstrably risk-driven rather than habitual.

The audit risk model
Audit risk is the risk of an inappropriate opinion, decomposed into inherent, control and detection risk. Auditors set detection risk to achieve an acceptably low overall audit risk given the other two.
Inherent and control risk
Inherent and control risk together form the risk of material misstatement, which the auditor assesses but cannot change. They are properties of the institution, not of the audit.
Detection risk as the lever
Detection risk is the only component the auditor controls, by varying the nature, timing and extent of procedures. Higher assessed misstatement risk forces lower acceptable detection risk and more work.
Effort allocation
Mapping the model across audit areas turns risk assessment into a defensible plan. Areas with high combined risk attract more procedures; low-risk areas justify a lighter touch.
How AuditPro Core Bridges the Gap
- Per-area assessment: inherent, control and detection risk are captured for each audit area on a consistent scale.
- Effort linkage: assessed risk maps to planned procedures so the audit plan is visibly risk-driven.
- Traceability to rationale: each assessment records the basis for the rating, supporting review and challenge.
- Audit-ready planning evidence: the model exports to document risk-based planning for quality review and AGSA scrutiny.
Key Takeaways
- Audit risk decomposes into inherent, control and detection risk.
- Inherent and control risk are assessed, not chosen, by the auditor.
- Detection risk is the lever that drives the extent of procedures.
- Per-area assessment makes effort allocation defensible and efficient.
