Combined Assurance
Assurance Provider Reliance
Extent to which internal audit relies on other providers, with reliance volume and quality scores.
Why assurance provider reliance matters
Under the ISSAIs and combined assurance principles, internal audit can avoid duplicating work by relying on other providers, but only where their work is sufficiently competent, objective and high quality. Tracking the extent of reliance, with volume and quality scores, ensures that efficiency gains do not come at the cost of assurance integrity. AuditPro Core records reliance placed on each provider with its quality assessment so internal audit can evidence that its reliance decisions are justified, not merely convenient.

Reliance on others
Reliance means using another provider's work instead of performing the same procedures directly. It conserves scarce audit resource but transfers dependence onto the reliability of that other work.
Competence and objectivity
Before relying on a provider, internal audit must assess its competence and objectivity. Reliance on work that is weak or conflicted imports those weaknesses into the audit's conclusions.
Quality scoring
Rating the quality of each provider's work makes the reliance decision evidence-based. A high reliance volume paired with a low quality score is a warning that the audit is leaning on a weak foundation.
Reliance versus duplication
Appropriate reliance reduces wasteful duplication, but excessive reliance on inadequate work creates a false sense of coverage. The balance must be deliberate and documented.
How AuditPro Core Bridges the Gap
- Reliance tracking: the volume of work relied upon is recorded per provider alongside its quality rating.
- Quality flags: high reliance on low-quality work is surfaced as a risk to assurance integrity.
- Decision traceability: each reliance decision links to the competence and objectivity assessment behind it.
- Audit-ready reliance log: the record exports to evidence justified reliance for quality review and AGSA.
Key Takeaways
- Reliance conserves resource but transfers dependence onto others' work.
- Assess competence and objectivity before relying on any provider.
- High reliance with low quality is a warning, not an efficiency.
- Document reliance decisions to keep them defensible under review.
