Evidence Depth vs Audit Speed
Business ContextAuditors need sufficient evidence to support defensible conclusions, but deeper examination requires additional testing, corroboration, analysis, and review. When every subject receives maximum evidence depth, engagements can become too slow to provide timely assurance.
Audit TRIZ ResolutionEvidence depth should vary according to risk, uncertainty, and the strength of existing evidence. High-risk or contradictory conditions receive deeper corroboration, while reliable evidence streams and lower-risk areas require fewer procedures. Depth is concentrated where additional evidence materially changes assurance confidence.
Applicable TRIZ Principles
Principle 3 – Local Quality applies different evidence depth according to the risk and uncertainty of each audit area.
Principle 5 – Merging uses evidence capable of supporting multiple related audit objectives.
Principle 10 – Prior Action obtains and validates critical evidence before intensive fieldwork begins.
Expected Outcome
Faster evidence collection
Preserved conclusion reliability
Better risk-focused testing
Shorter engagement cycles
Decision Indicators
Fieldwork expands because auditors continue collecting evidence after conclusions are already well supported.
High- and low-risk areas receive similar testing depth.
Evidence collection regularly delays reporting.
Auditors perform additional procedures without changing conclusions.
Engagement speed improves only when evidence requirements are reduced indiscriminately.
