What is evidence friction?
Evidence friction is the effort an audit team spends obtaining sufficient, appropriate evidence — and establishing that it can be relied on. The chase rounds. The wrong and partial deliveries. The log that silently covers half the observation window. The noise that buries the one record that was asked for. The hours spent deciding whether a report an automation platform produced can be trusted at all.

Why it is more than an annoyance
An auditor concludes on the evidence received. Friction at intake therefore sits directly upstream of the conclusion: a set that arrives wrong, short, or unverifiable is not just slow — it is the raw material of a weak opinion, and every round of the chase is unbilled time on a fixed fee.
The falsifiable claim
The research hypothesis, stated so it can fail: evidence friction is a leading indicator of engagement risk and of realization bleed. Where friction concentrates, inspection findings and fee erosion follow. This is a hypothesis under active study — not an assumption — by the AuditEx Program, which measures the friction of audit and GRC work while never grading the quality of anyone's work.
Friction beyond intake
Evidence friction is the founding family, not the whole taxonomy. The work also binds at the interface between IT audit and financial-reporting audit, where one team's testing must be translated into another team's conclusions, and in the effort of making finished work fit the documentation conventions review and inspection expect.
- Evidence friction = the effort of obtaining evidence and establishing reliance on it.
- Auditors conclude on the evidence received — intake friction sits upstream of the opinion.
- Hypothesis under study: a leading indicator of engagement risk and realization bleed.
- Measured by the AuditEx Program — experience and friction, never audit quality.
FAQ
- What is evidence friction?
- The effort an audit team spends obtaining sufficient, appropriate evidence — and establishing that it can be relied on: re-request rounds, wrong and partial deliveries, files that silently cover only part of the observation window, irrelevant volume that buries the record you asked for, and the growing work of verifying evidence produced by compliance-automation platforms.
- Is evidence friction just inefficiency?
- No — that is the hypothesis under study. Because an auditor concludes on the evidence received, friction at intake sits directly upstream of the conclusion. The research claim, stated falsifiably: evidence friction is a leading indicator of engagement risk and of realization bleed on fixed-fee work. It is being tested, not assumed.
- Who studies evidence friction?
- The AuditEx Program — the field’s first instrument-grade study of the friction of audit and GRC work. It measures experience and friction, never the quality of anyone’s work, and no client evidence ever enters the research.
