How do you calculate a calibration audit readiness score?

Multiply each factor by its weight and sum: severity x 0.40 + occurrence x 0.35 + detection x 0.25. With severity 6, occurrence 4, and detection 3, the score is 2.4 + 1.4 + 0.75 = 4.55.

What do severity, occurrence, and detection mean here?

Severity is how damaging a finding would be (a major nonconformity versus a minor note), occurrence is how likely the gap is to be present, and detection is how likely you would catch it before the auditor does. Higher detection scores mean worse detectability.

Why is severity weighted highest?

In an audit, the consequence of a finding drives the risk more than how often it occurs. Weighting severity at 40% pushes high-impact gaps, like missing traceability, to the top of the priority list even if they are rare.

What is a good audit readiness score?

Lower is better since it means less exposure. There is no universal threshold; the value is in ranking. A 4.55 only matters relative to your other scored items, so close the highest scorers first.

How is this different from a standard FMEA RPN?

A classic FMEA multiplies severity x occurrence x detection into an RPN. This model uses a weighted sum with fixed weights instead, which keeps scores on a stable, comparable scale and avoids RPN's known issue of identical numbers from very different inputs.

How do I lower an audit readiness risk score?

Attack the highest-weighted factor first: reduce severity by adding controls that contain a finding's impact, reduce occurrence by fixing the root cause, and reduce detection score by adding internal audits that catch gaps before the external auditor.

Calibration Lab & Gauge Management calculator

Calibration Audit Readiness Calculator

Calibration audit readiness is a weighted risk score that ranks how exposed your calibration program is to findings in an ISO 9001, IATF 16949, or ISO/IEC 17025 audit. It borrows the FMEA logic of severity, occurrence, and detection but tunes the weights for audit context, where the impact of a finding (severity) matters most. Quality managers and metrology leads use it to triage which gaps to close before an auditor arrives, instead of treating every nonconformity as equally urgent. Scoring each risk on the same scale makes a stack of audit concerns directly comparable so limited prep time goes to the highest-risk items.

What this calculator does

Score calibration audit readiness risk by ranking certificate gaps, overdue assets, traceability issues, and record-control weaknesses before an ISO 17025, IATF, customer, or internal audit.
Use it when calibration audit readiness in calibration lab and gauge management needs a defensible ranking against other calibration lab and gauge management risks for the next review.
It computes a single weighted risk score from severity (40%), occurrence (35%), and detection (25%) to rank calibration audit exposures.

Formula used

Calibration audit readiness risk score = severity score × 0.40 + occurrence score × 0.35 + detection score × 0.25
Use the same scoring scale for every risk being ranked so the weighted score is comparable.

Inputs explained

Audit finding severity score:
Audit issue occurrence score:
Pre-audit detection score:

How to use the result

Use it when prepping for a calibration system audit and you need to prioritize which gaps to close first.
The score only ranks risks relative to each other; it has meaning only when every item uses the same scoring scale and the weights match your audit's true emphasis.
