How is the calibration compliance score calculated?

Multiply severity by 0.40, occurrence by 0.35, and detection by 0.25, then add them. With severity 6, occurrence 4, and detection 3, the weighted score is 2.4 + 1.4 + 0.75 = 4.55.

Why is severity weighted more heavily?

At 40%, severity dominates because a high-consequence compliance failure — shipping nonconforming product from an out-of-cal gauge — matters more than one that is merely frequent or hard to detect. The weighting forces the worst outcomes to the top.

What is a high compliance score?

On a 1-10 input scale the weighted score also runs 1-10. Anything in the upper third (roughly 7+) warrants immediate action; a 4.55 sits mid-range, meaning monitor and improve but not an emergency.

How does this differ from a standard RPN?

A classic FMEA multiplies severity, occurrence, and detection, which can let a single high number dominate erratically. This weighted-sum approach gives smoother, more comparable rankings and explicitly prioritizes severity.

What scoring scale should I use for the inputs?

Use one consistent scale — typically 1-10 — for every risk you compare, and define what each level means for severity, occurrence, and detection so different raters score the same way.

How do I lower a compliance score?

You usually cannot change severity, so attack occurrence (more reliable calibration scheduling) and detection (better in-process gauge checks). Improving detection from 3 toward 1 directly pulls the weighted score down.

Calibration Lab & Gauge Management calculator

Calibration Compliance Score Calculator

The calibration compliance score is a weighted risk number that ranks calibration-related failure modes the way an FMEA does, but tuned for the metrology lab. It blends how bad a compliance failure would be (severity), how often it is likely to occur, and how well your controls would catch it before product ships (detection). Quality engineers and lab managers use it to decide which gauges, processes, or audit gaps to fix first when resources are limited. Because severity carries the most weight, the score correctly pushes high-consequence compliance risks — like an uncalibrated gauge releasing nonconforming parts — to the top of the list.

What this calculator does

Score the compliance risk of a calibration issue by weighting severity, occurrence, and detection so quality or audit teams can rank findings consistently.
Use it when calibration compliance 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%) so calibration risks can be ranked consistently.

Formula used

Calibration compliance 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

Compliance impact severity score:
Compliance occurrence score:
Control detection score:

How to use the result

Use it when prioritizing corrective actions, building a calibration FMEA, or deciding where to focus limited audit and verification effort.
The score is only meaningful if every risk is rated on the same scoring scale; mixing 1-5 and 1-10 scales across items makes comparisons invalid.
