Gauge Repeatability Score with repeatability impact score of 20 score: a worked example

This scenario runs the gauge repeatability score calculation on the strong side: repeatability impact score of 20 score, with every other input held at its documented default. Use it before commissioning a new gauge, reacting to gauge R&R concerns, or deciding which inspection fixtures need containment or redesign.

The inputs for this scenario

  • Repeatability impact (severity) score: 20 score (raised for this scenario; the documented default is 8)
  • Repeatability error occurrence score: 5 score (unchanged)
  • Detection-control weakness score: 4 score (unchanged)

Working through the calculation

  • Applying the documented formula (Gauge Repeatability Score score = repeatability impact score × repeatability occurrence score × detection-control weakness score) to the inputs above produces each figure below.
  • At this operating point the engine returns 10.75 score for gauge repeatability score score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for repeatability impact score.
  • At this operating point the engine returns 5 score for repeatability occurrence score.
  • At this operating point the engine returns 4 score for detection-control weakness score.

How this compares with the baseline

  • Against the tool's baseline example, where repeatability impact score sits at 8 score and the headline result is 5.95 score, this scenario comes in 80.67% above the baseline at 10.75 score.
  • Use it during MSA planning, PPAP gauge sign-off, or any time you must rank which gauges and fixtures get studied or recalibrated first. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Gauge Repeatability Score score: 10.75 score (headline result)
