Gauge R&R Workload at 7.2% setup and msa analysis allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop setup and msa analysis allowance to 7.2%, then walk the calculation through step by step. Estimate the time required to run a gauge R&R study from the planned measurement count, observed measurement rate, and added setup or analysis allowance.

The inputs for this scenario

  • Gauge R&R measurements required: 120 readings (held at the documented default)
  • Measurement completion rate: 12 readings / min (held at the documented default)
  • Setup and MSA analysis allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base measurement time = gauge R&R measurements required รท measurement completion rate.
  • Total gauge R&R study time works out to 10.72 min at these inputs, and this is the headline figure for the scenario.
  • Base measurement time works out to 10 min at these inputs.
  • Setup and analysis allowance works out to 7.2 % at these inputs.
  • Measurement completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where setup and msa analysis allowance sits at 10% and the headline result is 11 min, this scenario comes in 2.55% below the baseline at 10.72 min.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to setup and msa analysis allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It treats measurement rate as constant, but real readings slow down for awkward fixturing, large parts, or destructive setups, and it does not capture wait time between operators in a crossed study.

Results at a glance

  • Total gauge R&R study time: 10.72 min (headline result)
  • Base measurement time: 10 min
  • Setup and analysis allowance: 7.2 %
  • Measurement completion rate: 12 pieces / min
