Estimate first article inspection time for quality & metrology using production inputs, allowances, and safe planning assumptions. Type your workload and rate to see how many minutes the run actually takes.

What this calculator does

  • Estimate first article inspection time for quality & metrology using production inputs, allowances, and safe planning assumptions.
  • Use it when first article inspection time in quality and metrology is changing rate or allowance and you want to see the impact.
  • Turns first article inspection time workload, first article inspection time completion rate, setup, handling, and delay allowance into a adjusted run time for first article inspection time in quality and metrology.

Formula used

  • Base first article inspection time = first article inspection time workload ÷ first article inspection time completion rate
  • Required first article inspection time = base first article inspection time × allowance factor

Inputs explained

  • First article inspection time workload: Enter the required workload from the work order, build plan, test queue, or maintenance job plan.
  • First article inspection time completion rate: Use a measured completion rate from a recent production report, time study, test log, or line observation.
  • Setup, handling, and delay allowance: Add the normal allowance for setup, checks, staging, breaks, minor stops, or retest time.

How to use the result

  • Reach for it when a customer asks for a lead time and you need a number you can defend in 30 seconds.
  • Setup, changeover, and major stoppages are not in the formula. Add them on top for quality and metrology jobs that include them.

Common questions

  • Why use this first article inspection time tool for quality and metrology? Estimate first article inspection time for quality & metrology using production inputs, allowances, and safe planning assumptions. You get a adjusted run time you can defend before quoting, scheduling, or sign-off.
  • Which assumptions drive the adjusted run time? first article inspection time workload, first article inspection time completion rate, setup, handling, and delay allowance usually move the adjusted run time most. Pull from measured quality and metrology runs, supplier data, and recent quotes rather than memory.
  • How should I act on the output? Treat the run time as a planning estimate. Compare two scenarios before you commit hours on the schedule for quality and metrology.
  • What should I double-check before acting? Confirm the rate against a recent shift report, not the spec sheet, and account for changeover and setup that the calculator does not.
