Quality & Metrology calculator
Inspection Time Calculator
Estimate inspection time for quality & metrology using production inputs, allowances, and safe planning assumptions. Adjust the allowance to model setup, breaks, and minor stops without redoing the math.
What this calculator does
- Estimate inspection time for quality & metrology using production inputs, allowances, and safe planning assumptions.
- Use it when inspection time in quality and metrology is being added to next week's schedule and you need an honest hours estimate.
- Turns inspection time workload, inspection time completion rate, setup, handling, and delay allowance into a adjusted run time for inspection time in quality and metrology.
Formula used
- Base inspection time = inspection time workload ÷ inspection time completion rate
- Required inspection time = base inspection time × allowance factor
Inputs explained
- Inspection time workload: Enter the required workload from the work order, build plan, test queue, or maintenance job plan.
- 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 inspection time tool for quality and metrology? Estimate 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? inspection time workload, 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.
- What do I do with this number? Use it to quote lead time for quality and metrology jobs and to push back on requests that do not fit the floor.
- What should I verify first? Cross-check against last week's run for a similar part before you trust it for a quote.
