NPI, DFM/DFA & Engineering Change calculator
Pilot Yield Calculator
Estimate pilot yield for npi, dfm/dfa and engineering change using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed. Two counts and a target give you a rate plus how far you are from where you need to be.
What this calculator does
- Estimate pilot yield for npi, dfm/dfa and engineering change using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.
- Use it when pilot yield in npi, dfm/dfa and engineering change needs a clean rate and gap-to-target you can put on a tier board.
- Turns pilot yield count, total pilot yield population, target pilot yield rate into a rate for pilot yield in npi, dfm/dfa and engineering change.
Formula used
- Pilot yield rate = pilot yield count ÷ total pilot yield population × 100
- Pilot yield gap to target = pilot yield rate - target pilot yield rate
Inputs explained
- Pilot yield count: Enter the number of defects, passes, claims, shortages, conforming units, or events being measured.
- Total pilot yield population: Use the matching inspected, produced, tested, shipped, sampled, or installed population for the same period.
- Target pilot yield rate: Enter the KPI, specification, contract target, quality target, or internal control limit.
How to use the result
- Use it when pilot yield in npi, dfm/dfa and engineering change is being reviewed against a KPI.
- Trend matters more than a single snapshot; pull the result for the last several periods before you act.
Common questions
- What does the pilot yield calculator give me? Estimate pilot yield for npi, dfm/dfa and engineering change using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed. You get a rate you can defend before quoting, scheduling, or sign-off.
- Which assumptions drive the rate? pilot yield count, total pilot yield population, target pilot yield rate usually move the rate most. Pull from measured npi, dfm/dfa and engineering change runs, supplier data, and recent quotes rather than memory.
- What do I do with this number? Use the gap to target to prioritize the next npi, dfm/dfa and engineering change kaizen or corrective action.
- What should I double-check before acting? Confirm the counts came from the same time window and the same scope; mismatched scope is the most common error.
