Supplier Lot Acceptance Rate at 99% contractual supplier acceptance target: a worked example

What does the result look like when contractual supplier acceptance target reaches 99%? The full calculation is worked below with real intermediate numbers. a supplier quality manager needs to compare accepted incoming lots against the supplier performance target

The inputs for this scenario

  • Supplier lots accepted at receiving inspection: 86 lots (unchanged)
  • Supplier lots received for inspection: 94 lots (unchanged)
  • Contractual supplier acceptance target: 99 % (raised for this scenario; the documented default is 98)

Working through the calculation

  • Applying the documented formula (Supplier lot acceptance rate = accepted supplier lots ÷ supplier lots received × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 91.49 % lot acceptance for supplier lot acceptance rate, the number this scenario is built around.
  • At this operating point the engine returns 7.51 percentage points for acceptance gap to target.
  • At this operating point the engine returns 86 lots for supplier lots accepted.
  • At this operating point the engine returns 94 lots for supplier lots received.

How this compares with the baseline

  • Against the tool's baseline example, where contractual supplier acceptance target sits at 98% and the headline result is 91.49 % lot acceptance, this scenario lands almost exactly on the baseline at 91.49 % lot acceptance.
  • A figure at this level is achievable when contractual supplier acceptance target is genuinely sustained, not just peaked for a shift. Lot count alone ignores lot size and defect severity — one rejected 5,000-piece lot of flight-critical fasteners is not equivalent to one rejected 12-piece lot of brackets.

  • Supplier lot acceptance rate: 91.49 % lot acceptance (headline result)
  • Acceptance gap to target: 7.51 percentage points
  • Supplier lots accepted: 86 lots
  • Supplier lots received: 94 lots
