QA Release Time at 1.44% qa sampling rate: a worked example in food & beverage manufacturing

Suppose qa sampling rate falls to 1.44%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate QA release sample workload from lot population, sample rate, and minimum sample size.

The inputs for this scenario

  • Lots, cases, or units in release scope: 2,400 units (held at the documented default)
  • QA sampling rate: 1.44 % (the input this scenario stresses; the baseline uses 2)
  • Minimum required release samples: 12 samples (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Calculated qa release time sample = lots, cases, or units in release scope × qa sampling rate.
  • Required sample size works out to 35 samples at these inputs, and this is the headline figure for the scenario.
  • Calculated sample works out to 35 samples at these inputs.
  • Minimum sample size works out to 12 samples at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where qa sampling rate sits at 2% and the headline result is 48 samples, this scenario comes in 27.08% below the baseline at 35 samples.
  • Computes the QA release sample size as the population times the sampling rate, then enforces a minimum floor by taking the larger of the two. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
