Quality Hold Time at 7.2% retest and documentation allowance: a worked example

Suppose retest and documentation allowance falls to 7.2%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate hours product will remain on quality hold for dairy or frozen food testing, disposition, release review, or rework decision.

The inputs for this scenario

  • Lots or quality checks on hold: 120 lots or checks (held at the documented default)
  • QA release completion rate: 12 checks / hr (held at the documented default)
  • Retest and documentation allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base QA review time = lots or quality checks on hold รท QA release completion rate.
  • Required quality hold time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base QA review time works out to 10 hr at these inputs.
  • Retest and documentation allowance works out to 7.2 % at these inputs.
  • QA release completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where retest and documentation allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • It divides the number of lots or checks on hold by the QA release completion rate to get base review hours, then adds a retest and documentation allowance. 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.

Results at a glance

  • Required quality hold time: 10.72 hr (headline result)
  • Base QA review time: 10 hr
  • Retest and documentation allowance: 7.2 %
  • QA release completion rate: 12 pieces / min
