Flavors, Fragrances & Aroma Chemicals worked example

QA Release Time at 23% retest, documentation, and hold allowance: a worked example in flavors, fragrances & aroma chemicals

Push retest, documentation, and hold allowance up to 23% and the picture changes. This example computes every intermediate figure at that operating point. Use it when scheduling GC, density, refractive index, color, odor evaluation, allergen documentation, COA review, and batch record approval.

The inputs for this scenario

  • Lots awaiting QA release: 42 lots (unchanged)
  • QA lots released per hour: 5.5 lots / hr (unchanged)
  • Retest, documentation, and hold allowance: 23 % (raised for this scenario; the documented default is 20)

Working through the calculation

  • Applying the documented formula (Base qa release time = lots awaiting qa release รท qa releases completed per hour) to the inputs above produces each figure below.
  • At this operating point the engine returns 9.39 hr for required qa release time, the number this scenario is built around.
  • At this operating point the engine returns 7.64 hr for base qa release time.
  • At this operating point the engine returns 23 % for retest, documentation, and hold allowance.
  • At this operating point the engine returns 5.5 lots / hr for qa releases completed per hour.

How this compares with the baseline

  • Against the tool's baseline example, where retest, documentation, and hold allowance sits at 20% and the headline result is 9.16 hr, this scenario comes in 2.5% above the baseline at 9.39 hr.
  • It converts a backlog of lots and a release rate into the labor-hours needed to clear the queue, then inflates that by a retest and documentation allowance. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Required qa release time: 9.39 hr (headline result)
  • Base qa release time: 7.64 hr
  • Retest, documentation, and hold allowance: 23 %
  • QA releases completed per hour: 5.5 lots / hr
