Rework Cost at 110% rework scope captured: a worked example in flavors, fragrances & aroma chemicals

This scenario runs the rework cost calculation on the strong side: 110% rework scope captured, with every other input held at its documented default. Use it when a batch needs odor adjustment, color correction, dilution, filtration, remixing, relabeling, repackaging, retesting, or customer disposition.

The inputs for this scenario

  • Lots or batches requiring rework: 9 lots (unchanged)
  • Rework cost per lot: 1,250 $ / lot (unchanged)
  • Rework scope captured: 110 % (raised for this scenario; the documented default is 100)
  • Fixed retest, documentation, or disposal cost: 1,800 $ (unchanged)

Working through the calculation

  • Applying the documented formula (Variable rework cost = lots or batches requiring rework × rework cost per lot × rework scope captured) to the inputs above produces each figure below.
  • At this operating point the engine returns 14,175 $ for total rework cost, the number this scenario is built around.
  • At this operating point the engine returns 1,575 $ / piece for rework cost per affected lot.
  • At this operating point the engine returns 12,375 $ for variable rework cost.
  • At this operating point the engine returns 1,800 $ for fixed retest, documentation, or disposal cost.

How this compares with the baseline

  • Against the tool's baseline example, where rework scope captured sits at 100% and the headline result is 13,050 $, this scenario comes in 8.62% above the baseline at 14,175 $.
  • Use it when lots fail organoleptic or analytical release and you must price repair-versus-scrap, or when building a monthly cost-of-poor-quality report for a blending or distillation line. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Total rework cost: 14,175 $ (headline result)
  • Rework cost per affected lot: 1,575 $ / piece
  • Variable rework cost: 12,375 $
  • Fixed retest, documentation, or disposal cost: 1,800 $
