Launch Sample Workload at 35% revision and rework allowance: a worked example

What does the result look like when revision and rework allowance reaches 35%? The full calculation is worked below with real intermediate numbers. Use this when planning sample room capacity for next season, estimating how many sample makers are needed, scheduling sample delivery dates for buyer approval, or deciding whether to outsource sample development.

The inputs for this scenario

  • Total launch samples required: 120 samples (unchanged)
  • Sample completion rate: 0.25 samples / hr (unchanged)
  • Revision and rework allowance: 35 % (raised for this scenario; the documented default is 30)

Working through the calculation

  • Applying the documented formula (Base sample workload = total samples required / sample completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 648 hr for required sample hours (with revisions), the number this scenario is built around.
  • At this operating point the engine returns 480 hr for base sample workload (hours).
  • At this operating point the engine returns 35 % for revision and rework allowance applied.
  • At this operating point the engine returns 0.25 pieces / min for sample completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where revision and rework allowance sits at 30% and the headline result is 624 hr, this scenario comes in 3.85% above the baseline at 648 hr.
  • A figure at this level is achievable when revision and rework allowance is genuinely sustained, not just peaked for a shift. It assumes one average completion rate; complex constructions like welted or hand-stitched samples take far longer than the average and may need a separate estimate.

Results at a glance

  • Required sample hours (with revisions): 648 hr (headline result)
  • Base sample workload (hours): 480 hr
  • Revision and rework allowance applied: 35 %
  • Sample completion rate: 0.25 pieces / min
