PPAP Review Workload at 12% element deep-dive and dimensional-check allowance: a worked example

Push element deep-dive and dimensional-check allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when ppap review workload in supplier quality, development and audits needs a defensible run time before a quote goes out.

The inputs for this scenario

  • PPAP submissions awaiting review: 120 units (unchanged)
  • PPAP packages a reviewer clears per minute: 12 units / min (unchanged)
  • Element deep-dive and dimensional-check allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

  • Applying the documented formula (Base ppap review workload time = ppap review workload workload รท ppap review workload completion rate) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.2 hr for required ppap review workload time, the number this scenario is built around.
  • At this operating point the engine returns 10 hr for base ppap review workload time.
  • At this operating point the engine returns 12 % for ppap review workload allowance applied.
  • At this operating point the engine returns 12 pieces / min for ppap review workload completion rate.

How this compares with the baseline

  • Against the tool's baseline example, where element deep-dive and dimensional-check allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • It divides the number of PPAP submissions by reviewer throughput and applies an allowance to yield the total labor-hours needed to review the batch. 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.
