PPAP Review Workload at 7.2% element deep-dive and dimensional-check allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop element deep-dive and dimensional-check allowance to 7.2%, then walk the calculation through step by step. Estimate ppap review workload for supplier quality, development and audits using production-ready inputs so teams can plan labor hours, schedule the work, or check whether the job fits the available shift time.

The inputs for this scenario

  • PPAP submissions awaiting review: 120 units (held at the documented default)
  • PPAP packages a reviewer clears per minute: 12 units / min (held at the documented default)
  • Element deep-dive and dimensional-check 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 ppap review workload time = ppap review workload workload รท ppap review workload completion rate.
  • Required ppap review workload time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base ppap review workload time works out to 10 hr at these inputs.
  • Ppap review workload allowance applied works out to 7.2 % at these inputs.
  • Ppap review workload completion rate works out to 12 pieces / min at these inputs.

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 2.55% below the baseline at 10.72 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to element deep-dive and dimensional-check allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a consistent submission complexity; a batch mixing simple Level 1 warrants with full Level 3 packages (PSW, dimensional results, PFMEA, MSA) will not fit a single throughput rate well.

Results at a glance

  • Required ppap review workload time: 10.72 hr (headline result)
  • Base ppap review workload time: 10 hr
  • Ppap review workload allowance applied: 7.2 %
  • Ppap review workload completion rate: 12 pieces / min
