Supplier Quality, Development & Audits worked example

Supplier Corrective Action Cycle Time at 12% review, escalation, and handoff allowance: a worked example

What does the result look like when review, escalation, and handoff allowance reaches 12%? The full calculation is worked below with real intermediate numbers. Use it when supplier corrective action cycle time in supplier quality, development and audits is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Open supplier corrective actions (8Ds) in the queue: 120 units (unchanged)
  • SCARs closed per minute of reviewer effort: 12 units / min (unchanged)
  • Review, escalation, and handoff allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where review, escalation, and handoff allowance sits at 10% and the headline result is 11 hr, this scenario comes in 1.82% above the baseline at 11.2 hr.
  • A figure at this level is achievable when review, escalation, and handoff allowance is genuinely sustained, not just peaked for a shift. It models steady reviewer throughput; a queue full of stalled 8Ds waiting on supplier data can blow past this estimate because the delay lives at the supplier, not in your review capacity.

Results at a glance

  • Required supplier corrective action cycle time: 11.2 hr (headline result)
  • Base supplier corrective action cycle time: 10 hr
  • Supplier corrective action cycle time allowance applied: 12 %
  • Supplier corrective action cycle time completion rate: 12 pieces / min
