Supplier Quality, Development & Audits worked example

Supplier Change Notice Workload at 12% setup, handling, and delay allowance: a worked example

Push setup, handling, and delay allowance up to 12% and the picture changes. This example computes every intermediate figure at that operating point. Use it when supplier change notice workload in supplier quality, development and audits is changing rate or allowance and you want to see the impact.

The inputs for this scenario

  • Change notices to review this period: 120 units (unchanged)
  • SCN review throughput per reviewer: 12 units / min (unchanged)
  • Setup, handling, and delay allowance: 12 % (raised for this scenario; the documented default is 10)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where setup, handling, and delay 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 converts a count of change notices and a review rate into required reviewer hours, including a setup and delay allowance. 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.
