Supplier Quality, Development & Audits worked example

Approved Supplier Coverage at 99% target approved-supplier coverage rate: a worked example

This scenario runs the approved supplier coverage calculation on the strong side: 99% target approved-supplier coverage rate, with every other input held at its documented default. Use it when approved supplier coverage in supplier quality, development and audits needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Suppliers meeting approval requirements: 8 count (unchanged)
  • Total active suppliers in scope: 250 count (unchanged)
  • Target approved-supplier coverage rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Approved supplier coverage rate = approved supplier coverage count ÷ total approved supplier coverage population × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 3.2 % for approved supplier coverage rate, the number this scenario is built around.
  • At this operating point the engine returns 95.8 points for approved supplier coverage gap to target.
  • At this operating point the engine returns 8 count for approved supplier coverage count.
  • At this operating point the engine returns 250 count for total approved supplier coverage population.

How this compares with the baseline

  • Against the tool's baseline example, where target approved-supplier coverage rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • Use it for supply-base audits, ISO/IATF readiness, and quarterly reviews of AVL completeness. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.
