Supplier Quality, Development & Audits worked example

Approved Supplier Coverage at 68% target approved-supplier coverage rate: a worked example

This worked example runs the approved supplier coverage numbers for a tougher week than the baseline: 68% target approved-supplier coverage rate instead of the typical 95%. Estimate approved supplier coverage for supplier quality, development and audits using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Suppliers meeting approval requirements: 8 count (held at the documented default)
  • Total active suppliers in scope: 250 count (held at the documented default)
  • Target approved-supplier coverage rate: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Approved supplier coverage rate = approved supplier coverage count ÷ total approved supplier coverage population × 100.
  • Approved supplier coverage rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Approved supplier coverage gap to target works out to 64.8 points at these inputs.
  • Approved supplier coverage count works out to 8 count at these inputs.
  • Total approved supplier coverage population works out to 250 count at these inputs.

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. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
