Supplier Drawing Access Coverage at 99% target drawing-access coverage rate: a worked example

What does the result look like when target drawing-access coverage rate reaches 99%? The full calculation is worked below with real intermediate numbers. Use it when supplier drawing access coverage in plm, bom and digital thread needs a clean rate and gap-to-target you can put on a tier board.

The inputs for this scenario

  • Suppliers with current controlled-drawing access: 8 count (unchanged)
  • Total active suppliers needing drawing access: 250 count (unchanged)
  • Target drawing-access coverage rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where target drawing-access coverage rate sits at 95% and the headline result is 3.2 %, this scenario lands almost exactly on the baseline at 3.2 %.
  • A figure at this level is achievable when target drawing-access coverage rate is genuinely sustained, not just peaked for a shift. It counts suppliers, not spend or part criticality. A 3.2% coverage rate can look catastrophic even if the connected suppliers happen to cover your highest-volume parts, so weight the result against risk.
