PLM, BOM & Digital Thread worked example

Supplier Drawing Access Coverage at 68% target drawing-access coverage rate: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target drawing-access coverage rate to 68%, then walk the calculation through step by step. Estimate supplier drawing access coverage for plm, bom and digital thread using production-ready inputs so teams can track KPI performance and decide whether corrective action is needed.

The inputs for this scenario

  • Suppliers with current controlled-drawing access: 8 count (held at the documented default)
  • Total active suppliers needing drawing access: 250 count (held at the documented default)
  • Target drawing-access 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: Supplier drawing access coverage rate = supplier drawing access coverage count ÷ total supplier drawing access coverage population × 100.
  • Supplier drawing access coverage rate works out to 3.2 % at these inputs, and this is the headline figure for the scenario.
  • Supplier drawing access coverage gap to target works out to 64.8 points at these inputs.
  • Supplier drawing access coverage count works out to 8 count at these inputs.
  • Total supplier drawing access coverage population works out to 250 count at these inputs.

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 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target drawing-access coverage rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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.
