PLM, BOM & Digital Thread worked example

Design Release Readiness Score with severity of the design escape if released as-is of 3 score: a worked example

This worked example runs the design release readiness score numbers for a tougher week than the baseline: severity of the design escape if released as-is of 3 score instead of the typical 6 score. Estimate design release readiness for plm, bom and digital thread using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Severity of the design escape if released as-is (1-10): 3 score (the input this scenario stresses; the baseline uses 6)
  • Likelihood the design issue occurs in production (1-10): 4 score (held at the documented default)
  • Ability to detect the issue before release (1-10): 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Design release readiness risk score = design release readiness severity score × design release readiness occurrence score × design release readiness detection score.
  • Design release readiness risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Design release readiness severity score works out to 3 score at these inputs.
  • Design release readiness occurrence score works out to 4 score at these inputs.
  • Design release readiness detection score works out to 3 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where severity of the design escape if released as-is sits at 6 score and the headline result is 4.55 score, this scenario comes in 26.37% below the baseline at 3.35 score.
  • Use it at each design-release gate or ECN sign-off to rank open design risks and decide whether a revision is release-ready or must return to engineering. 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.

Results at a glance

  • Design release readiness risk score: 3.35 score (headline result)
  • Design release readiness severity score: 3 score
  • Design release readiness occurrence score: 4 score
  • Design release readiness detection score: 3 score

Run it with your numbers

  • To rerun this with your own numbers, open the live Design Release Readiness Score calculator, set severity of the design escape if released as-is to your actual value, and adjust the remaining inputs to match your operation.
