NPI, DFM/DFA & Engineering Change worked example

BOM Maturity Score with bom risk severity rating of 15 score: a worked example in npi, dfm/dfa & engineering change

This scenario runs the bom maturity score calculation on the strong side: bom risk severity rating of 15 score, with every other input held at its documented default. Use it when bom maturity in npi, dfm/dfa and engineering change needs a defensible ranking against other npi, dfm/dfa and engineering change risks for the next review.

The inputs for this scenario

  • BOM risk severity rating: 15 score (raised for this scenario; the documented default is 6)
  • BOM risk occurrence rating: 4 score (unchanged)
  • BOM risk detection rating: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Bom maturity risk score = bom maturity severity score × bom maturity occurrence score × bom maturity detection score) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for bom maturity risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for bom maturity severity score.
  • At this operating point the engine returns 4 score for bom maturity occurrence score.
  • At this operating point the engine returns 3 score for bom maturity detection score.

How this compares with the baseline

  • Against the tool's baseline example, where bom risk severity rating sits at 6 score and the headline result is 4.55 score, this scenario comes in 79.12% above the baseline at 8.15 score.
  • Use it during BOM reviews and design-release gates to triage which bill-of-materials risks to mitigate first. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Bom maturity risk score: 8.15 score (headline result)
