Obsolescence Risk Score with mission or program impact severity of 15 score: a worked example

This scenario runs the obsolescence risk score calculation on the strong side: mission or program impact severity of 15 score, with every other input held at its documented default. Use it when obsolescence risk in defense electronics and ruggedized systems needs a defensible ranking against other defense electronics and ruggedized systems risks for the next review.

The inputs for this scenario

  • Mission or program impact severity: 15 score (raised for this scenario; the documented default is 6)
  • Obsolescence occurrence likelihood: 4 score (unchanged)
  • Detection and mitigation difficulty: 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (DMSMS obsolescence risk score = mission impact severity × obsolescence occurrence likelihood × detection and mitigation difficulty) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for dmsms obsolescence risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for mission or program impact severity.
  • At this operating point the engine returns 4 score for obsolescence occurrence likelihood.
  • At this operating point the engine returns 3 score for detection and mitigation difficulty.

How this compares with the baseline

  • Against the tool's baseline example, where mission or program impact severity 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 obsolescence reviews, supplier risk assessments, and bill-of-materials triage to rank components for last-time-buys, redesign, or substitution. 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

  • DMSMS obsolescence risk score: 8.15 score (headline result)
