Obsolescence Risk Score with mission or program impact severity of 3 score: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop mission or program impact severity to 3 score, then walk the calculation through step by step. Score DMSMS and lifecycle risk for defense electronics components, embedded boards, displays, processors, connectors, and power supplies.

The inputs for this scenario

  • Mission or program impact severity: 3 score (the input this scenario stresses; the baseline uses 6)
  • Obsolescence occurrence likelihood: 4 score (held at the documented default)
  • Detection and mitigation difficulty: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: DMSMS obsolescence risk score = mission impact severity × obsolescence occurrence likelihood × detection and mitigation difficulty.
  • DMSMS obsolescence risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Mission or program impact severity works out to 3 score at these inputs.
  • Obsolescence occurrence likelihood works out to 4 score at these inputs.
  • Detection and mitigation difficulty works out to 3 score at these inputs.

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 26.37% below the baseline at 3.35 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to mission or program impact severity, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It is a relative ranking tool, not an absolute probability; scores are only comparable when every component is scored on the same defined scale by the same criteria.

Results at a glance

  • DMSMS obsolescence risk score: 3.35 score (headline result)
