Service Readiness Score with service impact score of 4 score: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop service impact score to 4 score, then walk the calculation through step by step. Score service readiness risk using installed base impact, service demand likelihood, and readiness control weakness.

The inputs for this scenario

  • Service impact score (severity): 4 score (the input this scenario stresses; the baseline uses 8)
  • Expected service demand score (occurrence): 5 score (held at the documented default)
  • Readiness control weakness score (detection): 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Service readiness risk score = service impact score × expected service demand score × readiness control weakness score.
  • Service readiness risk score works out to 4.1 score at these inputs, and this is the headline figure for the scenario.
  • Service impact score works out to 4 score at these inputs.
  • Expected service demand score works out to 5 score at these inputs.
  • Readiness control weakness score works out to 3 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where service impact score sits at 8 score and the headline result is 5.7 score, this scenario comes in 28.07% below the baseline at 4.1 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to service impact score, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Like any RPN multiplication, it can hide a critical single-dimension risk: a severity-10 safety gap and a low-severity nuisance can land at similar products if the other ratings differ, so always read the three sub-scores, not just the headline.

Results at a glance

  • Service readiness risk score: 4.1 score (headline result)
  • Service impact score: 4 score
  • Expected service demand score: 5 score
  • Readiness control weakness score: 3 score
