Production Ramp, Scale-Up & Launch Readiness worked example

Scale-Up Risk Score with severity of scale-up failure impact of 3 score: a worked example

Suppose severity of scale-up failure impact falls to 3 score. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate scale-up risk for production ramp, scale-up and launch readiness 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 scale-up failure impact: 3 score (the input this scenario stresses; the baseline uses 6)
  • Likelihood the scale-up issue occurs: 4 score (held at the documented default)
  • Ability to detect the issue before escape: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Scale-up risk score = scale-up risk severity score × scale-up risk occurrence score × scale-up risk detection score.
  • Scale-up risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Scale-up risk severity score works out to 3 score at these inputs.
  • Scale-up risk occurrence score works out to 4 score at these inputs.
  • Scale-up risk 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 scale-up failure impact 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.
  • It multiplies severity, occurrence, and detection scores into a single risk priority number, the same structure as an FMEA RPN, for a given scale-up failure mode. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
