Production Ramp, Scale-Up & Launch Readiness worked example

Scale-Up Risk Score with severity of scale-up failure impact of 15 score: a worked example

This scenario runs the scale-up risk score calculation on the strong side: severity of scale-up failure impact of 15 score, with every other input held at its documented default. Use it when scale-up risk in production ramp, scale-up and launch readiness needs a defensible ranking against other production ramp, scale-up and launch readiness risks for the next review.

The inputs for this scenario

  • Severity of scale-up failure impact: 15 score (raised for this scenario; the documented default is 6)
  • Likelihood the scale-up issue occurs: 4 score (unchanged)
  • Ability to detect the issue before escape: 3 score (unchanged)

Working through the calculation

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

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 79.12% above the baseline at 8.15 score.
  • Use it during PFMEA reviews and scale-up planning to rank failure modes and decide which get containment or design action before ramp. 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

  • Scale-up risk score: 8.15 score (headline result)
  • Scale-up risk severity score: 15 score
  • Scale-up risk occurrence score: 4 score
  • Scale-up risk detection score: 3 score
