Space Payload & Avionics Manufacturing worked example

Inspection Bottleneck with inspection defect severity of 15 score: a worked example in space payload & avionics manufacturing

Push inspection defect severity up to 15 score and the picture changes. This example computes every intermediate figure at that operating point. Use it when inspection bottleneck in space payload and avionics manufacturing needs a defensible ranking against other space payload and avionics manufacturing risks for the next review.

The inputs for this scenario

  • Inspection defect severity (impact if missed): 15 score (raised for this scenario; the documented default is 6)
  • Inspection defect occurrence frequency: 4 score (unchanged)
  • Inspection escape detectability: 3 score (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where inspection defect 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.
  • It multiplies inspection severity, occurrence, and detection scores into a single Risk Priority Number that ranks which inspection bottleneck to fix first. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Inspection bottleneck risk score: 8.15 score (headline result)
  • Inspection bottleneck severity score: 15 score
  • Inspection bottleneck occurrence score: 4 score
  • Inspection bottleneck detection score: 3 score
