Desalination & Membrane Water Treatment Equipment worked example

Membrane Supplier Risk Score with membrane supply failure severity of 15 score: a worked example

What does the result look like when membrane supply failure severity reaches 15 score? The full calculation is worked below with real intermediate numbers. Use it when membrane supplier risk in desalination and membrane water treatment equipment needs a defensible ranking against other desalination and membrane water treatment equipment risks for the next review.

The inputs for this scenario

  • Membrane supply failure severity (1-10): 15 score (raised for this scenario; the documented default is 6)
  • Likelihood of supplier non-conformance (1-10): 4 score (unchanged)
  • Inability to detect a defect before install (1-10): 3 score (unchanged)

Working through the calculation

  • Applying the documented formula (Membrane equipment supplier risk score = supplier impact severity score × supplier issue occurrence score × supplier detection control score) to the inputs above produces each figure below.
  • At this operating point the engine returns 8.15 score for membrane equipment supplier risk score, the number this scenario is built around.
  • At this operating point the engine returns 15 score for supplier impact severity score.
  • At this operating point the engine returns 4 score for supplier issue occurrence score.
  • At this operating point the engine returns 3 score for supplier detection control score.

How this compares with the baseline

  • Against the tool's baseline example, where membrane supply failure 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.
  • A figure at this level is achievable when membrane supply failure severity is genuinely sustained, not just peaked for a shift. The number is ordinal, not financial — a score of 120 is not literally twice the dollar exposure of 60, and identical scores can hide very different severity profiles, so always inspect the severity factor behind a high number.

Results at a glance

  • Membrane equipment supplier risk score: 8.15 score (headline result)
  • Supplier impact severity score: 15 score
  • Supplier issue occurrence score: 4 score
  • Supplier detection control score: 3 score
