Tooling, Fixtures, Dies & Mold Economics worked example

Tooling Risk Score with tooling failure severity rating of 15 score: a worked example

What does the result look like when tooling failure severity rating reaches 15 score? The full calculation is worked below with real intermediate numbers. Use it when tooling risk in tooling, fixtures, dies and mold economics needs a defensible ranking against other tooling, fixtures, dies and mold economics risks for the next review.

The inputs for this scenario

  • Tooling failure severity rating (1-10): 15 score (raised for this scenario; the documented default is 6)
  • Tooling failure occurrence likelihood (1-10): 4 score (unchanged)
  • Tooling failure detection difficulty (1-10): 3 score (unchanged)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where tooling failure severity rating 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 tooling failure severity rating is genuinely sustained, not just peaked for a shift. RPN treats a 6x4x3 and a 9x2x4 as roughly equal even though a severity-9 failure (scrapped batch, safety) usually warrants action regardless of the product; always let high severity override a low total.

Results at a glance

  • Tooling risk score: 8.15 score (headline result)
  • Tooling risk severity score: 15 score
  • Tooling risk occurrence score: 4 score
