Tooling, Fixtures, Dies & Mold Economics worked example

Tooling Risk Score with tooling failure severity rating of 3 score: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop tooling failure severity rating to 3 score, then walk the calculation through step by step. Estimate tooling risk for tooling, fixtures, dies and mold economics using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Tooling failure severity rating (1-10): 3 score (the input this scenario stresses; the baseline uses 6)
  • Tooling failure occurrence likelihood (1-10): 4 score (held at the documented default)
  • Tooling failure detection difficulty (1-10): 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Tooling risk score = tooling risk severity score × tooling risk occurrence score × tooling risk detection score.
  • Tooling risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Tooling risk severity score works out to 3 score at these inputs.
  • Tooling risk occurrence score works out to 4 score at these inputs.
  • Tooling risk detection score works out to 3 score at these inputs.

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 26.37% below the baseline at 3.35 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to tooling failure severity rating, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. 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.
