Raw Material Shelf Life Risk with shelf-life failure impact severity of 4 score: a worked example

This worked example runs the raw material shelf life risk numbers for a tougher week than the baseline: shelf-life failure impact severity of 4 score instead of the typical 8 score. Score raw material shelf-life risk from impact severity, likelihood of expiry or degradation, and detectability before use.

The inputs for this scenario

  • Shelf-life failure impact severity: 4 score (the input this scenario stresses; the baseline uses 8)
  • Expiry or degradation likelihood: 5 score (held at the documented default)
  • Pre-use detection difficulty: 4 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Raw Material Shelf Life Risk = shelf-life impact severity × expiry or degradation likelihood × pre-use detection difficulty.
  • raw material shelf life risk works out to 4.35 score at these inputs, and this is the headline figure for the scenario.
  • shelf-life impact severity works out to 4 score at these inputs.
  • expiry or degradation likelihood works out to 5 score at these inputs.
  • pre-use detection difficulty works out to 4 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where shelf-life failure impact severity sits at 8 score and the headline result is 5.95 score, this scenario comes in 26.89% below the baseline at 4.35 score.
  • Use it when ranking raw materials for retest frequency, FEFO rotation rules, storage upgrades or supplier shelf-life agreements across a chemical or coatings store. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • raw material shelf life risk: 4.35 score (headline result)
  • shelf-life impact severity: 4 score
  • expiry or degradation likelihood: 5 score
  • pre-use detection difficulty: 4 score
