Waste-to-Energy Equipment worked example

Installation Bottleneck with installation delay severity of 3 score: a worked example in waste-to-energy equipment

Here is what the math looks like when conditions slip. We hold every other input steady and drop installation delay severity to 3 score, then walk the calculation through step by step. Estimate installation bottleneck for waste-to-energy equipment using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Installation delay severity (impact on commissioning): 3 score (the input this scenario stresses; the baseline uses 6)
  • Installation delay occurrence (how often it recurs): 4 score (held at the documented default)
  • Installation delay detection (how easily caught pre-startup): 3 score (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where installation delay severity 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 installation delay severity, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. RPN is ordinal, not a probability or a cost — a score of 72 is not twice as bad as 36, so use it only to rank comparable risks scored on the same 1-10 scale, not to forecast delay days or dollars.

Results at a glance

  • Installation bottleneck risk score: 3.35 score (headline result)
  • Installation bottleneck severity score: 3 score
  • Installation bottleneck occurrence score: 4 score
  • Installation bottleneck detection score: 3 score
