Manufacturing Project Portfolio & Capex worked example

Project Ranking Score with project impact severity of 3 score: a worked example

This worked example runs the project ranking score numbers for a tougher week than the baseline: project impact severity of 3 score instead of the typical 6 score. Estimate project ranking for manufacturing project portfolio and capex using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Project impact severity (1-10): 3 score (the input this scenario stresses; the baseline uses 6)
  • Likelihood the risk occurs (1-10): 4 score (held at the documented default)
  • Difficulty of detecting it early (1-10): 3 score (held at the documented default)

Working through the calculation

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

How this compares with the baseline

  • Against the tool's baseline example, where project impact 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.
  • Use it when ranking a backlog of projects or risks against each other and you need a defensible, repeatable ordering rather than subjective debate. 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

  • Project ranking risk score: 3.35 score (headline result)
  • Project ranking severity score: 3 score
  • Project ranking occurrence score: 4 score
  • Project ranking detection score: 3 score
