Delivery Risk with schedule-slip severity of 3 score: a worked example in process skids, modular equipment & packaged plants

Here is what the math looks like when conditions slip. We hold every other input steady and drop schedule-slip severity to 3 score, then walk the calculation through step by step. Delivery Risk rolls three judgments about a skid package's schedule into a single weighted score so project teams can rank which jobs threaten on-time delivery.

The inputs for this scenario

  • Schedule-slip severity: 3 score (the input this scenario stresses; the baseline uses 6)
  • Slip likelihood: 4 score (held at the documented default)
  • Slip detectability: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Delivery Risk risk score = severity × 0.40 + occurrence × 0.35 + detection × 0.25.
  • Risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Severity works out to 3 score at these inputs.
  • Occurrence works out to 4 score at these inputs.
  • Detection works out to 3 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where schedule-slip 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 schedule-slip severity, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The score is only as good as the 1-to-10 judgments behind it; inconsistent scoring across estimators makes cross-project comparison unreliable.
