Schedule Compression Value at 54% realizable compression confidence: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop realizable compression confidence to 54%, then walk the calculation through step by step. Estimate the value of compressing lead time from hours saved, value per hour, confidence share, and implementation cost.

The inputs for this scenario

  • Lead-time hours saved: 48 hr (held at the documented default)
  • Value per saved hour: 160 $ / hr (held at the documented default)
  • Realizable compression confidence: 54 % (the input this scenario stresses; the baseline uses 75)
  • Compression implementation cost: 1,100 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Realizable compression benefit = lead-time hours saved × value per saved hour × confidence.
  • Schedule compression value works out to 5,247 $ compression value at these inputs, and this is the headline figure for the scenario.
  • Value per saved hour works out to 109 $ / hr at these inputs.
  • Realizable compression benefit works out to 4,147 $ compression value at these inputs.
  • Compression implementation cost works out to 1,100 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where realizable compression confidence sits at 75% and the headline result is 6,860 $ compression value, this scenario comes in 23.51% below the baseline at 5,247 $ compression value.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to realizable compression confidence, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Value per saved hour is an estimate (often blended from carrying cost, expedite-fee avoidance, and revenue-pull-in); if that input is soft, the result inherits its uncertainty and should be treated as a range, not a precise figure.
