Schedule Adherence Cost Impact at 54% schedule-attributable share: a worked example

This worked example runs the schedule adherence cost impact numbers for a tougher week than the baseline: 54% schedule-attributable share instead of the typical 75%. Estimate the cost impact of schedule adherence misses from missed orders, cost per miss, adherence responsibility, and fixed expediting cost.

The inputs for this scenario

  • Missed scheduled orders or hours: 18 orders or hr (held at the documented default)
  • Cost per schedule miss: 320 $ / miss (held at the documented default)
  • Schedule-attributable share: 54 % (the input this scenario stresses; the baseline uses 75)
  • Expedite and replanning cost: 850 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Adherence-attributable impact = missed scheduled orders or hours × cost per miss × schedule-attributable share.
  • Schedule adherence cost impact works out to 3,960 $ adherence impact at these inputs, and this is the headline figure for the scenario.
  • Cost per schedule miss works out to 220 $ / miss at these inputs.
  • Adherence-attributable impact works out to 3,110 $ adherence impact at these inputs.
  • Expedite and replanning cost works out to 850 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where schedule-attributable share sits at 75% and the headline result is 5,170 $ adherence impact, this scenario comes in 23.4% below the baseline at 3,960 $ adherence impact.
  • Use it in a weekly or monthly adherence review, when building a business case for APS or planning improvements, or after a bad week to size the damage. 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.
