Maintenance Schedule Compliance at 61% target schedule compliance for the site: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target schedule compliance for the site to 61%, then walk the calculation through step by step. Measure schedule compliance by comparing work orders completed as scheduled with the total work orders committed to the weekly plan.

The inputs for this scenario

  • Scheduled work orders completed as planned in the period: 156 count (held at the documented default)
  • Work orders on the approved weekly schedule: 190 count (held at the documented default)
  • Target schedule compliance for the site: 61 % (the input this scenario stresses; the baseline uses 85)

Working through the calculation

  • The calculation starts from the formula this tool documents: Maintenance Schedule Compliance rate = scheduled work orders completed as planned ÷ work orders on the approved schedule × 100.
  • Maintenance Schedule Compliance rate works out to 82.11 % at these inputs, and this is the headline figure for the scenario.
  • Maintenance Schedule Compliance gap to target works out to -21.11 points at these inputs.
  • scheduled work orders completed as planned works out to 156 count at these inputs.
  • work orders on the approved schedule works out to 190 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target schedule compliance for the site sits at 85% and the headline result is 82.11 %, this scenario lands almost exactly on the baseline at 82.11 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target schedule compliance for the site, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It counts completion against the approved schedule only; emergency work that was correctly prioritized still shows as a break here, so read it alongside reactive-work ratio rather than in isolation.

Results at a glance

  • Maintenance Schedule Compliance rate: 82.11 % (headline result)
  • Maintenance Schedule Compliance gap to target: -21.11 points
  • scheduled work orders completed as planned: 156 count
  • work orders on the approved schedule: 190 count
