Work Order Completion Rate at 68% schedule compliance target: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop schedule compliance target to 68%, then walk the calculation through step by step. Measure the percentage of scheduled work orders completed on time within the planning period.

The inputs for this scenario

  • Completed on-time work orders: 184 work orders (held at the documented default)
  • Scheduled work orders: 210 work orders (held at the documented default)
  • Schedule compliance target: 68 % (the input this scenario stresses; the baseline uses 95)

Working through the calculation

  • The calculation starts from the formula this tool documents: Work-order completion rate = completed on-time work orders ÷ scheduled work orders × 100.
  • Work-Order Completion Rate works out to 87.62 % at these inputs, and this is the headline figure for the scenario.
  • Gap to Schedule Target works out to -19.62 points at these inputs.
  • Completed on-Time Work Orders works out to 184 count at these inputs.
  • Scheduled Work Orders works out to 210 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where schedule compliance target sits at 95% and the headline result is 87.62 %, this scenario lands almost exactly on the baseline at 87.62 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to schedule compliance target, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It counts work orders, not labor hours or job value, so a backlog of small jobs and a missed major shutdown task can look identical.

Results at a glance

  • Work-Order Completion Rate: 87.62 % (headline result)
