Maintenance Planning Coverage at 99% target planning coverage: a worked example

What does the result look like when target planning coverage reaches 99%? The full calculation is worked below with real intermediate numbers. a maintenance or asset-management team needs to improve schedule readiness, reduce delays, and focus planner effort before weekly scheduling for a planned work queue

The inputs for this scenario

  • Work orders with complete job plans: 230 count (unchanged)
  • Work orders requiring planning: 275 count (unchanged)
  • Target planning coverage: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Maintenance Planning Coverage rate = work orders with complete job plans ÷ work orders requiring planning × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 83.64 % for maintenance planning coverage rate, the number this scenario is built around.
  • At this operating point the engine returns 15.36 points for maintenance planning coverage gap to target.
  • At this operating point the engine returns 230 count for work orders with complete job plans.
  • At this operating point the engine returns 275 count for work orders requiring planning.

How this compares with the baseline

  • Against the tool's baseline example, where target planning coverage sits at 90% and the headline result is 83.64 %, this scenario lands almost exactly on the baseline at 83.64 %.
  • A figure at this level is achievable when target planning coverage is genuinely sustained, not just peaked for a shift. It counts whether a plan exists, not whether the plan is high quality — a complete but inaccurate job plan still counts as covered.
