Maintenance Planning Coverage at 65% target planning coverage: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target planning coverage to 65%, then walk the calculation through step by step. Measure how much upcoming maintenance work has approved job plans, parts, labor estimates, and scheduling information ready.

The inputs for this scenario

  • Work orders with complete job plans: 230 count (held at the documented default)
  • Work orders requiring planning: 275 count (held at the documented default)
  • Target planning coverage: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: Maintenance Planning Coverage rate = work orders with complete job plans ÷ work orders requiring planning × 100.
  • Maintenance Planning Coverage rate works out to 83.64 % at these inputs, and this is the headline figure for the scenario.
  • Maintenance Planning Coverage gap to target works out to -18.64 points at these inputs.
  • work orders with complete job plans works out to 230 count at these inputs.
  • work orders requiring planning works out to 275 count at these inputs.

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 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target planning coverage, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It counts whether a plan exists, not whether the plan is high quality — a complete but inaccurate job plan still counts as covered.

Results at a glance

  • Maintenance Planning Coverage rate: 83.64 % (headline result)
