Connected Work Order Coverage at 65% target mes coverage rate: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop target mes coverage rate to 65%, then walk the calculation through step by step. Measure what percentage of work orders are managed through the MES rather than paper or manual systems, tracking your digital adoption progress.

The inputs for this scenario

  • Work orders executed through MES: 340 orders (held at the documented default)
  • Total work orders issued: 425 orders (held at the documented default)
  • Target MES coverage rate: 65 % (the input this scenario stresses; the baseline uses 90)

Working through the calculation

  • The calculation starts from the formula this tool documents: MES coverage rate = (work orders through MES / total work orders issued) x 100.
  • MES work order coverage rate works out to 80 % at these inputs, and this is the headline figure for the scenario.
  • Gap to MES coverage target works out to -15 points at these inputs.
  • Work orders through MES works out to 340 count at these inputs.
  • Total work orders issued works out to 425 count at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where target mes coverage rate sits at 90% and the headline result is 80 %, this scenario lands almost exactly on the baseline at 80 %.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to target mes coverage rate, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Coverage counts orders touched by the MES, not data quality within them; an order can be counted as covered while operators skip steps or backfill data after the fact.

Results at a glance

  • MES work order coverage rate: 80 % (headline result)
  • Gap to MES coverage target: -15 points
  • Work orders through MES: 340 count
  • Total work orders issued: 425 count
