Schedule Attainment Rate at 99% target attainment rate: a worked example

This scenario runs the schedule attainment rate calculation on the strong side: 99% target attainment rate, with every other input held at its documented default. Use this calculator to measure how reliably your production meets the planned schedule. Low attainment signals disruptions, planning errors, or capacity shortfalls that need investigation.

The inputs for this scenario

  • Actual units completed: 185 units (unchanged)
  • Planned (scheduled) units: 200 units (unchanged)
  • Target attainment rate: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Schedule Attainment = (Actual / Planned) x 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 92.5 % for schedule attainment rate (%), the number this scenario is built around.
  • At this operating point the engine returns 6.5 points for gap to target attainment.
  • At this operating point the engine returns 185 count for actual units completed.
  • At this operating point the engine returns 200 count for planned units.

How this compares with the baseline

  • Against the tool's baseline example, where target attainment rate sits at 95% and the headline result is 92.5 %, this scenario lands almost exactly on the baseline at 92.5 %.
  • Use it at the close of every shift, day, or week to grade execution against the published production schedule and to trigger recovery actions when you fall short. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Schedule attainment rate (%): 92.5 % (headline result)
  • Gap to target attainment: 6.5 points
  • Actual units completed: 185 count
  • Planned units: 200 count

Run it with your numbers

  • Every input above is editable in the live Schedule Attainment Rate calculator, which recalculates instantly and can be shared with the inputs intact.
