OEE & Factory Performance worked example

Line Efficiency at 99% target efficiency: a worked example in oee & factory performance

This scenario runs the line efficiency calculation on the strong side: 99% target efficiency, with every other input held at its documented default. Use it to track how close a line runs to its proven best in OEE & Factory Performance.

The inputs for this scenario

  • Actual good output: 850 units (unchanged)
  • Demonstrated capacity: 1,000 units (unchanged)
  • Target efficiency: 99 % (raised for this scenario; the documented default is 90)

Working through the calculation

  • Applying the documented formula (Line efficiency = actual good output รท demonstrated capacity) to the inputs above produces each figure below.
  • At this operating point the engine returns 85 % for line efficiency, the number this scenario is built around.
  • At this operating point the engine returns 14 points for gap to target.
  • At this operating point the engine returns 850 value for actual good output.
  • At this operating point the engine returns 1,000 value for demonstrated capacity.

How this compares with the baseline

  • Against the tool's baseline example, where target efficiency sits at 90% and the headline result is 85 %, this scenario lands almost exactly on the baseline at 85 %.
  • Use it at shift handover or weekly performance reviews to judge a line against its own proven capability rather than a vendor nameplate rate. 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

  • Line efficiency: 85 % (headline result)
  • Gap to target: 14 points
  • Actual good output: 850 value
  • Demonstrated capacity: 1,000 value

Run it with your numbers

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