ORDREL / OEE
OEE & loss explorer
See how your equipment performs—and where productive time goes.
Exclude only time when production was not intended. Include changeovers and other stops within planned production. Do not subtract the same stop twice.
Use the fastest achievable speed for this product and equipment. An observed average or a labour rate is not an ideal equipment speed.
Good output passes first time without rework. Use the same measure for total, good and ideal speed.
Explain the stop time
Optional. Use non-overlapping stop durations. Unassigned stop time stays visible.
Explore recovering stop time
Scenario only: recovered minutes run at this period’s performance and first-pass yield. This assumes stable product, quality and speed.
Fictional example · replace every input with your measurements.
Method, boundaries & sources
Availability = run ÷ planned time. Performance = total ÷ (ideal rate × run time). Quality = good ÷ total. OEE = ideal time for good output ÷ planned time. Unavailable factors are shown as —.
Losses use equivalent minutes: recorded stops; run minus ideal time for all output; ideal time for rejects/rework; and ideal time for good output. They sum to planned production time.
One product, one equipment boundary, one period. For different ideal speeds, save separate runs; do not average their OEE percentages. Use Staffing for labour workload and service capacity.
