Should I set the target at demonstrated OEE or at our OEE goal?

At the OEE the line has demonstrated over recent comparable shifts. A goal the line has not yet reached gets missed hour after hour, so a miss stops pointing at a real problem. Raise the target as demonstrated OEE rises.

What target do I post for an hour with a break in it?

Scale the hourly board target by the minutes the line runs in that hour. At the defaults, an hour with a 15-minute break gets 18 × 45 ÷ 60 = 13.5 units.

Should planned changeovers come out of the shift length?

Not if your OEE counts them. OEE treats changeovers as stop time inside planned production time, so subtracting them here as well lowers the target twice. Take out only time with no production planned, such as breaks and meetings.

Why is the target so far below the line's rated speed?

Rated speed gives the output at 100% OEE; the gap is the stops, slow cycles and rejects your OEE records. At the defaults the line could make 180 units at rated speed; its demonstrated 75% OEE supports 135.

Shift Output Target Calculator

Set the number to post on the production board for a shift, and for each hour, from the OEE your line has demonstrated. You need shift length, breaks, ideal cycle time, OEE and the scheduled quantity.

What this calculator does

The shift and hourly output targets your line can hold at its demonstrated OEE, checked against the schedule.

Formula used

Net available time = shift length − breaks and meetings
Output at 100% OEE = net available time ÷ ideal cycle time
Shift output target = output at 100% OEE × demonstrated OEE % ÷ 100
Hourly board target = 60 ÷ ideal cycle time × OEE % ÷ 100
Surplus = target − scheduled quantity; OEE the schedule needs = scheduled quantity × ideal cycle time ÷ net available time × 100

Inputs explained

Shift Length: Scheduled minutes from shift start to shift end.
Breaks and Meetings: Minutes with no production planned: breaks, meals, start-up meeting.
Ideal Cycle Time: Fastest sustained cycle per unit, the one your OEE is built on.
Demonstrated OEE: Average OEE over recent comparable shifts, not the goal.
Scheduled Quantity: Good units the production plan asks from this shift.

How to use the result

Best suited to filling in the hour-by-hour production board, checking a weekly plan shift by shift, setting targets for a shortened shift.
For a product mix, work out each run separately or use a demand-weighted ideal cycle time. Recent OEE predicts an average shift; a start-up or new-product shift can run well below it.

Current U.S. benchmarks

U.S. manufacturing runs at 75.7% of capacity (Federal Reserve, Aug 2026). New factory orders are up 8.5% year over year (Census).
