A useful production board answers a specific question: have we made the accepted output planned for this point in the shift? Compare target and actual on the same time boundary, then use the gap to decide what needs checking. A daily total alone cannot show when the plan began to drift.
Agree what the two numbers mean
Define the line, product, work order, unit and shift boundary before comparing output. The target is accepted output expected by the review time. Actual is accepted output recorded by that same time. Vorne’s production-target guide describes comparing accumulated targets with accumulated actual output.
Keep total pieces, rejects and accepted pieces separate. If one board counts gross output while another counts good output, an apparent disagreement may be a definition problem. Record when units become accepted, including how a later quality correction affects the original count.
Build the target from the approved schedule
Split the shift into review intervals and assign a planned good-unit count to each. Sum those interval counts to create the cumulative target. Use the actual approved timing of breaks, changeovers and product runs; dividing the full shift target evenly across every clock hour can create false alarms during a planned stop.
Record the original plan and any approved revision. Changing a target after a miss without retaining the earlier version makes performance hard to explain. For different products, preserve separate counts or use a defined common planning measure rather than silently adding unlike units.
Worked example: a four-hour production board
This hypothetical line makes one product from 9 am to 1 pm. Its approved planning rate is 120 good units per running hour. Two intervals each contain a 15-minute planned break, leaving a target of 420 good units across the window.
| Interval | Planned units | Actual units | Cumulative target | Cumulative actual | Behind plan |
|---|---|---|---|---|---|
| 9–10 am | 120 | 110 | 120 | 110 | 10 |
| 10–11 am: 15-minute break | 90 | 85 | 210 | 195 | 15 |
| 11 am–noon | 120 | 125 | 330 | 320 | 10 |
| Noon–1 pm: 15-minute break | 90 | 85 | 420 | 405 | 15 |
The third interval exceeds its own target, yet the cumulative board remains 10 units behind. At 11 am, attainment is 195 ÷ 210 × 100 = 92.9%. At the end of the window it is 405 ÷ 420 × 100 = 96.4%. Neither percentage explains the loss cause by itself.
Show the gap without hiding the time boundary
Count variance = cumulative actual − cumulative target. A negative result means behind plan. Attainment = cumulative actual ÷ cumulative target × 100. When the cumulative target is zero, report attainment as unavailable rather than dividing by zero.
Display the review time beside these results. “15 behind at 11 am” is more useful than an unexplained red percentage. Retain interval output as well as cumulative output: the interval shows whether conditions improved, while the cumulative view shows whether the earlier gap remains.
Check freshness before interpreting a miss
A number last updated 20 minutes ago cannot support the same conclusion as a current count. Show the source time, collection method and any missing interval. If operators enter counts manually, define who updates the board and how often. If counts arrive automatically, reconcile them against accepted output during an initial check.
Keep corrections visible. A late reject entry or duplicate counter event can change actual output without a physical production change. Identify the correction, preserve its time and review the comparison again.
Turn the review into a specific next action
Use the gap to ask what happened during the interval: a recorded stop, lower running pace, missing material or a quality issue. Then document one action with an owner, expected completion time and evidence to check at the next review. Short Interval Control provides a structured approach to reviewing recent performance and choosing focused actions.
At handover, carry forward unresolved issues and the last trustworthy count. A useful note states the current gap, relevant observation, action owner and next check. “Production is behind” leaves the next team to repeat the investigation.
Know what the board can and cannot tell you
Target-versus-actual tracking measures progress against a plan. It does not establish that the target was feasible, identify the root cause, or predict the final shift result. Check the planning assumptions when the same gap repeatedly appears.

Practical questions
Should I compare actual output with the full shift target every hour?
Show the full target for context, but compare progress with the cumulative target for the review time. Comparing the first hour with the complete shift total does not measure whether that hour followed the plan.
What if the target changes during the shift?
Record the approved revision and its time. Preserve the original plan so reviewers can distinguish an operating miss from a planning change.
Does 100% attainment mean the line is running at ideal speed?
No. Attainment compares output with the approved target. The target may use a planning rate that differs from the ideal rate used for OEE performance.
