188 of 200 on time is 94%—good enough?
Depends on which twelve missed. Two key-account reprints at EUR 45k combined warrant escalation even at 94% headline.

What is On-Time Production?
On-time production is the share of production orders completed by the committed finish date—orders completed on time divided by total orders in the period. It is not schedule adherence (that compares output to the internal plan quantity) and it is not on-time delivery to the customer (that includes shipping). At PakProm d.o.o., 188 orders completed on time out of 200 production orders released in May is 94% on-time production. I track it against the original promise date, not the revised date ops entered after the slip—otherwise 94% becomes a story about moving goalposts.
Why On-Time Production matters
Late production compresses shipping, forces overtime, and breaks the promise sales gave the customer before the truck was ever loaded. At 94%, twelve orders missed the committed finish window—PakProm finished May with EUR 9,200 overtime and three key-account recovery calls. Chronic misses teach sales to pad quotes; customers learn to order elsewhere. Material shortages, engineering release delays, and quality holds all show up here before they show up in DSO. On-time production is the internal handshake between planning and the floor—weak at 88% and shipping will never consistently hit 98% no matter what logistics does.
Formula and variables
On-Time Production % = Orders Completed On Time ÷ Total Orders × 100
Orders completed on time — production orders finished by original committed finish date (define grace minutes in policy).
Total orders — production orders closed or due in the period per same scope.
Excel: =IFERROR(B2/B3*100,0)
Real business example
PakProm d.o.o. May production order close: 188 orders completed on or before the original committed finish date; 200 total production orders due in May. On-time production = 188 ÷ 200 × 100 = 94%. The twelve late orders split: five material short on laminate web, four engineering release held for revised artwork, three quality hold on registration. Two late orders were key-account reprints worth EUR 45k combined—commercial escalation within 24 hours with recovery dates sent to customers.
How to interpret the result
On-time production measures internal finish discipline against the promise date.
- 94% with revised-date tracking might look 98%—always report against original commitment.
- Segment standard repeat orders versus custom new artwork—different targets, same honesty.
- Material-related late orders belong in the same meeting as inventory stockout metrics.
- High schedule adherence with low on-time production means right quantity, wrong finish date.
Benchmark context
Repeat manufacturing on established SKUs often targets 95–98% on-time production; custom packaging with artwork cycles may run 90–94% with documented ramp rules. Compare to your own trailing four months and to the finish-date promise sales uses in CRM—not a generic 100%. PakProm holds 94% as acceptable in a heavy custom month but escalates any key-account miss regardless of headline percent.
Red flags
- On-time production below 90% two months running—overtime and customer penalties accumulate.
- 94% headline but key-account on-time below 85%—average hides contract risk.
- Late orders cluster on material code—inventory and supplier OTIF failing before ops gets blamed.
- Revised-date on-time 98% but original-date 94%—goalpost moving masks planning weakness.
- On-time production falls while WIP rises—orders started late and finished late; flow problem not capacity.
Common mistakes
- Measuring against revised finish date after slip—on-time production looks healthy while customers wait.
- Mixing production orders and sales orders in the denominator—different scope, false percent.
- Excluding orders cancelled for material—denominator should reflect released work, not only completions.
- One plant-wide number hiding a cell at 82% that feeds the constraint.
- No root-cause split—94% becomes 'we tried hard' instead of five material and four engineering fixes.
What should management do next?
- Define on-time to original customer promise; track revised-date OT separately.
- Root-cause late orders weekly—material, capacity, engineering release, quality hold.
- Report OT by standard versus custom order type with different targets.
- Feed material-related late orders to inventory KPI owner same meeting.
- Escalate any key-account miss within 24 hours with recovery date to customer.

FAQ
Original versus revised finish date—which counts?
Original for management accountability; revised for internal recovery tracking. Publish both to stop quiet goalpost moves.
How does on-time production differ from schedule adherence?
Adherence is output versus internal plan quantity; on-time production is finish date versus commitment. You can adhere to quantity and still miss date.
Custom orders drag OT—separate target?
Yes. Standard repeat 96% target, custom 90% with artwork SLA in the same dashboard.
Material late orders—who owns the fix?
Split in review: supplier delay to procurement, internal stock to inventory planner. Same meeting as stockout rate.
Summary
On-time production tracks whether orders finish by the committed date. Measure against the original promise, root-cause every miss, and escalate key accounts—headline 94% is not comfort if the twelve late orders were the ones that mattered.
