Overproduction is the waste that looks like success. A line that runs a few percent past its order shows high output and happy operators, until the extra packs reach a warehouse that did not ask for them. In FMCG the cost is real: material and labour spent on stock nobody ordered, shelf life used up on the shelf and write-offs when it expires. Most overruns are not careless. They come from buffers, long changeovers and the lack of a clear stop signal at the line. Plants that want to see how far their lines run past orders can review order-by-order overrun measured from their own production counts in a short session.
Stop the Line at the Order, Not a Few Percent After It
iFactory AI compares live counts with the order, warns before the target is reached and triggers the changeover on time.
Why Lines Run Past the Order
Overruns have causes, and most of them are reasonable on the day. Each cause below has a matching fix.
What an Extra Thousand Packs Costs
The cost of overproduction is spread across several lines of the budget, which is why it is rarely added up. The bars show an illustrative split for one extra thousand packs.
Find Out How Far Past the Order Your Lines Really Run
Share a quarter of orders and production counts. iFactory AI will show overrun by line, product and shift, with the cost of the extra output.
Planned Against Actual, Order by Order
Schedule adherence is easy to say and hard to see without data. The columns show eight illustrative orders, with planned quantity and actual output side by side.
A Changeover Trigger That Warns Before the Target
A crew cannot stop at the right pack if the line gives no warning. Four states, tied to the live count, prepare the changeover in time.
Pull Signals and Allowed Overrun
A pull signal tells the line what is wanted, and when, instead of letting it guess. Allowed overrun then depends on the product, as the table shows, with illustrative policy values. Planners can see overrun limits applied by product on their own orders in a short walkthrough.
| Product Type | Allowed Overrun | Reason |
|---|---|---|
| Short shelf life | 0 to 1% | Write-off risk is high |
| Promotional packs | 0% | Pack has no later use |
| Stable ambient range | 1 to 3% | Extra stock can be sold later |
| Private label | By contract | Tolerance agreed with the customer |
A Composite Scenario: Overrun Cut by Half
A plant added live counts against orders and a changeover warning. The figures below are illustrative.
Where iFactory AI Fits
Orders, counters and the line schedule live in separate systems. iFactory AI joins them, so overrun is seen as it happens.
Live Count Against Order
Output is tracked against the ordered quantity in real time.
Changeover Warnings
Crews get a heads-up before the target and a prepared handover.
Overrun Reporting
Overrun and shortfall are reported by order, line, product and shift.
Cost of Extra Output
Each overrun is costed in material, time and write-off risk.
Expert Review: Preventing Overproduction Without Missing Orders
Preventing overproduction must not create shortages. This review sets out how experienced planners judge the trade-off.
Frequently Asked Questions
Is some overproduction always necessary?
A small allowance is often sensible, to cover yield loss and quality rejects. The aim is to set it deliberately, from measured yield, and not to add it by habit. The right level differs by product. Our team can estimate your allowance from a sample of orders, so buffers are based on evidence.
Will stopping at the order risk short shipments?
Not if yield is understood. Orders should be released with an allowance for expected loss, and the live count should track good packs only. Where a short shipment would be costly, planners can set a small tolerance. Visibility of stock and demand reduces the temptation to run long as a precaution.
How does this relate to changeover time?
Closely. When changeovers are long, supervisors run extra to avoid them, so shortening changeovers reduces overproduction pressure. Starting preparation before the target is reached also saves time. See a changeover warning flow in a short walkthrough using your own line states.
Can the line stop itself at the order quantity?
That depends on your controls and policy. Many plants begin with warnings and a clear display, and some link the count to a line stop or an automatic recipe change later. Any link to line control should be agreed with your controls engineers and operations leaders, with a clear manual override.
How is the benefit measured?
By tracking average overrun, the share of orders outside limits and write-offs linked to overproduction, before and after. All three come from order and production records. Ask for a sample overrun report that planning and finance can both use.
