Key takeaways
OEE tracks three losses: availability, performance, and quality. But there is a fourth loss it was never designed to see, and in filling and packing operations it can dwarf the others. It is called giveaway, and it hides in plain sight because the product it wastes still looks perfect.
Any operation that fills to a weight or count has a target and a legal or label minimum. To avoid ever going underweight, plants aim above the target. The distance between what you actually put in the pack and what you needed to is giveaway: material handed to the customer for nothing.
A little is unavoidable. The problem is that the noisier your filling process, the higher you have to aim to stay safe, and the more you give away on every single unit.
OEE quality rate is a simple ratio: good units divided by total units. An overfilled pack is a good unit. It passes inspection, ships, and satisfies the customer. So from OEE's point of view, nothing was lost. The line can run at a flattering quality rate while quietly bleeding raw material on every pack. This is exactly why giveaway is the quality loss OEE forgets, and why it needs its own measure. It sits alongside the classic losses in the six big losses framework as the one most plants never quantify.
The cost is deceptively large because it compounds. A small average overfill, multiplied by every unit, every line, every shift, every day, turns into a serious material and margin number over a year. Unlike scrap, there is no dramatic event to trigger action, which is precisely why it survives for years. The mechanism, not any single number, is the point: constant, invisible, and fully avoidable margin loss.
You cannot manage what you do not measure, and a pass or fail checkweigher is not enough. To see giveaway you need the fill-weight distribution, not just the pass rate:
The counterintuitive part: you do not cut giveaway by lowering the setpoint, you cut it by reducing variation. A wide, noisy fill distribution forces a high safety margin. Tighten the distribution and you can safely move the average down toward target without risking underweight packs. That means stabilising the filling process, using checkweigher feedback to correct drift, and treating fill variation as a process problem, not an inspection one. Fabrico helps by making this loss visible alongside OEE so it stops being invisible. See how a connected OEE platform surfaces losses OEE alone misses, especially in FMCG and CPG lines, or book a demo.
No. Scrap is product you throw away; giveaway is good product you overfill and ship for free. Scrap shows up in OEE quality rate; giveaway does not.
Because OEE quality rate only asks whether a unit is good or bad. An overfilled unit is good, so the loss is invisible to the metric.
Any filling or portioning operation: food, beverage, cosmetics, personal care, chemicals. Anywhere a target weight meets a legal minimum.
Reduce fill-weight variation first. A tighter distribution lets you lower the average toward target safely; lowering the setpoint on a noisy process just creates underweight packs.
Yes. Treat it as a fourth loss next to availability, performance, and quality, especially on high-volume filling lines where small overfills compound fast.
