Wastage & Scrap Tracking That Actually Reduces It
Short answer: A scrap and wastage tracking system captures every production loss at the point it occurs — by job, by work centre, and by reason — so that management has the data to identify which machines, products, or operators drive the most waste, and can act on it.
Why "We Know We Have Wastage" Is Not Enough
Most manufacturers have a rough sense of their scrap rate. They see it in the monthly material variance or when a physical stocktake reveals less material than the system shows. What they do not have is the breakdown: which product line, which shift, which stage of production, and which reason code.
Without that breakdown, reducing wastage is guesswork. You can tell operators to be more careful, but you cannot tell them specifically what to be careful about or measure whether the instruction made any difference.
What Gets Recorded at the Point of Waste
A scrap recording screen on the factory floor captures:
- Job or production order — so the cost is allocated correctly, not written off to a general "scrap" account
- Work centre or machine — identifies whether one machine generates disproportionate scrap
- Quantity and unit of measure — in the same UOM as the material being consumed
- Reason code — operator error, material defect, machine malfunction, specification change, rework rejection
- Disposition — binned, returned to supplier, rework, or sold as off-grade
The reason code is the most important field. Without it, you have a number. With it, you have a cause.
Scrap Cost Allocation
Scrap that is not allocated to a job distorts job costing. If 3 kg of material is scrapped during Job #6102 but recorded as a general write-off, Job #6102 shows a better margin than it actually achieved. The next time you price a similar job, you quote based on a cost that was artificially low.
When scrap is allocated to the job at the point of recording, the job cost is accurate. A job costing system that reads from real scrap records produces margins you can rely on for future quoting.
The Trend View: Where Reduction Happens
Recording scrap is the prerequisite. Reducing it requires trend analysis. The questions that drive reduction are:
| Question | What it reveals |
|---|---|
| Which product has the highest scrap rate over 90 days? | Whether a BOM yield factor needs correction |
| Which work centre generates the most rework rejections? | A machine calibration or maintenance issue |
| Which reason code is growing month on month? | A systemic problem rather than random variation |
| Does shift A have a different scrap rate than shift B? | A training, supervision, or handover issue |
A dashboard that surfaces these comparisons turns raw scrap data into an improvement programme. Our inventory and warehouse system includes the stock-side tracking; dashboards for the trend analysis can be added as a separate layer.
Operator Usability at the Point of Recording
Jacob Ng designs floor-facing interfaces around simplicity. A wastage recording screen needs to be completable in under 30 seconds by an operator who may be recording it while managing a running machine. That means:
- Large tap targets, not small text fields
- Pre-populated job number from the active production order
- Reason codes as selectable buttons, not a free-text field
- Immediate confirmation feedback so the operator knows the entry was saved
A form that takes two minutes to complete will be skipped under production pressure. A form that takes 20 seconds will be used.
Integration With Stock and Accounts
Each scrap transaction reduces the WIP stock balance for the affected material and posts the cost to the relevant job. At job close, the total scrap cost flows into AutoCount alongside other production costs, without a separate journal entry.
This means your accounts team sees accurate material costs without manually tracking down scrap records at month-end.

FAQ
Can we track both process scrap (expected yield loss) and abnormal scrap separately?
Yes. The system distinguishes between standard yield loss (encoded in the BOM as expected) and abnormal scrap (recorded as a transaction with a reason). Only abnormal scrap appears as a variance.
What if operators on the floor do not have access to a device for recording?
Shared workstation terminals at each work centre are a practical alternative to personal devices. The recording screen is designed to function on any touchscreen or keyboard-only device.
How does scrap tracking help with supplier quality issues?
When "material defect" is selected as a reason code and tied to a specific raw material batch, the system accumulates a defect rate by supplier and batch number. That data supports supplier quality discussions and return-to-supplier claims.
