Introduction
Most buyers ask this question after a shipment that disappointed them. The instinct is to switch suppliers. Sometimes that is the right answer. More often, the current supplier can produce better quality — if the buyer changes how the relationship is structured.
This article covers what actually improves quality from a supplier already producing for you.
1. Tighten The Specification
Vague specifications produce inconsistent quality. Review the specification document from the buyer’s side and identify every place a factory could interpret it in more than one way.
Add:
- Specific tolerances instead of “approximate”
- Photos of both acceptable and unacceptable variants
- Named material grades instead of category terms
- Defect examples with severity classification
A tighter specification does not require the factory to produce better; it just removes the interpretations that produce inconsistency.
2. Add A Quality Level The Factory Sees Publicly
Suppliers behave differently when they know defect rates are being measured. Share your inspection results with the factory after each shipment — total inspected, defects found, categorisation, and rate compared to previous shipments.
The transparency itself changes behaviour, even before any commercial consequence.
3. Pay For Better Production Conditions
Sometimes the factory can produce better quality but is not choosing to on your order. Reasons:
- Your order is small compared to their large customers, and gets junior workers
- Your unit price forces material substitutions the factory would not otherwise make
- Your lead time is tight enough that in-process inspection was skipped
Discuss these with the supplier honestly. Sometimes an incremental payment for prioritised production changes the output meaningfully.
4. Adjust The Payment Structure
Payment terms drive supplier behaviour. If the entire balance is paid before pre-shipment inspection, the supplier has already been paid — quality problems become the buyer’s problem.
Move payment terms so that balance is released after PSI, not before. Suppliers who refuse this are telling you something.
5. Consolidate Instead Of Diversifying
Buyers often assume that splitting orders across two suppliers reduces risk. Sometimes it does. But consolidating volume with one strong supplier — and using that volume as leverage — usually produces better quality than dividing attention across two weaker relationships.
6. Consider The Supplier Simply Cannot Deliver
Some quality problems are structural. The factory does not have the equipment, workforce, or process control to produce your product consistently.
In that case, the answer is a different supplier — but only after the changes above have been tried. Otherwise the new supplier will produce the same problems.
FAQ
How long does it take for quality improvements to show up? Typically 2–3 production cycles after the changes are implemented. The first cycle is the factory adjusting; the second cycle is stable output.
Should I switch suppliers after one bad shipment? Usually not. One bad shipment is data. Two bad shipments after implementing changes is a decision.
Can a sourcing partner improve quality on my existing suppliers? Yes. Hansen works with existing supplier relationships as well as new ones — often the improvement comes from process changes rather than supplier changes.
Improve The Quality On Your Next Production Run
Better quality from the same supplier is often achievable — if the process changes. If you would like Hansen to work with your existing supplier on this, start a project.
