Most expensive problems do not start expensive. Watch the first signals.
Most expensive problems in OEM electronics do not start expensive. They start as a small, manageable issue — a requirement read two ways, a fix that did not hold. What makes them expensive is rarely the problem itself. It is how late it is found.

The cost of a change is not fixed. It grows with every stage the problem survives. A correction made while the design is still open is small. The same correction found in validation, or in the field, is not. The five signals below show a problem moving from cheap to expensive — and APQP is what moves the moment you find it earlier. Whether these signals are found early often depends on your supplier — and whether your supplier really uses APQP.
Five signals a small issue is about to get expensive
Each team describes the requirement differently
When teams explain it in different ways, the problem usually appears later.
The same issue keeps returning
If an issue returns after a fix, the real cause was probably missed.
Testing has already started
Once testing begins, a small change affects tests, reports and timing.
More teams are now involved
When engineering, quality, production and purchasing all join, the cost grows.
The fix now touches timing
Once it touches schedules, deliveries or customers, it is no longer only technical.
The question is not only what the problem is. It is when you find it.
The cost of finding it late: design, validation, field
Found while the design is open. A small correction.
Found in testing. Rework, retesting, schedule pressure.
Found after shipment. Warranty, urgent action, lost trust.
An electronics design and manufacturing partner for OEMs
KELD is an electronics design and manufacturing partner for OEMs in HVAC, ventilation, motors, pumps and refrigeration. We apply APQP from the early stages of a project, so problems are found early — when they are still cheap to fix. See how we work with OEM teams.
APQP moves these signals earlier.
The earlier a problem is found, the cheaper it is to fix. That is the work APQP brings forward.
