A clean showroom and a binder of certificates tell you a factory can pass an audit. They do not tell you how it behaves at 2 a.m. on a Friday when a line is behind. That is what we are actually there to learn.
Before we travel
The desk work comes first: a valid business licence, the scope of any ISO 9001 or ISO 14001 certificate (and whether it actually covers the process you need), customer references, and capacity that matches the volumes you are discussing. A certificate whose scope excludes your process is a flag, not a credential.
On the floor
This is where an audit earns its keep. We look for evidence that quality is a system, not a person:
Process control. Are there documented work instructions at each station? Is there statistical process control where it matters, a real first-article inspection, and in-process checks — or is inspection only at the end, where defects are most expensive?
Traceability. Can they tell you which lot and date code went into a given unit, and pull the records? When something goes wrong in the field, traceability is the difference between a contained recall and a guess.
Calibration and ESD. Calibration stickers in date on test equipment; grounded benches, wrist straps and ionisers actually in use, not hanging unused on a hook.
Material handling. How moisture-sensitive parts are stored and baked, how rejects are quarantined, how rework is tracked.
The questions that reveal behaviour
We ask to see the last few nonconformance reports and what corrective action followed. We ask how engineering changes are controlled and communicated. We ask what happens when a shipment is late — whether they ship anyway and inspect later. The answers, and how readily they come, say more than any score.
The quiet red flags
A factory that cannot produce records on request, that routes every question through one person, that has no quarantine area, or that is visibly running far above its sustainable capacity is telling you something. We would rather hear it before the purchase order than after the first field return.
Need a factory audited before you commit?
We audit and qualify suppliers in person, against your standards, and give you the photos and findings — not a rubber stamp.
