Reading a factory in one walk
What a buyer or technologist can reliably judge in a single forty-minute walk — and what they cannot.
A first factory visit is short, and almost everything shown is prepared. The signals that survive preparation are the ones worth reading.
Look at work in progress between operations, the state of the repair area, whether measuring tools at the cutting table are in calibration date, and how the line balances after the bottleneck. Ask an operator what they do when a defect appears — the answer describes the real system.
What a walk cannot tell you: true capacity, delivery reliability, or how the factory behaves in a bad month. Those need order history and a second visit, unannounced if the relationship allows it.
