The wrong production line

An order failed inspection in bulk this week. The order sheet said “Premium Plus” — the factory’s own top grade. One model ran 1,200 units in four colorways of 300. Between it and its sister model, roughly 1,600 frames came across the bench.

We counted three to four hundred clean.

The defects were not subtle. Rose-gold plating polished through on the push plates — about half the pieces. Logo recesses fogged with excess glue. Plating pins dirty where they should be bright. On one model, the front view did not even match the drawing; the factory had pulled a near-match mold and called it equal. It is not equal. A frame front either follows the drawing or it is a different frame.

Then the question that explains most bad batches: which line built this?

The factory has floors. One floor runs the exacting work under one manager. Another floor runs volume under a different manager. Same gate, same sign, different hands, different math. Our top-grade order had been routed to the volume floor.

A brand seven time zones away sees a factory name and a confirmed order. Inside the building, the difference between two floors was the difference between shipping and not shipping.

We did not pass the batch. The three to four hundred frames that matched the drawing were counted out; the rest stayed behind for rework and remake. And the routing conversation moved up a level, with the floor named.

Twenty years in this cluster taught me to ask “which line” before “which factory”. The factory’s name is on the gate. The work is done on a floor.
