Field notes

What people said after the tape came off the floor.

SOP Recovery Lab made us throw out three binders. The remaining pages are the ones operators actually touch. I still wish we had started with the tool crib instead of packing.

Attended Constraint Walk for Owners. Short, blunt, and we left knowing which press to stop feeding first. Would have liked a second afternoon on costing the leap jobs.

Review left on the studio card, food-pack converting

Mei from Fengyuan. After Handover Discipline Studio the night crew stopped rebuilding the afternoon’s kit list from memory. The morning still argues about labels.

Client in die-cast housings: the Diagnostic Walk was enough to cancel a planned extra inspector. The wait was not skill; it was a tray with no steward.

Case: export windows at a fastener house

A 42-person plant near Wurih kept missing Friday sailings even when machines were free. Value Stream Clinic mapped one family: zinc-plated screws for a Japanese buyer. The grid showed inspection overnight as a second, unofficial shift.

They named a QC steward on evenings, cut the tray pile, and stopped launching a second colour while the first sat unsigned. On-time sailings for that family rose over the next two months. Other families were left alone on purpose.

Case: a family shop that would not write names

A father-and-sons machining cell treated every wait as “we all own it.” Constraint Walk for Owners forced three named squares: fixture cabinet, first-piece sign-off, and the dock list.

They did not adopt the full Line Reset. The father still overrides the dock list on Tuesdays. The sons keep the fixture log. That mixed result is the honest end of the study.
