Basic Stability
A condition in which the 4Ms (manpower, machines, materials and methods) are sufficiently reliable for flow and pull improvements to work.
Examples
- 01Before introducing kanban on the machining line, the lean team checks basic stability: machine availability is only 72 % and material arrives late twice a week.
- 02Leaders walk the line daily to verify basic stability, looking at unplanned stops, missing operators, material shortages and unclear methods, the 4Ms.
- 03Once availability is above 90 % and the main material problems are fixed, basic stability is good enough to start one-piece flow, and the gains are held through standard work.
