Basic stability: the foundation for continuous improvement
Basic stability is a crucial concept within Lean and refers to the presence of the necessary capacity, reliability and flexibility of the 4 M's: People, Machinery, Material and Methods. Without a stable base, it is impossible to sustainably implement and sustain improvements.
A process with basic stability satisfies the following characteristics:
Basic stability is the prerequisite for effective Just-in-Time (JIT) production. It is the first step in a cycle of improvement that often proceeds as follows:
1. Create basic stability.
2. Realizing flow (current).
3. Tuning to branch time.
4. Implement a pull system.
4. Leveling (heijunka).
This cycle is repeated until the process is fully optimized.
