CORE DEFINITION

Just-in-Time (JIT): Produce only what is needed, when it is needed, eliminating inventory waste. Jidoka (Autonomation): Stop immediately when an abnormality occurs, making problems visible. Kaizen (Continuous Improvement): Incremental optimization involving all employees. Scaffold role: Eliminate waste, pursue flow. By eliminating the seven wastes (overproduction, waiting, transportation, over-processing, inventory, motion, defects), achieve an efficient and smooth production system. It has expanded from manufacturing to services, healthcare, software development, and other fields. Related variants: Toyota Circle, Toyota-style improvement.

TPS has two pillars: Just-in-Time (JIT, producing only what is needed, when it is needed, eliminating inventory waste) and Jidoka (Autonomation, stopping when an abnormality occurs, making problems visible), supplemented by Kaizen (Continuous Improvement). The mechanism is to achieve high flow, high quality, and low cost by eliminating the seven wastes and making problems "visible."

MINIMUM ACTION

In progress 0/5

Practice this model in one real situation:

Map the value stream to identify waste
Use kanban to implement pull-based JIT
Set up andon/Jidoka to stop the line on abnormalities
Engage all employees in small-step improvements
Transfer across industries (service/healthcare/software).
