- Mejora continua, Eficiencia, Justo a tiempo (JIT), Fabricación ajustada, Producción ajustada, Eficacia global de los equipos (OEE), Mejora de los procesos, Eficacia de la producción, Intercambio de troqueles en un minuto (SMED)
Objetivo:
Cómo se utiliza:
- Involves analyzing the changeover process, separating internal setup operations (done when machine is stopped) from external setup operations (done while machine is running), converting internal to external steps, and streamlining all remaining operations.
Pros
- Increases machine uptime and production flexibility, reduces manufacturing lot sizes and inventory, improves responsiveness to customer demand, lowers production costs.
Cons
- Requires significant initial effort for analysis and implementation, may require investment in tooling or equipment modifications, needs strong operator training and discipline, benefits may be less significant if changeovers are already infrequent or fast.

Lo mejor para:
- Manufacturing environments with frequent equipment changeovers, aiming to improve efficiency, reduce lead times, and enable smaller batch production.
