"pull" production (by means of kanban).

4. JIT/Lean Production
While some believe that Lean Manufacturing is a set of problem solving tools.
In addition, experts in this field believe that philosophy-based Lean Manufacturing strategy is the most effective way to launch and sustain lean activities.

5. Key lean manufacturing principles
Key lean manufacturing principles include:
Perfect first-time quality - quest for zero defects
Waste minimization
Continuous improvement

6. Key lean manufacturing principles
Pull processing: products are pulled from the consumer end, not pushed from the production end.
Flexibility
Building and maintaining a long term relationship with suppliers through collaborative risk sharing, cost sharing and information sharing arrangements.

7. Applications of Lean Manufacturing
