A visual representation illustrating the interconnected elements of a lean manufacturing methodology developed by Toyota Motor Corporation. It graphically depicts the flow of materials and information, highlighting key principles such as Just-in-Time (JIT) delivery, autonomation (jidoka), and continuous improvement (kaizen). These charts often include symbols and annotations representing workstations, inventory buffers, and control mechanisms that collectively aim to eliminate waste and maximize efficiency across the production process.
The schematic serves as a powerful communication tool and a blueprint for implementing lean practices within an organization. Its benefits include enhanced process understanding, improved problem-solving capabilities, and a framework for identifying areas for optimization. Its origins trace back to the post-World War II era, evolving from a need to overcome resource constraints and meet growing consumer demand, ultimately revolutionizing manufacturing practices worldwide.
