Terms from A-Z

The term Lean derives from the improvement methodologies developed, refined and applied to the specific business needs of Toyota. These methodologies are commonly referred to as the Toyota Production System (TPS) or the Toyota Business System. In its entirety, TPS has many techniques of implementation, methodologies for deployment and tools for tactical analysis. To be successful, all of the above must be supported by a management philosophy that creates a culture of continuous improvement. This combination of understanding, maturity and tactical skill, when developed and deployed properly, enables performance improvements through the identification and elimination of “waste”.
