Leaning toward Green

摘要

Lean practitioners have long challenged employees to question why a process is performed a particular way and whether it is necessary, and to shift their paradigm to implement a more efficient way to provide customer value.rnTo do so, seasoned lean implementers have developed a keen eye for identifying wastes-at least the conventional types. Often referred to as the seven deadly wastes, these conventional wastes include:rn1. Overproduction ahead of customer demand.rn2. Waiting for the next processing step.rn3. Unnecessary transport of materials.rn4. Overprocessing due to poor tool and product design.rn5. Inventories that are more than the absolute minimum.rn6. Unnecessary movement by employees during the course of their work.rn7. Production of defective parts.
