精益生产的历史与含义
精益生产可以实现:
生产时间减少90%
库存减少90%
到达客户手中的缺陷减少50%
废品率降低50%
与工作有关的伤害降低50%
——(来自于丰田的实践数据)
The amount of human effort, time, space, tools, and inventories
can typically be cut in half very quickly, and steady progress can
be maintained from this point onward to cut inputs in half again
within a few years.
—— Lean Thinking by Womack & Jones
