u Waste only adds time and cost, no value. 浪费只增加时间 和成本，不增加价值。
u Waste is the reason that product flow stops and is the cause for non competitiveness. 生产流动的停止是造成浪 费的原因，浪费是缺乏竞争性的根源。
Lean is a philosophy where waste is identified continuously and eliminated passionately. Waste is any activity (or inactivity) that consumes resources for which the customer is not willing to pay.

4. 帮助你看到不仅仅是单一的过程，将物流
Value Stream Mapping 价值流图
What we mean by Value Stream Mapping is simple:
我们所说的价值流图是很简单的：
1. Follow a product’s production path from beginning to end (supplier to customer) . 产品的生产路线从开始到结束（供应商到客户）
价值流程图是用铅笔和白纸作为工具，帮助你去识别和理解在整个产品
价值流中的物流和信息流然后利用精益工具，消除浪费。
1. 让所有与目标价值流有关的人对当前以及 未来的状态形成共同看法。
2. 为便于交流，提供可视化图，提供共同语 言。
3. 使每个人都能看到浪费的现象，从而将大 家的注意力都集中到改进生产上来。

What Types waste 浪费分类
• 1型浪费： 指的是一系列虽然不对外部顾客创造价值，可能对内部客 户创造价值，主要是因为目前的工艺及技 术水平或工艺需 要，还不能立即彻底消除的耗费资源的活动。 1型浪费同样需要去减少和消除。
• 2型浪费： 指的是可以通过改善，立即可以消除的浪费形态。浪费广 泛存在于现场之中，主要以7种典型的浪费形式存在，是我 们需要群策群力，去观察、发现并立即消除的对象。
