• 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。
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。 4. 帮助你看到不仅仅是单一的过程，将物流和信息流联系起来 5. 为推进改善提供蓝图。 6. 将精益的概念和技术紧密结合起来

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） Carefully Draw a visual representation of every process in the material and information flow. 过程导向，把物流和信息流和用一种直观可视的方法仔细的表 现出来。 Then ask a set of questions and draw (using Icons) a “Future State” map of how value should flow. 然后问一系列问题，用图标画在指明价值流动的将来价值流图
