差异是标准作业的敌人
Tenet 7: Variation is the enemy of StandardWork. Eliminate variation at each step of the process. Work towards zerovariation by catching it at the earliest possible step in the process.
准则7：差异是标准作业的敌人。在流程的每一步骤消除差异。尽可能在流程源头找到差异，从而努力达成零差异
a) Whatforms of variation can be created by your process that could impact yourdownstream customer? What do you do to not pass variation downstream?
1. Responsesmay vary.
a) 你的工作流程中会产生什么样的差异影响到下游客户？你要怎样做才能不传递差异到下游？
1．可能有不同的回答
b) Isit better to find variation at the beginning or at the end of a process?
1. It’sbetter to find variation at the beginning of a process. If variation is foundat the end, all the work that’s been done so far needs to get redone.
2. Minimizethe impact of the variation by identifying it as early in the process aspossible.
b) 在流程的前端找到差异更好还是在末端找到差异更好？
1．在流程的最前端找到差异更好。如果差异在末端被发现，所有已完成的工作需要重做
2．通过在流程中尽早找到差异，将差异带来的影响降到最小
c) Whydo we want to attack variation rather than working around it?
1. Standard Work is the fastest, safest andhighest quality way to perform work. Variation is the opposite of this. Themore often we can perform the best method, the faster and the higher qualityproduct we can deliver to the customer.
c) 为什么我们要去解决差异而不是围绕着差异去工作
1．标准作业是最快，最安全，最优质的工作方式。差异是标准作业的对立面。我们越经常地执行这种最佳方法，我们就会越快地交付给客户更优质的产品。
d) Whensources of variation come up on the Gemba Walk, what happens?
1. Simpleproblems with known answers should be addressed immediately (Just Do It).
2. Morecomplex problems are prioritized by senior leadership and will be addressedthrough a structured problem solving methodology (PDCA or Kaizen).
d) 当差异源在现场巡检中被提出，要怎么办呢？
1. 已知答案的简单问题应该被立即解决（立即去做）
2．更复杂的问题由管理者进行优先排序，将通过一个结构化的问题解决方法得以解决（PDCA或改善）
