6、iled as possible 明确过程或方案的目的, 越详细越好F.M.E.A.How does it operate?如何运做以达到目标的？Step 2 Describe in detail how to achieve the goal step by step, like process flow, new product concept, new plan, etc. 详细描述是如何一步一步达到目的的， 例如新的流程，新的产品概念，计划等。F.M.E.A.Step 3What can go wrong with respect to the goal?针对目标，会发生什么问题？Ev

7、ery people raise the questions what can go wrong by brainstorming during meeting 针对目的，在会议上用头脑 风暴法，指出可能 出错的地方F.M.E.A.Step 4What are the weakest points (risk evaluation)?哪个是最弱点？Risk风险 = Probability概率 * Severity严重性Probability and severity can be scored 1,2,3 or L,M,H概率和严重性可以用 1，2，3 或高中低打分F.M.E.A.Step 5

8、What are the action plan for highest risk? 针对高风险，制定行动计划Preventive action if probability is highCorrective action if severity is highThen PDCA1, 概率大的问题，制定预防性措施2, 严重的问题，制定纠正性措施然后进入PDCA循环F.M.E.A.Flow Chart应用流程Concept designRisk minimum?Next phaseYesNoFMEAActionF.M.E.A.Key successful point成功要点(1)： Where

In every phase of a project.任何可能出错的地方，项目的任何阶段 Attitude during FMEA 工作态度Be open-minded for criticism!针对批评，有则改之，无则嘉勉F.M.E.A.Key successful point成功要点(2)： Meeting team会议成员 relevant people(supplier, customer or process owner), expert and non-expert, max. 10 people相关人员（供应商，客户和主人），专家或非专家，最多10人F.M.E.A.Key successful point成功要点(3)： Good preparation做好准备Give participants all information before meeting, put drawing, samples, instruction on the table or on the front wall, using injector and
