* PDCA 改进模式 C-Check 检查 A-Action 纠正活动 D-Do 执行 P-Plan 计划 Continuous Improvement PDCA是一个持续的品质改善的螺旋上升循环 * 优质企业 客戶满意 P D C A P D C A P D C A PDCA 持续改进 PDCA不是一个平面环，它是阶梯式上升的，这个循环走完一遍应该就已经解决一部分问题，取得一部分成果，到了循环的下一个周期，在范围上就应该产生了变化，所以说它不是一个平面环。 * Ford-8D Practice Follow this template! * 使用 Ford 8D 的时机 Consequences identified　因果关系的鉴别 Cause unknown　原因不明时用8D来找原因 Resources for problem solution recurrence prevention management-approved 解决问题的资源和防止再发生措施的批准 Single-person capacity for problem-solving exceeded 　不是一个人能解决的，需要通过脑力激荡和团队合作来解决 Symptoms defined　异常状况已经出现，并很明显 Symptom quantified with measurement　异常状况可量化 * Ford-8D Workflow Describe the Problem D1: 主题选定及小组成立 D2: 问题描述及原因确认 D3: 展开暂时防堵措施 D4: 定义及验证真因 D5: 列出, 选定及验证永久对策 D6: 执行永久对策及效果确认 D7: 预防再发及标准化 D8: 恭贺团队及未来方向 Prevent Recurrence Implement Permanent Corrective Action Recognize Team Individual Contributions Y N Establish a Team Develop Interim Containment Action Define Verify Root Cause Choose Verify Permanent Corrective Actions * D1: Team Building Establish a team with people: 与此project 或工作相关的人 有cross function的人一起参与 有相关的knowledge experience 定期（每周/每月）review进度 * D2: Problem Description What is wrong with what? How can the problem be quantified? What? When? Where? How much? Cause Effect? Something changed / never been successful? * D3: Development of ICA ICA = Interim Containment Action (暂时防堵措施) Quick fixes Temporary detective actions Isolation from harmful effects. Short-term action before PCA are taken. PCA = Permanent Corrective Action * D4: Definition Verification of Root Cause Identify “real problem”- 5 why Test each possible cause. Systematic use of resources. Ideality (What it is in best way) NO? YES? * Root Cause Identification - Sampling Problem: Bipolar transistor gain in BiCMOS process out-of-spec high at e-test (WAT). 在WAT测试中发现BiCMOS工艺中的双极晶体管增益高出规 范的要求 Why#1 Why was the bipolar transistor gain too high?
