* Error Proofing Participant Guide ? Copyright 2005 – Federal-Mogul Corporation Draft 06/02/2005 Page * Federal-Mogul Lean Enterprise Errors are Inevitable? Many mistakes in production are overlooked because we accept mistakes as part of human nature. Looking at errors as being inevitable allows error or defects to be accepted as part of the production process. Errors can be Eliminated! The underlying belief of a Lean environment is that errors can be eliminated by implementing Error Proofing and using Poka-Yoke techniques. The primary cause of deficient performance is insufficient performance feedback and lack of performance standards. Errors can pass through a system undetected if inspections are done inadequately. * Error Proofing Participant Guide ?

Nous devons casser cette évolution. Nous nous sommes donnés un objectif, qui n’est pas dans les budgets, de passer en dessous de 3?% en 2006. Aujourd’hui, je regarde toutes les demandes d’investissement dans le détail pour être certain que nous allons casser cette tendance. Par rapport à la concurrence, nous dépensons à 3,8?%, soit beaucoup plus que tous nos concurrents. C’est tout à fait inacceptable. * How to apply PY in design 如何做设计防错？ L1 L2 L1 L1 * Examples of Poka-Yokes 防错案例 If can’t re-design, how to do PY? 如果不能重新设计怎么做防错？ How to apply PY in process 如何做过程防错？ Process poka yoke: manage the ris过程防错：管理防错 1 Poka Yoke detects the defect 防错装置发现缺陷 Validate poka yoke at each start of shift/在每一班次开始时验证防错装置 Reaction rules in case of failure/一旦防错不起作用，应用反应规则 Beware of sophisticated devices/小心精密设备 No back-up mode for S/R poka yoke/对于安全/法律特性防错装置没有备份模式 ! 2 Stops the process 停止过程 3 Warns 警告 How do I know whether the part is OK? 我如何知道零件是否合格？ What should I do with NOK parts? 对不合格产品我应该如何处理？ Should I scrap or rework th
