WHAT IS THE 7 DIAMOND PROCESS 什么是7颗钻石流程
The 7 diamond process is one of many tools that can be used in the problem solving process. 7颗钻石流程是很多问题解决工具中的一种. This blue card is the tool used to initiate the investigation of discrepancies discovered by the following: 蓝卡是用来开始调查下面单位发现的问题的工具: •Global customer audit system(GCAS) •全球客户评审系统 •Yard walk audits •工作区域巡检 •Verification stations •检查工位 •Other •其他

can any of these cause the problem? 这些能够引起问题吗?
工艺流程 •Is the parts routing current? •零件的路线是否是当前的? •Are the correct part numbers identified on the material racks? •物料架上标识的零部件号码正确吗? •Are parts stocked in correct location on the rack? •零件在料架上的正确位置吗? •Are all pull cards available? •是否所有的拉动卡可得到? •Has a paa been issued changing part usage? •是否有paa发布更改零件的使用? •Has the paa expired? •Paa过期了? •Is error proofing needed? •防错是否需要? •Is existing error proofing device working correctly? •现有的防错设备是否工作正常?
•7颗钻石的前4颗(也就是蓝卡)为生产提供了一种结构化的方法 ,它可以评估工艺 过程，决定是否原设计能够生产出符合客户要求的高质量产品。

7 diamond process stages 7颗钻石流程阶段
Stages 1&2 of the process are used to determine if the production organization is running the assembly process to design intent. 阶段1和2 用来确定生产组织是否正在按照设计意图去实施装配工艺。 Stage 1 the initial investigation diamonds 1 through 4 begins at the point where the defect was created. If every thing is found to be “OK” then the investigation would go to stage 2. 阶段1 钻石1到钻石4最初的调查是从缺陷产生的地方开始。如果一切OK，那么调查进入第二阶 段。 Stage 2 is only used when the investigation in stage 1 has determined that the cause of the problem is from an upstream source。Diamonds 1 through 4 are repeated at the suspect work station 阶段2 只有当阶段1已经确定问题的原因在上游时才被用到。钻石1到4在怀疑的工位上反复作。 If the process isnot being managed to design intent, then it must be corrected and validated, prior to asking for engineering assistance. 如果工艺不能符合原设计,那么在寻求工程协助之前, 必须纠正和确认。 Stage 3 engineering involvement occurs when the manufacturing process does meet design intent and the problem still exist. 阶段3 当制造工艺符合原设计并且问题依然存在时, 工程开始介入了。 7

Purpose of the 7 Diamond Process
7颗钻石流程的目的
•The first 4 diamonds(i.e. blue card)of 7 diamond process provides manufacturing with a structured method of assessing the process to determine if the as designed is capable of producing a product that meets the quality standards demanded by our customers.
