1、,1,7 Diamond Process七颗钻石流程,Developed by: GMTG-Arlington L. ONeal / C. Kessler Aug 2000,Revised: 8 Aug 2000,2,What is the 7 Diamond Process?七颗钻石的流程是什么？,The 7 Diamond Process is one of many tools that can be used in the problem solving process. 七颗钻石流程是可以用来解决质量问题的工具之一。 This tool is used to investigate

2、discrepancies discovered by the following: 它可以用来调查以下方面发现的差异 Global Customer Audit System (GCAS) 全球顾客评审 Yard Walk Audits 生产线上巡检 Verification Stations 检验工位,3,Purpose of the 7 Diamond Process 7颗钻石流程的目的,The 7 Diamond Process is a structured way of assessing our manufacturing process to determine whether

3、 of not it has failed to meet the quality standard demanded by our customers. 7颗钻石流程是一个构建好的评价我们的制造流程是否满足了顾客所要求的质量标准的一个方法,4,7 Diamond Process 流程,Responsibility 责任,QET PST (Lead) 5b,SMT RGM (Lead) 6,Statistical Engineering (Red X Strategies) 统计工程(红-X方法) 7,Will Process Change Resolve? 工艺更改能解决问题吗,Produc

5、r enthusiasm limit is 18 lbs.this is enough to keep the door panel in position at low cost.一旦确定Red X 为门外板装饰件，我们决定改变策略， 从车型到车型变到卡车到卡车，因为门外板装饰件对Cadillac车型来说是唯一的。换句话说，同样的门板装在805/830 车型上却产生了差异，原因是一些门板从门上拽出需要20磅的力，二另一些只需要小于10磅的力; 顾客的要求是18磅，这已经足够保证门板以较低的成本固定到相应的位置。,BOB,WOW,BIG CONTACT AREA,SMALL CONTACT A

6、REA,大间隙BIGGAP,小间隙SMALLGAP,门边缘DOOR FLANGE,门边缘 DOOR FLANGE,The main characteristic that cause difference between the door panels 805/830 model is the poor contact of the flange on the door due that there are panels that present some deformation on the top edge and cause the poor contact.引起805/830 车型门外

7、板差异的主要特征饰门边缘连接不良，导致门板上边缘变形,BOB vs WOW door panel最好、最坏门外板对比,DOOR FLANGE CURRENT USED,DOOR FLANGE PROPOSED,This picture shows that if we change the door flange 1.5 mm lenght we guarantee that all door panels require almost 18 lbs to pull out it position because the contact area will be bigger against

8、door flange current,DOOR FLANGE CURRENT USED,DOOR FLANGE PROPOSED,这张图片表明如果我们把门边缘加长1.5mm，我们确保开门力会增大18磅，原因是接触面积比当前增大了。,当前使用的门边缘,推存使用的门边缘,B = Vehicles with new flange longer than 8.5 mm. C = Vehicles with current flange smaller than 7.9 mm. Req: confidence = 95%,Passed B vs C with 95% of confidence tha

9、t the new flange length 1.5 mm is the Red X with complete separation and end count of 6.,B vs C Six pack,B=门边缘比当前长8.5mm的汽车 C=门边缘比当前小7.9mm的汽车 可信度为95%,检测数据通过了B vs C ，95%可以相信加长1.5mm的门边缘是完全独立的红X，并且累计数是6。,CUSTOMER SATISFACTION LIMIT,CURRENT PROCESS,BREAK POINT,Effort (lbs),Green Y Run Chart,RL RL RL RL R
