1、,1,7 Diamond Process七顆鉆石流程,2,What is the 7 Diamond Process?七顆鉆石的流程是什么？,The 7 Diamond Process is one of many tools that can be used in the problem solving process. 七顆鉆石流程是可以用來解決質(zhì)量問題的工具之一。 This tool is used to investigate discrepancies discovered by the following: 它可以用來調(diào)查以下方面發(fā)現(xiàn)的差異 Global Customer Audi

3、鉆石流程是一個構(gòu)建好的評價我們的制造流程是否滿足了顧客所要求的質(zhì)量標準的一個方法,4,7 Diamond Process 流程,Responsibility 責任,QET PST (Lead) 5b,SMT RGM (Lead) 6,Statistical Engineering (Red X Strategies) 統(tǒng)計工程(紅-X方法) 7,Will Process Change Resolve? 工藝更改能解決問題嗎,Product Change Required? 產(chǎn)品更改需要嗎？,Hardy Perennial or Extremely Complex Problem 非常復雜的問題

5、t low cost.一旦確定Red X 為門外板裝飾件，我們決定改變策略， 從車型到車型變到卡車到卡車，因為門外板裝飾件對Cadillac車型來說是唯一的。換句話說，同樣的門板裝在805/830 車型上卻產(chǎn)生了差異，原因是一些門板從門上拽出需要20磅的力，二另一些只需要小于10磅的力; 顧客的要求是18磅，這已經(jīng)足夠保證門板以較低的成本固定到相應的位置。,BOB,WOW,BIG CONTACT AREA,SMALL CONTACT AREA,大間隙BIGGAP,小間隙SMALLGAP,門邊緣DOOR FLANGE,門邊緣 DOOR FLANGE,The main characteristic

6、 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 車型門外板差異的主要特征飾門邊緣連接不良，導致門板上邊緣變形,BOB vs WOW door panel最好、最壞門外板對比,DOOR FLANGE CURRENT U

7、SED,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 door flange current,DOOR FLANGE CURRENT USED,DOOR FLANGE PROPOSED,這張圖片表明如果我們把門邊緣

8、加長1.5mm，我們確保開門力會增大18磅，原因是接觸面積比當前增大了。,當前使用的門邊緣,推存使用的門邊緣,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 that the new flange length 1.5 mm is the Red X with complete separation and end cou

9、nt of 6.,B vs C Six pack,B=門邊緣比當前長8.5mm的汽車 C=門邊緣比當前小7.9mm的汽車 可信度為95%,檢測數(shù)據(jù)通過了B vs C ，95%可以相信加長1.5mm的門邊緣是完全獨立的紅X，并且累計數(shù)是6。,CUSTOMER SATISFACTION LIMIT,CURRENT PROCESS,BREAK POINT,Effort (lbs),Green Y Run Chart,RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL RL
