The problem definition tree is the minimum exit criteria to go from Diamond 5a to 5b. 如果經過初始研究，變差的產生原因還沒有確定，就需要產品工程的支持。問題定義樹是從 5a5b的基本方法。QualityEngineering質量工程5aProblem Solving Toolbox 問題解決工具箱Project title: Poor adjustment of RR door panel 805830Leader: Pedro Aranda AlfaroSponsor:Juan Carlos LiceaArea: VAETCoach: Leonardo Ch225。vez salcedoInitial date: oct042023Final date: oct292023Problem description:This month it was reported by the shipping lot in USA a problem of quality existed in the 805/830 vehicles. The problem is the poor adjustment in RR door panel.Projects statement:Find and improve the Red X that produce the poor adjustment in the RR door panel for the model 805/830 in Silao Assembly plant.Strategy:We initiated this project using the model to model strategy, because there was a good contrast and good leverage based on multivari see pag 6.Measurement system:As measurement system a Force gage was used.This measurement system passed the isoplot with DR=, DM= lbs, and DP= lbs (see page 4)Clue generation:Stage 1 shows that the Red X doesn’t live in the process. The stage 2 shows that the Red X lives in the door panel. The pair parison shows that the door molding is the part with the best contrast.Statistical confirmation:Once we detected the Red X candidate, I decided to do a B vs C six pack trial, in order to confirm the door molding is the influence to make the customer satisfaction. The six pack passed with 95% of confidence and end count of 6.Irreversible corrective action:To modified the flange mm in length to keep a better position and avoid that the door panel take out of position.Improvements:Reduce warranty cost to repair the door panel caused by poor fit (loose) and eliminate the condition in 100% in vehicles 805/830 models. The amount of money from jul 01 to jul 02 was 11, USD.Lessons learned:We learned that is necessary looking other alternatives using other strategy when is not possible invest money but always focus to guarantee the customer enthusiasm, therefore this project is an example of this.Executive Summary 執(zhí)行總結項目題目 ：右后門板調整不好 (805/830車型 )。領導 ； Pedro Adranda Alfaro發(fā)起人 ： Juan Carlos Licea區(qū)域 ： VAET教練 ： Leonardo Chavez salcedo起使日 ： 2023年 10月 4日截止日 ： 2023年 10月 29日問題描述 ： 本月收到報告，在美國有關于門飾板的質量問題，右后門飾板調整不好。 (805/830型 )項目綜述 ： 針對 Lilao裝配廠 805/830車型的右后門飾板，發(fā)現并解決其配合不好的問題。策略 ： 我們起初應用車型對車型策略，因為多車之間有很好的對比度和平衡關系。 (見見第 6頁 )測量系統(tǒng) ：用測力計作為測量系統(tǒng)。這種測量系統(tǒng)通過等量圖。 (DR=, M=, P= 4頁 線索產生 ： 階段 1表明紅 X不在過程中。階段 2表明紅 X產生在門飾板處。成對比較表明門型是成對比較點。統(tǒng)計確認 ：一旦我們查到了候選的紅 X， 我們決定做 B vs C六組數據比較，這是為了確認門型影響客戶滿意度。用 6對數據進行比較具有 95%的可信度和最大累加值為 6.不可撤銷的糾正措施 ：為使門邊緣加長 。改進措施 ：減少保修費用來修復由于配合不好產生的門飾板問題，并且 100%消除 803/805車型的缺陷。學到的經驗 ： 我們學到了 當投資不會太多的情況下，用其它策略以尋求可選擇的方法解決問題。但始終要關注顧客熱忱。此項目便是一個這樣的例子。Project Definition Tree/項目定義樹Problem characterization問題描述Warranty condition/保修條件The problem is presented only in the rear door問題只是在后側車門出現BASED: DISTRIBUTON LOT CAMPAINGCURRENT: 100 % door panel 805830 models loose目前狀態(tài)： 805/830型車門飾板 100%松動。GOAL: eliminate 100% the poor fit.目標： 100%消除不良的配合Project statement項目綜述Need energy to release the trim door panel需要用力才能卸下門飾板Customer is calling the problem in both sides客戶現在對兩側都在抱怨Effort to release (lbs)/釋放力 (磅 )Frequency頻率 CURRENT現有 DESIRED希望Solution tree項目解決樹TARGET: Eliminate condition 100%目標： 100%消除現有問題PASSED ISOPLOT DR= SEE PAG 4通過等量圖驗證 DR= 參見第 4頁PASSED STAGE 1 SO THE RED X DOESN’T
