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(jié)項(xiàng)目題目 ：右后門(mén)板調(diào)整不好 (805/830車(chē)型 )。領(lǐng)導(dǎo) ； 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(wèn)題描述 ： 本月收到報(bào)告，在美國(guó)有關(guān)于門(mén)飾板的質(zhì)量問(wèn)題，右后門(mén)飾板調(diào)整不好。 (805/830型 )項(xiàng)目綜述 ： 針對(duì) Lilao裝配廠 805/830車(chē)型的右后門(mén)飾板，發(fā)現(xiàn)并解決其配合不好的問(wèn)題。策略 ： 我們起初應(yīng)用車(chē)型對(duì)車(chē)型策略，因?yàn)槎嘬?chē)之間有很好的對(duì)比度和平衡關(guān)系。 (見(jiàn)見(jiàn)第 6頁(yè) )測(cè)量系統(tǒng) ：用測(cè)力計(jì)作為測(cè)量系統(tǒng)。這種測(cè)量系統(tǒng)通過(guò)等量圖。 (DR=, M=, P= 4頁(yè) 線索產(chǎn)生 ： 階段 1表明紅 X不在過(guò)程中。階段 2表明紅 X產(chǎn)生在門(mén)飾板處。成對(duì)比較表明門(mén)型是成對(duì)比較點(diǎn)。統(tǒng)計(jì)確認(rèn) ：一旦我們查到了候選的紅 X， 我們決定做 B vs C六組數(shù)據(jù)比較，這是為了確認(rèn)門(mén)型影響客戶滿意度。用 6對(duì)數(shù)據(jù)進(jìn)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(mén)邊緣加長(zhǎng) 。改進(jìn)措施 ：減少保修費(fèi)用來(lái)修復(fù)由于配合不好產(chǎn)生的門(mén)飾板問(wèn)題，并且 100%消除 803/805車(chē)型的缺陷。學(xué)到的經(jīng)驗(yàn) ： 我們學(xué)到了 當(dāng)投資不會(huì)太多的情況下，用其它策略以尋求可選擇的方法解決問(wèn)題。但始終要關(guān)注顧客熱忱。此項(xiàng)目便是一個(gè)這樣的例子。Project Definition Tree/項(xiàng)目定義樹(shù)Problem characterization問(wèn)題描述Warranty condition/保修條件The problem is presented only in the rear door問(wèn)題只是在后側(cè)車(chē)門(mén)出現(xiàn)BASED: DISTRIBUTON LOT CAMPAINGCURRENT: 100 % door panel 805830 models loose目前狀態(tài)： 805/830型車(chē)門(mén)飾板 100%松動(dòng)。GOAL: eliminate 100% the poor fit.目標(biāo)： 100%消除不良的配合Project statement項(xiàng)目綜述Need energy to release the trim door panel需要用力才能卸下門(mén)飾板Customer is calling the problem in both sides客戶現(xiàn)在對(duì)兩側(cè)都在抱怨Effort to release (lbs)/釋放力 (磅 )Frequency頻率 CURRENT現(xiàn)有 DESIRED希望Solution tree項(xiàng)目解決樹(shù)TARGET: Eliminate condition 100%目標(biāo)： 100%消除現(xiàn)有問(wèn)題PASSED ISOPLOT DR= SEE PAG 4通過(guò)等量圖驗(yàn)證 DR= 參見(jiàn)第 4頁(yè)P(yáng)ASSED STAGE 1 SO THE RED X DOESN’T
