【正文】 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 ：右后門板調(diào)整不好 (805/830車型 )。問(wèn)題定義樹(shù)是從 5a5b的基本方法。5aIs Engineering support required?是否需要工程的支持13168。3168。1CorrectProcess?正確的工藝流程Rel.
