【正文】 TQ改進(jìn)程序 23 ? Implement Alarm Reaction Plan if Limit Exceeded 如果超過警戒限，執(zhí)行反應(yīng)計劃 ? Reaction Plan:反應(yīng)計劃 Alarm Limit Exceeded? 超出警戒限 Contain 抑制 Investigate 調(diào)查 Implement Containment Plan Until Problem Fixed 執(zhí)行抑制計劃直到問題解決 Yes Containment Plan 生產(chǎn)抑制計劃 FTQ Improvement Process FTQ改進(jìn)程序 24 ? Record Data 記錄數(shù)據(jù) ? Data must be recorded and plotted over time: 要按時記錄數(shù)據(jù)并繪制數(shù)據(jù)圖 ? At the cell level, the number of pieces rejected shall be recorded by defect category at a defined frequency. This data must be used to react to abnormal process conditions (process monitoring) 每個作業(yè)區(qū)都必須用不良記錄表以一定頻次來記錄不良品數(shù)目．?dāng)?shù)據(jù)必須用來對異常程序作出反應(yīng)．（程序監(jiān)測） ? Since the area of opportunity varies from sample to sample, the reject count must be converted into a rate (FTQ PPM) prior to charting 因為樣品與樣品的 ? Each area should have a performance tracking board that would reflect the manufacturing FTQ information by shift FTQ Improvement Process FTQ改進(jìn)程序 25 ? Analyze Data ? 分析數(shù)據(jù) ?The basic quality tools are: ?基本的品質(zhì)工具 ? Flow Charting流程圖 ? Check Sheets報帳單 ? Pareto柏拉圖 ? Cause and Effect因果圖 ? Run Chart ? Histogram柱狀圖 ? Scatter Diagram散布圖 ? Control Chart控制圖 FTQ Improvement Process FTQ改進(jìn)程序 26 Initiate Structured Problem Solving 開始程式化問題解決 Understand Defects and Decide the Order of Priority: 了解不良并確定優(yōu)先順序 Assign problems to CrossFunctional Group: 向獨立功能性小組提交問題 Select and Plan the Improvement: 1 Right Information 2 Right Cause 3 Right Timing 選擇并計劃改進(jìn) :1 正確的信息 2 正確的原因 3 正確的時間 Fix the Biggest Problems First: 先解決最大的問題 1 2 A B C D Problems 1 2 1 2 Responsible Team Works Problems 負(fù)責(zé)小組指出問題 DEFECT 1. 2. 3. 4 3 2 3 2 2 1 1 1 1 First Time Quality Process 一次下線合格率程序 27 ?Analyze Data ?分析數(shù)據(jù) Problem Identification 問題識別 Problem Analysis 分析問題 Flowchart 流程圖 Brainstorming 頭腦風(fēng)暴 Pareto Chart 柏拉圖 Cause amp。工作標(biāo)準(zhǔn)就象一個處方：不同的工作方法和內(nèi)容將得出不同的結(jié)果 FTQ Improvement Process 29 ? Implement and Evaluate執(zhí)行和評價 ? Once the Corrective Action has been implemented, the data must be evaluated for trends or shifts一旦矯正行動被執(zhí)行，就使用數(shù)據(jù)移動趨勢來評估 ? Did the problem stay “killed?” Can you turn the problem on and ? off? If so, change alarm limits and update the documentation ? This is one of the reasons it is so important to collect data over time ? Without data there is no way to evaluate the impact of the corrective action on the process如果沒有數(shù)據(jù)，就沒有辦法評估實施在過程上矯正行動的效果 ? If no significant reduction in FTQ PPM is observed, then it is possible the cause was misidentified 如果 FTQ PPM沒有重大減少，說明可能識別的原因是錯誤的 FTQ Improvement Process 30 ?Institutionalize Lessons Learned and Look Across ?Lessons Learned must be incorporated into all existing documentation. Then Look Across to ensure implementation in all applicable processes, products. ? DFMEA’s設(shè)計 FMEA ? Process Flow Diagram過程流程圖 ? PFMEA’s 過程 FMEA ? Process Control Plans過程控制計劃 ? Process Routings 過程路線 ? Operating Instructions操作指導(dǎo)書 ? Employee Instructions員工指導(dǎo)書 ? Product Drawings 產(chǎn)品圖 ? Tool Drawings 工具圖 ? Total Productive Maintenance (.) TPM ? Boundary Samples 邊界樣件 FTQ Improvement Process 31 Closing Comments FTQ Improvement Process ?Implement Improvement ?Work the Action Plan ?Update plan as required ?Document improvements
