Define alarm limits and reaction plan 確定警戒限及反應計劃 ? Alarm limits must be based on current process reject data or available data from Machine qualification runs, Run at Rate, historical data, etc. 警戒必須基于現(xiàn)工序的不良數(shù)據(jù)或是從機器在一定功率下運行產(chǎn)生的歷史數(shù)據(jù)，等． ? Need to collect data long enough to ensure you understand the types and quantities of defects that fall out from your current process. Limits for mon cause (chronic) rejects may be statistically calculated 必須經(jīng)過足夠長時間的數(shù)據(jù)收集，我們才能確定從現(xiàn)運行程序中漏掉的不良品的種類和數(shù)量．一些共同原因產(chǎn)生的不良也可通過這些統(tǒng)計被找出． ? Understand process and expected defects (what types and quantities of defects)了解程序和預估不良（不良品的種類和數(shù)量） ? Determine the process normal range of variation by charting the reject data over time通過對不良數(shù)據(jù)制表認知，確定程序的正常變化幅度 20 FTQ Improvement Process FTQ改進程序 ? Define alarm limits and reaction plan 確定警戒限及反應計劃 ? Limits for special cause (non chronic) rejects must be set at one piece 突發(fā)原因產(chǎn)生的不良顯示必須在一產(chǎn)生時就做出調(diào)整 ? Limits must be municated to operators so they can react 限定還必須與操作員交流清楚以便他們能及時反應 ? If alarm limits are exceeded, there must be a documented reaction plan which includes containment of product and process corrections. 如果警戒限被超，要有書面的反應計劃包括生產(chǎn)抑制以及程序更正 ? Employees may find clever ways to identify abnormal process state as the process matures 隨著程序的成熟，職工也會發(fā)現(xiàn)識別異常的巧妙方法 ? The immediate action taken is the most important step in containing the problem until it has been eliminated and verified 遏制問題的最重要的步驟是快速采取行動直到問題被消除并核實． 21 Quality Alarm Limit: 品質(zhì)警戒限 Example: Rejected Parts Counter 例：不合格品的計數(shù) The counter is flipped for each defect. The color will change from green to yellow to red. 在每個不良品上要附上這種卡片．顏色有綠黃紅三種． Yellow indicates action required and red will stop the process. 黃色表示要采取行動，而紅色表示停止工序 Small white tags are placed with each defective part to identify the specific defect. 每個不良品上會有一個白色小標簽注明不良原因 22 ? Identify and count rejected parts 識別及清點不良品 ? Operators must have sufficient tools and skills in order to identify product discrepancies 操作員必須有足夠的工具及技能來識別產(chǎn)品缺陷 ? It is remended that rejected parts be removed from the cell station at a defined frequency so they may be counted and categorized by defect or rework code 不良品應定期從工作區(qū)移開，以便進行計數(shù)并不良品號碼登記 ? Tools to enhance the operator’s ability to identify product discrepancies include: 用來增強操作員識別產(chǎn)品差異的工具包括： ? Boundary Samples 對比樣品 ? Illustrations 圖表 ? Photographs 照片 ? Gages 計量器 ? Tools for counting rejected parts include: 清點不良品的工具有： ? Parts Counters 計數(shù)器 ? Tally Sheets 計數(shù)表 ? Sized Containers 定容器 FTQ Improvement Process F
