老QC七大手法讲解（101页）

Quality Control 七大手法=品管七大手法

1950年代由日本首先提倡，並於1980年代發揚光大至全世界

一沒有足夠而正確的工具來得知事件的真相跟“瞎子摸象” 無異。在錯誤方向下，越努力的人·所造成的損失越大。戴明博士(W.EdwardsDeming)稱之為「努力挖掘自已的墳墓」

憑經驗去決定問题點·不易掌握重點·應利用統計方法來解析所得的數據或圖表·藉以取得重點;QC七大手法是目前最簡單、常用的統計手法·時時刻刻在生活中出現·分別如下:

1.查檢表(Checklist):收集、整理實料

2.直方圖(Histogram):展示資料的分佈情況

3.散佈圖(Scatter Diagram):展示變數之間的線性關像

4.柏拉圖(Pareto Diagram):確定主導因素

5.管制圖(ControlChart):識別波動的來源

6.特性要因圖(Characteristic Diagram):尋找引發結果的原因7.層別法(Stratification):從不同角度層面發現問题
