简单图表法是质量统计管理中常用的方法。这种方法不仅简便易用,

</DIV><DIV style="mso-element: frame; mso-element-frame-width: 449.8pt; mso-element-wrap: auto; mso-element-anchor-horizontal: column; mso-element-left: 100.45pt; mso-element-top: 56.95pt; mso-height-rule: exactly">

所需工具易于筹措,而且可以直观地反映引起质量变化的原因。简单

图表法主要有:检查表,排列图,因果图,树图,系统图,关联图,

流程图,矩阵图,矢线图,直方图,分层图,散布图,控制图。

检查表也称为核对表或调查表,通常用于产品的相关问题调查时收集

</DIV><DIV style="mso-element: frame; mso-element-frame-width: 449.8pt; mso-element-wrap: auto; mso-element-anchor-horizontal: column; mso-element-left: 100.45pt; mso-element-top: 148.7pt; mso-height-rule: exactly">

和整理质量原因原始数据。检查表一般由产品项和调查原因项组成。

</DIV><DIV style="mso-element: frame; mso-element-frame-width: 435.65pt; mso-element-wrap: auto; mso-element-anchor-horizontal: column; mso-element-left: 100.45pt; mso-element-top: 170.8pt; mso-height-rule: exactly">

有时用于调查产品出现质量问题的原因,有时用来调查产品成本原

因,有时也可以用来总结调查产品的成功原因。例如,关于生产线的

</DIV><DIV style="mso-element: frame; mso-element-frame-width: 449.8pt; mso-element-wrap: auto; mso-element-anchor-horizontal: column; mso-element-left: 100.45pt; mso-element-top: 215.0pt; mso-height-rule: exactly">

改造项目中,总结生产线的优越性时,就需要将原生产线生产同样产
