The difference差异 Note: There may be more than one or no answer. 注：可能不只一个答案也可能没有答案。 D4:DEFINE VERIFY ROOT CAUSES D4:定义和验证根本原因 Develop Change - How Theory逐步展开如何变化的推论: How could this change have created ? 变化能引起怎样的 ？ Operational Definition操作性定义 Or或者 b) In what ways might this CHANGE create @ cause ? 哪些方面可能使变化引起 。 Operational Definition操作性定义 Eg. How could this new operator have create clogging on Charlie? 例子：在Charlie上新操作员怎样引起堵塞？ D4:DEFINE VERIFY ROOT CAUSES D4:定义和验证根本原因 D4:DEFINE VERIFY ROOT CAUSES D4:定义和验证根本原因 “Theory Testing”测试推论 If (Change-how theory) is the cause of ＿ (Operational Definition) of does it explain why only the (Is) is affected, but never the (Is Not)? 如果 （怎样变化的推论）是 （可操作性定义）的原因，那么它可否解释 （是）受影响而 （否）不受影响的原因？ + = Yes Both Is and Is Not explained ＋：“是” 是与否双方的说明 = No Does not explain Is and/or Is Not －：“否” 说明是或否 ? = Need additional information to draw conclusion ？：需要附加说明以定结论。 D4:DEFINE VERIFY ROOT CAUSES D4:定义和验证根本原因 Reminders提示 ☆ Note and check out assumptions记录并检查假设 ☆ In the event you end up with a large number of likely causes: 结果你以很有可能的原因的大量数据结束 －－Re-ch
