拜访的工厂多了之后也练就了“火眼金睛”，一目了然知道工厂在作业指导书这个细小的环节上仅仅只是走走形式，还是落实到实处，正所谓魔鬼都在细节里。比如作业指导书的适用范围是广泛而包罗万象的还是具体到每款产品型号的？其框架结构，排版方式？最后的修订日期是2年之内的，还是从来就没发生过？有确认，有审批吗？有被人翻阅过吗？是横挂还是竖挂示于员工？详细程度如何？
If one person has visited too many factories, then he/she will have good intuition , knowing only at a glance whether the factory take the work instruction as a form or in real implementation.  Like the old saying, devils are in details. For example, are the work instruction applied for a wide product ranges or each product model specifically? Does It has a good structure and layout? Is it revised in the last 2 years, or never? Are there any confirmation of examination and approval? Has it ever been read by others? Is it hanged horizontally or vertically to present to the staff for easy reading? Are details included?
