用于生产参考的检测项目也需要制定标准么?

小弟,刚开始投入质量体系这行(一个月时间),以前从来没有涉及。
负责体系工作的体系专员（我的老师）最近离职了，新的人员还没有到位。
最近公司又在接受客户的审核，真是焦头兰额
我在的公司是玻璃生产企业，客户在审核的时候提出了这样的问题：
7In the QC monitor check list(XUG-PG-42-001-A
A: There is one items"edge width" ,the check frequency is 8time/Shift,but actually record is 4hour/time .A internal memo was shown that the frequency was changed to 4hour/time from 2008.02.25
  Why the frequency was changed so big from 1hr/time to 4hr/time ?
  Why the record form still kept old version after two month the internal memo issued?
B: There are no specs on the check list. I ask for the spec of edge width A,B,C,D . QC don't know the spec and said the spec was at Hot end engineer side . But when we go to the production side, they can not show the spec and explain it's just a reference data .
   No spec, how the QC discover the deviation?
   Why is not QC make alarm for deviation ? What's the function of QC ? Just a recorder ?
   What's meaning of just as reference control ? No reaction limit?   
老师们，对这样的不合格项，我们该怎样着手来改啊？
急！
