问答题

试题一A公司是国内一家大型系统集成企业,已建立基于SJ/T 11234、SJ/T 11235的涵盖公司所有部门和人员的质量管理体系。在公司建立质量管理体系之初,质量部要求各业务部门都参加体系建设,编写程序文件和作业指导,但这些部门都说忙,难以抽出人力。质量部便借鉴了其他公司的体系文件,对其简单修改后形成了A公司的质量管理体系文件。质量管理体系运行一年后,公司承担了一个大型软件集成项目。公司领导对此项目非常重视,任命高级项目经理陈工管理此项目,并强调一定要保质保量完成。同时,公司要求销售部、采购部、质量部各抽派一个人参与该项目,配合项目组开展工作。根据公司的质量管理体系要求,项目的每个里程碑节点都要召开评审会,主要开发文档(包括需求规格说明书、总体设计和详细设计等)都需要通过评审。事实上,在以往的项目中,这些评审会都是项目组内部讨论,讨论出结果后让相关部门负责人签字,质量部只要看到有签字的评审记录就不干预项目的实施。由于本项目关系重大,各部门都怕出了问题而承担责任,因此所有部门都参加了该项目的评审会。几个评审会开完,项目组成员开始抱怨。说以前的项目评审都是我们自己讨论,其他部门根本没人仔细看。可是现在这个项目,各个部门都有人参与,评审会上每个人都提意见,并且意见经常不一致,没有人负责最后拍板;对于有些技术文件的评审,评审人员明明不懂还提出很多问题,还要费很大力气给他们解释。在以往的项目中,虽然公司的程序文件中规定评审没通过就不能进入下一环节,但如果进度要求紧张的话,一般也不管什么流程了,抢进度要紧。但是在这个项目中,设计方案经过几次讨论都没有结果。项目经理陈工为了保证进度,向采购部提出提前采购设备,采购部以设计方案没定稿为理由拒绝处理。无奈陈工找了好几次公司领导,最终领导拍板可以提前采购。项目就这样在不断的争执过程中进行,每次争执不下时陈工就去找公司领导。如此多次争执后,陈工发现质量管理体系文件中规定那么多评审纯粹浪费时间,希望修改。按照计划,现在项目应该进行到测试阶段,但实际上项目的详细设计还未通过评审。

请简要叙述A公司的质量管理体系在建立和运行中存在的主要问题。
