基于质量工程方法的信息系统改进

Information System Improvement Based on Quality Engineering Method

以质量功能展开(QFD)为导向,获取客户对信息系统的关键性能要求,并以失效模式及后果分析(FMEA)为指导,在信息系统实施期间对可能产生的失效模式及潜在风险进行预测.通过结合两模型,实现客户利益同时最大程度提升企业效益.随后,比较了QFD与FMEA的相似性和互补性,构建了基于QFD与FMEA的质量管理联合模型,分析了联合模型在信息系统质量提升方面的具体应用流程,并以办公自动化(OA)信息系统为例进行了实例验证.基于QFD与FMEA的结合应用,为信息系统质量的提升提供了一种可参考的方法,该方法具有可操作性与可行性.

Quality function deployment （QFD） was employed to get customers key function requirements on the information system, and with the help of failure mode and effect analysis （FMEA）, potential failure modes and possible risk severity prediction on the process of product life stages in the early development of information systems could be found. The methods met the interests of customers and it maximized the enterprise efficiency at the same time. The similarity and complementarity between QFD and FMEA were analyzed by building a joint quality management model based on QFD and FMEA. A case study was made as well on the OA information system on the basis of the application of the joint model, which improved the information system, and the method was proved feasible and practible.
