在当今许多大型跨国组织机构中,信息系统对投资的回报就像它所支持的用户一样负有责任,糟糕的是,当我们没有直接的评价方式时,证明信息系统价值就更显得非常困难。对于那些选择接收信息系统的人们,信息系统的任务是为最终用户提供服务;在不增加成本(最好是降低成本)的条件下,保证关键性任务应用软件的可用性和安全性,并在未来的发展过程中,不需要按比例增加人力投入。应用软件的管理需要贯穿整个生命周期,从开发、测试、首次公布、产品更新、修补,一直到新版本和新版本的发布等等。
In many large multinational organizations today, information systems pay for the investment as much as the users it supports, and worse, the value of the information system is more difficult to prove when we do not have a direct evaluation. For those who choose to receive information systems, the mission of the information system is to serve the end user; to ensure the availability and security of mission-critical applications at no additional cost, preferably cost reduction, and in the future In the course of development, there is no need to increase manpower input proportionally. Application software management needs throughout the life cycle, from development, testing, first release, product updates, patching, until the new version and the release of the new version and so on.
