信息系统全生命周期管理是对信息系统所涉及的资产,从系统规划开始,以信息系统为主线,实现项目立项管理、前期设计、设备(软件)选型、采购、安装、调试管理和应用开发等,一直到交付运行后的运行监控、维护保养、移动、封存直至废止的整个生命周期的管理。在信息系统中,引入全生命周期成本管理的理念,在安全稳定运行的基础上,寻求信息系统生命周期内的总体费用最优,从而达到信息系统成本/效益最大化的效果。
Information system life cycle management is the information system of the assets involved, starting from the system planning, information systems as the main line to achieve project management, pre-design, equipment (software) selection, procurement, installation, commissioning management and application development And so on, until after the delivery of the operational monitoring, maintenance, movement, storage until the abolition of the entire life cycle management. In the information system, the concept of total life cycle cost management is introduced to seek the best overall cost in information system life cycle based on the safe and stable operation so as to achieve the effect of maximizing the cost / benefit of information system.
