信息系统开发的递进模型研究

Studying of the Evolution Model in Information Systems Development

随着信息系统的发展和应用的深入 ,许多学者从不同的角度对信息系统进行研究 ,信息系统的开发是一重要的研究领域 ,对其开发模型的研究已取得了巨大的进展 ,早期的生命周期模型为信息系统的建模奠定了重要的基础 ,后来发展了结构化模型、瀑布模型、螺旋模型、原型化模型、旋进原则等 ,对信息系统的开发产生了重要的作用。本文根据多年的开发经验和一些文献案例 ,提出了信息系统开发的递进模型 ,该模型 (1)强调用户、开发人员和第三方监理人员之间的关系 ;(2 )强调了用户的参与贯穿于信息系统开发的始终 ;(3)通过开发过程、目标和管理 控制与监理三部分的特征描述 。

Development of information systems is an important studying domain,and research of development models have made great effort. The early life cycle model is a base of information system development. From then on,the structured life cycle model,Waterfall model,Spiral model ,Prototyping,SPIPRO Principles et al are proposed to impulse the development of information system modeling.Based on cases of information system development in literatures and our developing experiences,we propose the evolution model of information system development. This model:(1) emphasizes the relationship among customer,developer and auditor; (2) highlight the customer's involvement in the full development process; (3) features the generational nature of the process,the object and the management/control and audit,which facilitates the evolution of systems.
