Study On Scope Management Of Information System Project

The scope management is the foundation of IS project management. The presented literatures have shown that the lack of proper project definition and project scope management is the main cause of project failure. Scope management of information technology application project includes as follows: project selection and target identification, definition of requirements, defining the scope of the project (product range and scope of work),ork breakdown structures, scope recognition and change management. The major theories, tools and methods is applied in the PMBOK, requirements engineering, UP/RUP, agile process knowledge systems, scope management knowledge and so on, there are more dispersed, and with the upper delinked strategy, and with lower separated from work, failure to form the organic whole one from strategy to specific work. To cover the gap between scope management and the up and lower level, make strategy, scope management and specific work to form a whole scope management framework. This dissertation integrates the scope management topics in Requirement Engineering in Software Engineering, using by PMBOK, UP/RUP and Agile Process, and build the "four horizontal and five vertical" ISPSM framework model. Based on the studying of IT life cycle, the main characteristics of the development model of IS project, scope management, requirements engineering, UP/RUP and agile methods.The four horizontal of ISPSM is consist of four level such as strategy, business Objectives, user requirements and task/work package, and building a hierarchy structure from far and near layers of refinement from the strategy to specific task/work package, and the upper lever is the result of lower, the lower is the expansion and decomposition of upper and supporting on the upper level. The five vertical factors include Define, Modeling, Audits, Tacking and Controls, it contain the works of IS project and control system.As an application, our presented model with the ISPSM Framework is applied in the implementation of the comprehensive operation analysis system of Making& Packing, and achieved good results.Our conclusions show the ISPSM model is proposed in this paper could apply to complex information systems scope management needs to make up for the inadequacy of existing scope management is decentralized.
