摘 要
随着信息需求的不断增长，IT项目的规模越来越庞大，IT项目的功能越来越复杂，信息化的风险也越来越高，金融机构对IT的依赖也越来越重……传统的信息交流方式早已不能满足企业对传递和处理大量信息的需要，信息化的发展过程中已经越来越凸显项目管理在项目实施中的重要性。因此，一套融合国际先进理念、契合企业管理办法的项目管理系统便被提上了企业的信息化建设日程。
本文描述了基于B/S架构的IT项目管理系统的设计与实现的过程，系统的开发采用了业内成熟稳定的J2EE SSH技术架构，设计并实现了企业内部项目的项目立项、人员配备、项目周报、会议纪要、问题管理、项目评审、需求变更、项目调整、项目结项等IT项目建设中的核心管理内容。该项目在开发过程中也严格依据项目管理的要求，从可行性分析到项目需求、设计、编码、测试，历经半年时间，在三名工程师的努力付出下，最终已在企业内部正式投入使用，系统的投产，大幅提升了企业管理层对项目协调的能力，大幅加强了项目经理日常管理的力度，大幅提升了企业项目管理水平的综合实力。该项目的投产，为项目实施的进度管理、质量保障、成本控制提供了有效的信息化的支撑平台。
本次论文重点以项目成本管理为例，通过项目立项及项目周报模块的实现，详细介绍了挣值管理理论在实践中的指导作用。通过项目经理提交项目周报，部门经理对周报实施审批后，系统将自动实现对项目成本偏差及项目进度偏差等挣值管理的相关信息进行实时的采集，该信息为企业领导层掌握项目实施状况提供了成本管理的数据模型，为未来项目管理系统向商业智能分析发展提供了有效的数据支持。
论文最后也讨论了本项目管理系统有待完善的环节和进一步研究的方向，为后续系统的升级改善提供了理论依据。

ABSTRACT
With the increasing demand for information domain, IT project scale size have become more and more bigger, and the project functions are more complicated to before there are many risks because many finance system rely on it heavily. Traditional information exchange method could not meet the enterprise demand to deliver and handle the large amount of information. The importance of Project management during project implementation phase is very prominent in the informatization progress. Hence a project management system which has integrated with international ideas and accorded with enterprise management have been put forward in enterprise informatization construction schedule.
This paper describes the process of design and implementation of IT project management system based on B/S infrastructure. System development have adopted stable J2EE SSH technology frame in the field. Design and achieve the core management contents which related to enterprise internal project establishment, project manpower deployment, project weekly report, meeting minutes, issue management, project approval, demand change, project adjustment and project closing etc during the IT project construction phase. This project will strictly obey with the project management requirement during the design process, starting from feasibility analysis to project demand, design, coding, testing, with the three engineers’ great efforts through half year, this project have been formally put into use in enterprise finally. This system has greatly promoted the project coordination ability for enterprise executives, greatly strengthen the daily management power for project manager, greatly promoted the comprehensive capability for enterprise project management since the system put on line. The system on-line has provided effective informatization supporting platform for progress management, quality ensurance, cost control of project implementation.
This paper have taken project cost management as an emphasized example, describing guideline function of earned value management theory during carry-out phase in details by project establishment and project weekly report model implementation. By the way of project manager to submit the project weekly report,
department manager approve the weekly report, the system will automatically collect the earned value information such as project cost gap and project progress gap from time to time, this information have provided cost management data model for enterprise executives to master the project implementation status, as well as to provide effective data support for future project management system to develop into commerce capacity analysis.
This paper have discussed the improvement part and further research direction for project management system in the end, it has provide theory basis for system improvement in the following.
