基于CMMI的医院信息系统需求管理

摘要

Requirement management runs throughout the software requirement engineering and it is also an important process area in CMMI (Capability Maturity Model Integration). Contraposing the current HIS (Hospital Information System) characteristics and weak requirement management during the project implementation process, this paper proposed a CMMI-based model and introduced the process-oriented thinking into the requirement management, which was divided into four process models:reviewing requirement, baseline, change control, tracking and adjustment. In practice, the error handling requirement process model and functional requirement process model were established for further improvement of the model.%需求管理贯穿于整个软件需求工程之中，也是软件能力成熟度集成模型（CMMI）中关键的过程域。针对当前医院信息系统（HIS）的特点以及项目实施过程中需求管理方面薄弱的现状，本文以CMMI的需求管理为理论基础，把过程化的思维引入到需求管理中，结合需求管理流程设计了需求管理体系。以此作为构建HIS项目需求管理模式的基础，提出了以需求评审、建立功能基线、需求变更控制、需求跟踪为基本活动内容的HIS需求管理过程模型，并在实际项目中将需求分类为出错性需求和功能性需求，进一步对模型进行了改进与完善。
