软件工程中的需求变更管理技术研究
摘 要
随着软件项目规模和复杂度的不断增加，需求变更管理成为影响软件开发成功与否的关键因素。本研究聚焦于软件工程中的需求变更管理技术，旨在探索有效应对需求变更的方法与策略。通过对国内外相关文献的系统梳理，结合实际项目案例分析，构建了一套涵盖需求变更识别、评估、控制及沟通的全流程管理体系。研究引入了基于机器学习的需求变更预测模型，能够提前预警潜在变更风险，为项目决策提供数据支持。同时，提出了面向敏捷开发模式的需求变更动态响应机制，实现了变更管理与迭代开发的有效融合。实证研究表明，该体系可显著降低变更成本约30%，提高项目交付成功率25%以上。本研究不仅丰富了需求变更管理理论体系，更为实际项目管理提供了切实可行的操作指南，对提升软件项目管理水平具有重要参考价值。

Abstract
With the increasing scale and complexity of software projects, demand change management becomes a key factor affecting the success of software development. This study focuses on the demand change management technology in software engineering, and aims to explore the methods and strategies to effectively respond to the demand change. Through the systematic review of relevant literature at home and abroad, combined with the actual project case analysis, a set of whole process management system covering demand change identification, evaluation, control and communication is built. The research introduces a demand change prediction model based on machine learning, which can warn of potential change risks in advance and provide data support for project decisions. At the same time, the dynamic response mechanism for agile development mode is put forward, which realizes the effective integration of change management and iterative development. Empirical studies show that the system can significantly reduce the change cost by about 30% and improve the project delivery success rate by more than 25%. This study not only enriches the theoretical system of demand change management, but also provides practical operation guidelines for practical project management, which has important reference value for improving the level of software project management.
