需求工程（RE）是系统和软件工程生命周期的一个重要过程。在ISO/IEC 15288:2008，系统和软件工程-系统生命周期过程和ISO/IEC 12207:2008，系统和软件工程-软件生命周期过程中，RE已被确立为ISO/IEC标准生命周期过程。 本技术报告提供了关于RE工具所需功能的指导。它补充了ISO/IEC 14102:2008《信息技术-案例工具评估和选择指南》，该指南详细介绍了一套案例工具的评估标准，但没有提及特定的活动或服务领域。

Requirements engineering (RE) is an essential process of the systems and software engineering life cycles. RE has been established as an ISO/IEC standard life cycle process in both ISO/IEC 15288:2008, Systems and software engineering — System life cycle processes and ISO/IEC 12207:2008, Systems and software engineering — Software life cycle processes. This Technical Report provides guidance on desirable capabilities of RE tools. It supplements ISO/IEC 14102:2008, Information technology — Guideline for the evaluation and selection of CASE tools, which details a set of evaluation criteria for CASE tools without referencing a specific activity or service area.
