    7. Requirements Elicitation Techniques

    7.需求捕获技术

    Among the most common techniques used for requirements elicitation, are:

    · Interviews

    · Group meetings

    · Questionnaires

    在需求捕获中最常见的技术就是：

    · 用户访谈

    · 小组会议

    · 问卷表

    Each of these techniques works better in a particular kind of scenario and due care needs to be taken in deciding which one to use when. In most of the projects, none of these three techniques will alone suffice as the de-facto standard for RE. Instead the team will need to use a suitable combination of all three to target different subsets the from stakeholders’ community.

    上述的各种技术在特定场合都能很好发挥作用，应该好好的考虑在何时使用哪项技术。在大多数项目中，捕获需求不可能只采用某个技术。实际情况中，项目组会根据不同的风险承担人团体采用不同的方法。
