4 Issues in Requirements Elicitation
4、需求捕获的问题
Eliciting requirements need not be like pulling teeth … but sometimes it is. The problem is lack of preparation by the software engineer and lack of interest by the organization or person requesting the work. One would think that the customer would be very interested， since the software to be built solves a problem that the customer has. But often， the customer expects the developer to "know" and has little interest in spending time doing "computer stuff." A mistake， no doubt， but reality none the less. One can use the Requirements Elicitation Success Measurement checklist to identify where your project stands as far as the success of the requirements elicitation is concerned. For this checklist， the more questions that elicit a negative response， the higher the risk that the requirements elicitation will fail.
需求捕获不象是拔牙…但也比较类似。常见的问题是，软件工程师缺乏准备，同时需要该产品的组织或个人缺乏兴趣。一般大家都会认为客户会对产品很感兴趣，因为该产品会解决客户面临的问题。但通常客户希望开发人员已经知道相关知识或不愿意耗费时间为软件产品提供基础材料。无疑，这些观点是错误的 ，但是客观存在的。可以使用需求捕获列表来验证你的项目在需求捕获方面进展如何。在这个列表中，越多问题的答案是否定的，那么需求捕获失败的可能性就越高。
Requirements engineering consists of activities like requirements elicitation， specification and validation.
