| 摘 要： | 一个信息系统的成功取决于用户需求获取的成效，这种成效受到包括系统分析人员自身认知局限在内的诸多因素的影响。过程提示法从心理学的角度对传统的直接询问法进行改进。这种方法的使用不仅能够克服用户和系统分析人员自身认知局限造成的信息表达和需求获取不充分、不准确等问题，而且比单一的直接询问更能有效的获取用户信息需求。

The Research of Information Requirements Elicitation |
| |
| Abstract: | Information system success is dependent upon the effectiveness of requirements elicitation. Requirements elicitation is subject to numerous challenges, however, including cognitive limitations of analysts. Procedural prompts have made the improvement from the psychology perspective to the traditional interrogatory prompts. It is designed to overcome the cognitive limitations that cause user hard to convey their ideas and analysts to gather inadequate and inaccurate requirements. Providing analysts with procedural prompts to aid their requirements elicitation can result in the acquisition of additional meaningful requirements. In addition, the procedural prompts designed to mitigate cognitive challenges were significantly more effective than simple interrogatory prompts. |
