在需求引出面谈中，分析员发现的模棱两可的地方有助于揭示客户的默契。事实上，模棱两可可能会揭示出需要引出的隐含或难以表达的信息。对模棱两可的看法可能取决于担任分析师的对象，不同的分析师可能会在同一采访中识别不同的模棱两可。基于这一直觉，我们建议调查分析人员在需求激发面试期间显式揭示的歧义和收听面试录音的评审员注释的歧义之间的差异，目的是定义一种面试评审的方法。我们进行了一项探索性研究，其中两名受试者听取了一系列客户分析师的采访。只有26%的案例中，分析员揭示的模棱两可与审查员发现的模棱两可相符。在46%的案例中，评价者发现了模棱两可的地方，而分析员没有发现。基于这些初步发现，我们目前正在对两所大学的学生进行对照实验，随后将与公司进行现实世界的案例研究。本文讨论了目前的结果，并提出了我们的研究计划。
In requirements elicitation interviews, ambiguities identified by analysts can help to disclose the tacit knowledge of customers. Indeed, ambiguities might reveal implicit or hard to express information that needs to be elicited. The perception of ambiguity might depend on the subject who is acting as analyst, and different analysts might identify different ambiguities in the same interview. Based on this intuition, we propose to investigate the difference between ambiguities explicitly revealed by an analyst during a requirements elicitation interview, and ambiguities annotated by a reviewer who listens to the interview recording, with the objective of defining a method for interview review. We performed an exploratory study in which two subjects listened to a set of customer-analyst interviews. Only in 26% of the cases the ambiguities revealed by the analysts matched with the ambiguities found by the reviewers. In 46% of the cases, ambiguities were found by the reviewers, and were not detected by the analysts. Based on these preliminary findings, we are currently performing a controlled experiment with students of two universities, which will be followed by a real-world case study with companies. This paper discusses the current results, together with our research plan.
