Use cases are a popular way of specifying functional requirements of computer-based systems. Each use case contains a sequence of steps which are described with a natural language. Use cases, as any other description of functional requirements, must go through a review process to check their quality. The problem is that such reviews are time consuming. Moreover, effectiveness of a review depends on quality of the submitted document - if a document contains many easy-to-detect defects, then reviewers tend to find those simple defects and they feel exempted from working hard to detect difficult defects. To solve the problem it is proposed to augment a requirements management tool with a detector that would find easy-to-detect defects automatically.
