A use case map as a visual approach to reduce the degree of inconsistency

Extracting excellent requirements is one of the challenges that face the software developers. The characteristics of excellent requirements are concise, complete, necessary, unambiguous and consistent. Within a context where there is a lack of common understanding of what must be traced especially in generating consistency requirements, a number of methods have been proposed to software requirements consistency and traceability. Many of these dealing with requirements consistency using inconsistency rules given by software customer which may inadequate. This paper provides a guideline approach based on a visual technique that helps to reduce the degree of inconsistency which may appear by redundancy of tasks in more than one requirements.
