Formalization, Testing and Execution of a Use Case Diagram

Abstract. Errors in a requirements model have prolonged detrimental effects on reliability, cost, and safety of a software system. It is very costly to fix these errors in later phases of software development if they cannot be corrected during requirements analysis and design. A Use Case diagram, as a requirements model, plays an important role in giving requirements for a software system. It provides a communication tool between software requirements developers and prospective users to understand what requirements of a software system are. However most descriptions of a use case diagram are written in some informal language, leading to possible misunderstanding between developers and users. In this paper, we propose a new rigorous review technique which can be applied to software requirements models. Using this new technique before a software system is fully designed will help us find some potential errors in a requirements model, resulting in reduced time, labor and expenditure in...
