Screen-Based Prototyping Toolset: a Tool for Requirements Engineering in End-User Computing.

Software Engineering has been recognized as one of the most challenging issues in computer science during the last three decades. Furthermore, requirements engineering as a significant process in a software development process plays a crucial role. Research shows that the cause of most of the projects' failure is the requirements engineering process. End-User Computing, on the other hand, which involves end-users directly and actively in the software development life cycle, suffers from the same problems. In addition, this area of software engineering is faced with some risks and problems arising from special characteristics of End- User Computing. In this regard, several method, techniques, and tools are developed to solve the problems. The prototyping method among other requirements engineering methods is more effective due to its tasks' coverage and its ability to involve end-users in the software development process. Therefore, the Screen-Based prototyping method can be considered as a useful solution. A toolset to support various features of the Screen-Based Prototyping is developed and discussed in this paper. The evaluation of the toolset was accomplished using some case studies. Both qualitative and quantitative analyses of the results showed that the toolset positively affects the process of software development and stakeholders of the project are satisfied with the features provided by the toolset.
