THE PROJECTIT-STUDIO/REQUIREMENTS CASE TOOL A Practical Requirements Specification Case Study

Adopting a pragmatic attitude, regarding to the high rate of unsuccess verified among IT projects, and also bearing in mind the importance of the software development process's early stages to overcome this problem, we embraced the goal of creating a CASE tool for requirements specification and validation. Our approach is based on a controlled natural language designated as ProjectIT-RSL and seeks to achieve a higher level of rigor and quality of the produced requirements specifications. The supporting tool, the ProjectIT-Studio/Requirements plugin, belongs to a broader workbench called ProjectIT-Studio, whose main goal is to cover the entire software development life-cycle, providing guidance during the process according to software engineering best practices and methods. This paper presents a small but illustrative requirements specification case study, which emphasizes the current tool's support and its inherent usage advantages during the requirements specification process.
