Abstract:
Within the requirements engineering domain, requirements elicitation (RE) is one of the most difficult phases. Towards a successful and high-quality software development process, RE often suffers from information challenges such as ambiguity, incompleteness, and inconsistent data. Within this context, this research aims to analyze the contribution of RE combined techniques of both i) the elicitation of functional requirements (FR), and ii) non-functional requirements (NFR) at an Information Systems Higher Education (IS) course. Via a systematic literature review (RSL), 61 articles crawled from the Scopus database that meets the RE search criteria were fully reviewed and finally generated the list of RE. The top three REs (Interview, Prototyping, and Brainstorming) were then used to support the IS course case study with 56 students. Results showed that combined FR and NFR techniques improved the RE completeness and consistency when compared to every single technique isolatedly.
