Analysis of Requirement Engineering Processes, Tools/Techniques and Methodologies

TLDR: The study reviews the prominent processes, tools and technologies used in the requirement gathering phase and highlights the importance of security requirements as though they are part of the non- functional requirement, yet are naturally considered fundamental to secure software development.

Abstract: Requirement engineering is an integral part of the software development lifecycle since the basis for developing successful software depends on comprehending its requirements in the first place. Requirement engineering involves a number of processes for gathering requirements in accordance with the needs and demands of users and stakeholders of the software product. In this paper, we have reviewed the prominent processes, tools and technologies used in the requirement gathering phase. The study is useful to perceive the current state of the affairs pertaining to the requirement engineering research and to understand the strengths and limitations of the existing requirement engineering techniques. The study also summarizes the best practices and how to use a blend of the requirement engineering techniques as an effective methodology to successfully conduct the requirement engineering task. The study also highlights the importance of security requirements as though they are part of the non- functional requirement, yet are naturally considered fundamental to secure software development.
