Quintessence of Traditional and Agile Requirement Engineering

Abstract

Requirement gathering for software development project is the most crucial stage and thus requirement engineering (RE) occupies the chief position in the software development. Countless techniques concerning the RE processes exist to make sure the requirements are coherent, compact and complete in all respects. In this way different aspects of RE are dissected and detailed upon. A comparison of RE in Agile and RE in Waterfall is expatiated and on the basis of the literature survey the overall Agile RE process is accumulated. Agile being a technique produces high quality software in relatively less time as compared to the conventional waterfall methodology. The paramount objective of this study is to take lessons from RE that Agile method may consider, if quality being the cardinal concern. The study is patterned on the survey of the previous research reported in the coexisting literature and the practices which are being pursued in the area.

Challenges in Migration from Waterfall to Agile Environments

“…Finally, the involvement of stakeholders throughout the process and the correct identification of user needs are a permanent challenge for the success of agile methodologies. Priorities of user stories implementation are setup for all iterations, which offer opportunities for getting desirable results and customer satisfaction [36].…”

Revisiting Requirement Engineering Techniques: Managerial Perspective

“…Requirements Management is a novel term, which has improved in status in later years, and the area"s comparatively enormous form of literature has made it gradually easy to collect significant information [7]. It is performed throughout RE process and includes all activities such as version control, changes control and requirements tracing [8]. The essential task of requirements management is assuring the traceability of the requirements both onwards and backwards and from the initial requirements gathering activities through to system development and maintenance.…”
