Revisiting requirement analysis techniques and challenges

Abstract

Requirement analysis is one of the major activities of requirement engineering (RE) process, which is an iterative process of discovering and analysing feasible features to produce a contracted set of complete and consistent requirements. Revolution and developing business environments demand well-defined and complete requirements for successful software development. In spite of various trend-setting requirement analysis methods/tools/framework/techniques, it has been observed that few techniques are useful with certain systems, but at the same time, few of them may not be useful for others. Accordingly, identification/selection of correct requirement analysis (RA) techniques becomes more important before moving further towards other activity in RE. Accordingly, an attempt has been made in this paper to illustrate the requirement analysis process, various techniques and their related challenges. It is expected that the same would facilitate the concerned stakeholders to understand and choose the most suitable RA technique to be used in their project/s.
