Important factors in selecting Requirements Engineering techniques

Requirements Engineering is the most complex part of software engineering process. Several tasks and techniques have been proposed to do RE process, but selecting a suitable set of techniques is still a challenging issue. Researches in selecting RE techniques mostly focus on particular aspects of techniques. However, RE techniques are influenced by various factors from different viewpoints. This paper tries to explore important factors in RE technique selection from different viewpoints, i.e. technique attributes, project and organizational viewpoints, and classify them based on RE tasks.
