4 Directions for Future Research
4.1 Directions from our Analysis of RE Research
In this section we derive clusters of activities for future research, while reflecting on
our findings in Sects. 3.1, 3.2 and 3.3.
Our review confirmed the presence of a multiplicity of RE approaches to ES
projects. This is unsurprising, as no one approach is demonstrated to be superior
to another. In addition, we observe that the variety of elicitation and model-
ing approaches brought a variety of empirical studies in which practitioners and
researchers have used these approaches and shared their lessons learnt. We consider
this use of empirical research methods beneficial to the RE community, especially
when the studies are done independently by different researchers and not by the
bias. Moreover, the industrial studies refer to various domains in which ES were
implemented and in a variety of business sectors. This is a positive development as
well, because it opens up opportunities for cross-case analysis of the lessons learnt.
Realizing these research opportunities is a worthwhile endeavor for the future.
