Abstract

[Context and Motivation] Many requirements prioritization approaches have been proposed, however not all of them have been investigated empirically in real-life settings. As a result, our knowledge of their applicability and actual use is incomplete.

[Question/problem] A 2007 systematic review on requirements prioritization mapped out the landscape of proposed prioritization approaches and their prioritization criteria. To understand how this sub-field of requirements engineering has developed since 2007 and what evidence has been accumulated through empirical evaluations, we carried out a literature review that takes as input publications published between 2007 and 2019.

[Principle ideas/results] We evaluated 102 papers that proposed and/or evaluated requirements prioritization methods. Our results show that the newly proposed requirements prioritization methods tend to use as basis fuzzy logic and machine learning algorithms. We also concluded that the Analytical Hierarchy Process is the most accurate and extensively used requirement prioritization method in industry. However, scalability is still its major limitation when requirements are large in number. We have found that machine learning has shown potential to deal with this limitation. Last, we found that experiments were the most used research method to evaluate the various aspects of the proposed prioritization approaches.

[Contribution] This paper identified and evaluated requirements prioritization techniques proposed between 2007 and 2019, and derived some trends. Limitations of the proposals and implications for research and practice are identified as well.
