Requirements Engineering for Embedded Systems: A Systematic Literature Review

Context: Most problems that occur at system delivery of Embedded Systems (ES) are related to requirements misconceptions in capturing requirements. Hence, a Requirements Engineering (RE) process is crucial to meet time, cost, and quality goals. Objective: We investigate the studies to analyze and understand how the RE approaches are used for embedded systems development. Method: We conducted a Systematic Literature Review (SLR) as the basis for our work. Results: We uncovered 92 studies and found out the RE phases that are attracting more attention, the main requirements modeling styles used, the types of requirements modelled, and the existing challenges/problems. We also proposed a research agenda. Conclusions: This paper is a step towards developing a body of knowledge in RE for ES that is derived from a large-scale SLR. We believe the results will benefit both researchers and practitioners.
