A Multi-Perspective Review on Embedded Systems Quality: State of the Field, Challenges, and Research Directions

Abstract

The use of embedded systems has increased significantly over the last decade with the proliferation of Internet of Things technology, automotive and healthcare innovations and the use of smart home appliances and consumer electronics. With this increase, the need for higher quality embedded systems has increased. There are various guidelines and standards, such as ISO/IEC 9126 and ISO/IEC 25010, for product quality evaluation. However, these guidelines cannot be directly applied to embedded systems due to the nature of these systems. Applying traditional quality standards or guidelines on these systems without modification may degrade the performance of the system, increase memory usage or energy consumption, or affect other critical physical metrics adversely. Consequently, several models and approaches have either been introduced or have adopted existing guidelines to produce high-quality embedded systems. With this motivation, to understand the state of the art, and to identify the research directions in the field, we conducted a systematic literature review (SLR). In our research, we have investigated studies published from 1980 to 2024 and provided a comprehensive review of the scientific literature on quality models, quality attributes, employed practices, and the challenges, gaps, and pitfalls in the field.
