The paradigm shift introduced by Industry 5.0 has intensified the focus on enhancing worker autonomy through new technologies within decision-making contexts. Despite the growing body of research on this phenomenon, there is a notable lack of guidance on the appropriate methods for investigating this issue. This literature review aims to identify and characterize existing research and evaluate the most commonly used methods. The findings reveal various methods, each with significant limitations, and uneven coverage of new technologies studied to enhance decision-making processes and autonomy at work. Case studies emerge as the predominant method, but their inherent characteristics and opportunistic nature present significant limits to the establishment of structured research, enabling a comprehensive and generalizable study of such issues. However, the adoption of use cases is now emerging as a promising alternative to meet these challenges, but the development of a structured and coherent research framework is still needed.
