Is qualitative research the missing piece in logistics innovation? This paper argues for the increased use of qualitative research methods, particularly action research case studies, to advance logistics research and address real-world logistics challenges. By examining the limitations of the current dominance of quantitative research, the author proposes a balanced approach incorporating both quantitative and qualitative methods to foster holistic and systemic thinking. The paper highlights that logistics problems are often ill-structured and multi-faceted, requiring multi-disciplinary approaches. Action research case studies are particularly well-suited to this applied field because they strive to advance both scientific knowledge and practical application. The study emphasizes that logistics research should reflect this approach, which is currently lacking in published works. To promote the use of qualitative methods, this paper calls for a deeper understanding of research paradigms and their influence on research evaluation. The author advocates for clear definitions of case studies in journal articles and the development of specific criteria for evaluating action research. By embracing a broader range of methodologies, logistics research can better address complex challenges.
