This study examines the modes of action for integrating Lean Management with Industry 4.0 through the lens of the Dynamic Capabilities theory. In addition, the gaps in the present knowledge base are aggregated, and a research plan for the future is proposed. The study is based on a Thematic Analysis of 16 in-depth interviews with industry experts engaged in large German manufacturing firms. Unlike previous analyses, this study concentrates on the ‘how’ level to inform practical executions and support firms in their journeys of integrating these two transformational paradigms of Operations Management. The findings indicate a strong methodological and capability-driven focus across the views of industrial experts. Furthermore, modes of action as moderators of success were derived from proposing a processual model to be evaluated through quantitative research. Identifying gaps in the present knowledge base and defining a research agenda centred on operational principles opens up opportunities for future research with significant practical value.
