Many organizations report difficulties in integrating lean. A possible cause could be that methods and tools do not support each other. The purpose of this research is, therefore, to explore the nature of the connections within the system. Understanding these provides practitioners with a better way of defining their system and offers researchers a conceptual model with a new way of understanding a company-specific production system (XPS).

The study is designed as a multiple case study with three organizations and, in total, 25 lean experts serving as respondents.

The connections between the elements of an XPS act as a duality based on a problem–solution (P–S) relation. These are categorized according to complexity and can be mapped into a conceptual model, where the connections can be either symmetrical or asymmetrical.

The results provide a method to analyze causes and effects in an XPS and a conceptual model. Given the limitations of a multiple case study, future research should explore connections depending on a broader variety of contextual conditions.

The results present a way to avoid a cherry-picking problem through understanding connections between elements in an XPS. This provides a new way to understand the weaknesses of an XPS.

The research provides a new approach with insights on how to conduct research in lean production by facilitating how to understand and interpret connections between elements in a system.

The purpose of this paper is to advance the understanding of paradoxes, underlying tensions and potential management strategies when integrating digital technologies into existing lean-based production systems (LPSs), with the aim of achieving synergies and fostering the development of production systems.

This study adopts a collaborative management research (CMR) approach to identify patterns of organisational tensions and paradoxes and explore management strategies to overcome them. The data were collected through interviews and focus group interviews with experts on lean and/or digital technologies from the companies, from documents and from workshops with the in-case researchers.

The findings of this paper provide insights into the salient organisational paradoxes embraced in the integration of digital technologies in LPS by identifying different aspects of the performing, organising, learning and belonging paradoxes. Furthermore, the findings demonstrate the intricacies and relatedness between different paradoxes and their resolutions, and more specifically, how a resolution strategy adopted to manage one paradox might unintentionally generate new tensions. This, in turn, calls for either re-contextualising actions to counteract the drift or the adoption of new resolution strategies.

This paper adds perspective to operations management (OM) research through the use of paradox theory, and we (1) provide a fine-grained perspective on why integration sometimes “fails” and label the forces of internal drift as mechanisms of imbalances and (2) provide detailed insights into how different management and resolution strategies are adopted, especially by identifying re-contextualising actions as a key to rebalancing organisational paradoxes in favour of the integration of digital technologies in LPSs.
