The green transition necessitates manufacturing companies to address climate change and incorporate sustainable and resilient solutions into their production. The best opportunity to achieve such solutions in production is during development, especially in greenfield projects with fewer constraints from existing production solutions. So far, the knowledge of how to achieve this is limited. Therefore, this paper aims to elaborate on how manufacturing companies can attain sustainable and resilient production. The focus is on development practices in greenfield projects and their relation to active ownership, collaboration and learning, potentially supporting the lasting impact of change initiatives. The paper builds on results from a multiple case study, including three greenfield production development projects. A research design, involving 22 semi-structured interviews and four workshops, was applied. An analytical framework was developed to support the analysis, including active ownership, collaboration and learning. In total, 21 different development practices were identified and categorised into active ownership, collaboration, and learning. The paper contributes a new perspective on production development. As an alternative to the traditional planning-and-control perspective, a learning perspective on production development was applied, which is increasingly required for production development processes addressing new domains, such as the green transition.
