Within an international manufacturing network (IMN), one particular factory, called the lead factory is responsible for development of new products, processes and technologies as well as transferring these to the subsidiaries within the IMN. These responsibilities require coordination, which is found difficult even in the best-performing companies due to its complexity. When the responsibility for development of Industry 4.0 technologies are included such as cyber-physical systems and Internet of Things the complexity increases further. Therefore, the aim of this paper is to identify what are the challenges with coordination of technology development and transfer of Industry 4.0 technologies in IMNs. Accordingly, a real-time embedded case study was carried out with six manufacturing companies. One major finding is that development of Industry 4.0 technologies does not fit the current way of organizing technology development at lead factories. Another finding is that several of the identified challenges connected to technology development can be derived from a lack of a long-term strategy ensuring competence for future needs.
