Increasing competition in today’s markets leads to an increasing need for companies to be competitive. One factor that affects how competitive companies can be, is how innovative they are. Companies therefore want to be innovative, which can be challenging. One way of being innovative is to use innovations created by others. When two companies merge, this creates the possibility to use innovations from each other. Before this can happen, the innovations need to be exchanged. In some mergers, after they have merged, the exchange of innovations does not happen. Companies want to know how they can positively influence innovation exchange. By understanding what factors contribute to innovation exchange, companies can design innovation strategies that deal with these factors. This research specifically focuses on mergers between Maintenance, Repair and Overhaul companies that are located in different countries. It was believed that being located in different countries, being in a merger and having a specific company culture might influence which factors affect innovation exchange. The goal of this research is to create a list of success factors for innovation exchange between merged international Maintenance, Repair and Overhaul companies. These success factors are used to understand how merged international Maintenance, Repair and Overhaul companies can exchange innovations. In order to achieve this, the following research question was set up: How can merged Maintenance, Repair and Overhaul companies from different countries exchange innovations between the merged companies? In this definition, innovations are those things that are significantly new for the receiver. In order to answer the main research question, three sub-questions were set up. The first sub-question is: Which factors contribute to the exchange of innovations between companies? This sub-question was answered by a literature review. The second sub-question is: Which factors contribute to the exchange of innovations between two merged international Maintenance, Repair and Overhaul companies? This sub-question was answered by performing a case study research at AirFrance Industries KLM Engineering and Maintenance. The third sub- question is: How can AirFrance KLM Engineering and Maintenance come to the exchange of innovations? This sub-question was answered by deriving a list of do’s and don’ts and recommendations for innovation exchange from the interviews in the case study. The literature review that answers the first sub-question covers literature on standards battles, inter- organizational relationships, social networks and alliance governance. The second sub-question is answered by providing a list of success factors for innovation exchange that were derived from interviews performed at AirFrance Industries KLM Engineering and Maintenance. The interviews from the case study were also used to answer the third sub-question. The list of success factors from sub-question 1 and sub-question 2 were compared and it was checked whether overlap and differences exist between the factors. A set of eight success factors was derived from the case study, which were not found in the literature review. These factors can be taken into consideration by companies trying to exchange innovations. From this comparison, it was concluded that success factors found within a merged international Maintenance, Repair and Overhaul company are largely similar to the general success factors found in existing literature on innovation exchange between companies. Based on the conclusion that the success factors are largely similar and that the new success factors do not oppose existing success factors, it is concluded that the list of success factors derived from the literature review, combined with those found in the case study, can be used by companies to design an innovation exchange strategy or to improve the sharing of innovations within their merged companies. Merged international Maintenance Repair and Overhaul companies, and AirFrance Industries KLM Engineering and Maintenance in particular, can use this set of success factors together with the recommendations in this research and the list of do’s and don’ts, that were mentioned by their own employees, to design an innovation exchange strategy.
