Facilitating interactions is crucial during organizational transformations. This is particularly important in the context of post-merger integration where the combination of two formerly independent organizations need to create value. We explored the actions taken by key individuals that made a difference during post-merger integration within a case study. These actions which facilitated interactions were identified as “buffering”, helping to reduce intra-group and inter-group tensions, and “bridging”, helping to maintain continuity between past and present to provide a sense of stability and direction. Through these actions global leaders can make a difference for both the individuals and groups during post-merger integration.
