An increased focus on servitization involves ambidextrous challenges – firms need to manage explorative and exploitative service activities simultaneously. Whereas existing literature emphasises the need for organisational separation of service activities, fewer studies address the challenges around managing and organising for different types of service offerings. This paper integrates servitization research with more general management theories on ambidexterity and draws on a longitudinal case study of an industrial manufacturer managing servitization processes. As such, this paper identifies important elements of organisational separation and integration. More specifically, we identify challenges related to the integration of explorative and exploitative service activities, and identify challenges related to the following dimensions: (1) goal setting, (2) timing, (3) tensions, (4) endurance, and (5) magnitude of the integrated units. Furthermore, we discusss servitization as a dynamic process and identify different service activities which were separated, combined, separated again, and finally integrated in the focal firm.
