Following a servitization, many industrial manufacturing firms have recently started the process of developing requirements for digitalization in order to interact more closely with customers through value co-creation. However, many of these requirements, in the context of digital servitization, are presently unexplored. To address this, a qualitative study was conducted using a case study approach, including two case companies. This paper discusses and reviews the requirements for digital servitization to facilitate value co-creation. Specifically, in order to successfully use digital servitization for value co-creation, managers need to consider certain requirements, such as adopting appropriate business models, exploring technical and sales capabilities, and developing customers' and manufacturing firms' mindsets.
