The adoption of new technologies is one of the tasks affecting not only the IT departments but all related business functions. However, the impacts of technologies are different and so are the adoption processes. One of the most relevant technological innovations at present is blockchain. However, unstructured experimentation with the technology, uncoordinated efforts across units or missing understanding of how blockchain connects with the firm’s current information systems hinder the adoption of blockchain. Hence, firms need to clearly understand the dimensions of the adoption across the organization and what is decisive within these dimensions. Based on an explorative study with in-depth interviews in nine cases with experts in the field of adopting blockchain technology, we distil seven dimensions of the organizational adoption of blockchain. Furthermore, we analyse the organizational dimensions and, per dimension, derive factors of success or failure of the adoption of blockchain.
