Digital Transformation is one of the megatrends to re-shape industries, non-profit sectors, higher education, and even societies. Digital technologies merge with physical production processes provoking changes in value creation processes. These changes may lead to positive effects such as more effectiveness, revised business models, and closer customer contact. However, there are also negative effects hindering the digital transformation journey. As many firms still struggle, it is essential to understand the barriers which slow down or even stop a digital transformation. Based on qualitative data from 525 respondents working in different sectors, we reevaluate and extend an existing model by using a triangulation approach. The result is a holistic socio-technical model of the barriers to digital transformation consisting of seven distinct dimensions. The model can serve as input for future research instruments. Firms can use it to reflect barriers in their digital transformation.
