Our article provides insights into which critical success factors (CSFs) for digital transformation projects are considered particularly relevant from the perspective of companies. To this end, we used an online survey addressing German companies with an existing set of CSFs. The aim of our study was to obtain a practice-oriented ranking to derive approaches for further research into CSFs in digital transformation. Our study shows that it is primarily CSFs in the dimensions of Corporate organization and Technology that are considered to be particularly relevant. For example, when asked about important CSFs, the companies stated that digital transformation projects require besides other factors a suitable Corporate culture, Top management support, and a Unified digital corporate strategy/vision. Thereby, this article contributes to CSF research in the context of digital transformation with profound experience and orientation knowledge. This will make it possible to develop practical recommendations for action and assistance in shaping the digital transformation.
