 digital transformation, DT, projects are complex and often unsuccessful due to the lack of guidelines and best practices. To address this issue, this paper conducts a systematic literature review to identify guidelines and best practices from existing papers. Eight main guidelines are identified and expanded upon with best practices. The results are eight tables providing an overview of the commonly agreed upon best practices for each DT guideline. This paper serves as a seminal point for future research on how these guidelines are followed in practice, how these differ per industry, and what their impact is on the overall success of DT projects.
