Today's organizations struggle to remain competitive due to challenges regarding changing technology and customer expectations. Although many organizations strive to digitally transform their business, they still fail due to digital incompetence, unpreparedness and ignorance. Thus, the thesis aims to investigate how to transform organizations into digital businesses, the required competencies of digital leaders and the interaction between digital leadership and digital transformation strategies. For this purpose, we conduct a systematic literature review to build a conceptual framework that, by hypotheses and propositions, may serve as a point of departure for future empirical research. With this model, we propose that leaders with higher levels of digital leadership, in terms of management skills, customer skills, digital skills and organizational skills, have a positive influence on the establishment of digital transformation strategies. Thus, this thesis contributes to an understanding of digital leadership, digital transformation strategies and the interlinkages between these.
