This chapter explains why practices of writing are key for managers and leaders. It draws on two action research case studies that illustrate the needs for and benefits of empirically based knowledge on writing in management and leadership roles. An overview of the state of research shows that, besides multitudes of analyses of managerial genres as final products, only little research has been done to understand and improve the dynamic processes of writing in the field. The chapter concludes that future directions of research must include investigating how the rapidly increasing amount of written management and leadership communication comes into being and how its quality can be improved through management education. The structure of the chapter takes the readers from the topic’s relevance (Section 1) to the fragmentary state of research (2), the two case studies (3, 4), and suggestions to close the research gap through a dynamic approach (5).
