Rapidly changing environments and increasing costs serve as significant driving factors necessitating accelerated information technologies (IT) planning, development and operations within the enterprise. To achieve greater speed, minimizing delays in IT delivery is essential. In this case study, we identified 40 factors limiting the speed of enterprise IT in different areas of a very large enterprise on the basis of expert interviews. We structured these limiting factors into nine categories and describe how they affect the speed of enterprise IT. The results offer multiple starting points for addressing these factors and to increase the speed of enterprise IT by improving processes and structures, advancing employees’ skills and by further developing enterprise architecture management (EAM) support for digital transformation projects.
