Enterprise architecture (EA) offers ways to steer and guide the design and evolution of the enterprise including its information technology (IT). One of the outputs of EA is improved decision-making about IT. Objective: This study aims to provide EA researchers and practitioners with insights into how IT decision-making actually takes place and what that means for them. Method: A systematic literature review was conducted in order to find and analyze primary studies about IT decision-making. Results: We found that IT investment and prioritization is by far the largest decision category. Money seems much more important than content. The IT decision-making process itself is subject to different variables and factors making every IT decision unique. We also found that both rational and bounded rational approaches are used in IT decision-making. EA has not a prominent role in IT decision-making. Conclusions: IT decision-making is a messy and complex process where money plays a prominent role. We argue that, if enterprise architects want to influence IT decision-making, they should follow the money by combining content with investment planning and prioritization. Further research is required into what distinguishes enterprise architects that are successful in IT decision-making, from those that are less successful.
