Building Digital Infrastructures: Towards an Evolutionary Theory of Contextual Triggers

Past IS research suggests it is challenging to build digital infrastructures and then make sure they grow. While more users, innovative services, and new partners spur infrastructure evolution, we know little of the specific contextual triggers that set these generative mechanisms in motion. To this end, we conduct a case study of a digitalized public transport infrastructure to identify such triggers and explore their impact on its evolution. Our study contributes to the extant literature on digital infrastructure evolution in two distinct ways. First, we analyze, define, and propose three contextual triggers that improve our understanding of the generative mechanisms behind infrastructure development and growth. Second, we rely on this conceptual basis to sketch out the initial contours of a novel evolutionary theory of digital infrastructure triggers. \
