In this paper, we briefly describe IS agility related research in four established IS research areas: IT infrastructure, IS development, IS organization, and IS personnel. We present a systematic literature review of articles published in leading scientific IS journals during the years 1990-2013. The main contribution of the paper is in the summary of research methods and results of agility related research in the four research streams. Our analysis will provide researchers with a foundation of prior research when designing future studies. Additionally, the paper raises concerns that the dominance of two research streams (i.e., flexible IT infrastructures and agile IS development methods), may overshadow the role of IS personnel characteristics and IS organisation design in agility studies. Future IS agility research could also benefit from studies adopting a broader theoretical perspective to integrate concepts and findings across all four research streams.
