Many studies have investigated the effects of information technology (IT) in achieving organizational performance. However, despite substantial IT investments, organizations often fail to improve organi-zational performance using IT. This failure could be the result of a lack of Business-IT alignment. Re-cently, scholars and practitioners have adopted a complexity science approach to better address the many interwoven IT, organizational and environmental turbulence challenges. These efforts resulted in the emergence of the complexity-based concept of co-evolutionary IS/IT-alignment (COISA). COISA involves “the series of coevolutionary moves that makes IT aligned over time.” However, the notion of COISA remains conceptual, and further operationalization in preparation for more empirical evidence seems appropriate. Therefore, this study aims to provide further clarification on the conceptualization of COISA in turbulent environments. We conducted a structured literature review using a theoretical foundation of Complex Adaptive Systems theory. In this effort, we developed a COISA model composed of five continuous alignment processes characterized by co-evolutionary moves toward alignment, situated in two organizational contexts. This model provides a basis for further empirical re-search on COISA.
