How information systems (IS) affect organizations and enable radical organizational change has been explored from a variety of perspectives. Through a case study in the investment banking industry, we will examine the changing nature of ISñorganization relationships focusing on the crucial role that IS play and will continue to play as organizations strive for competitive advantage in a global economy. By expanding on the organizational emergence theoretical framework of Truex et al. (1999) and drawing on the technology evolution literature, we aim to gain a deeper understanding of the coevolution between an IS and an investment banking company.
