Understanding how information technology (IT) transforms individual, organizational, and societal ways of being is becoming increasingly complex and discourses on IT present opportunity and risk as two inseparable sides of the same phenomenon. Among the themes that extend throughout practitioner literature, and have emerged gradually in the academic literature as well, ERP projects are illustrative of the opportunities and risks IT presents. In this essay, I propose a discussion centered on the ERP phenomenon as an exemplary illustration of a major question: why does rhetorical closure dominate some discourses about IT when, in fact, all technologies are social constructions, always open to change? Dealing with ideas borrowed from structurational and social constructivist streams of thinking, I identify occasions of ERP package negotiation and change at three levelsósegment, organization and individualódemystifying the rhetorical closure that seems to dominate public debate.
