Notwithstanding the pervasiveness of enterprise systems, their selection and implementation is still being perceived as problematic if not risky. Research in the tradition of requirements engineering argues that its insights will ameliorate this condition. Yet, the context of enterprise systems has outmoded requirements engineering from the viewpoints of both method and practice. Theoretically, analysis of the presuppositions of requirements engineering has identified a methodological turn that proffers a cogent explanation of the empirical findings regarding today’s practices. The conclusions are of immediate relevance for organisations, since they present an updated view of current practices of selection and implementation of enterprise systems.
