Information technology has often been argued to be central to the development and implementation of redesigned business processes from the first appearance of the term ‘business process re-engineering’. Yet, the contribution of IT to process redesign is not well understood. To add to the confusion in practice, IT has also found to be the principal impediment to the realization of redesigned processes. This paper examines the rôle of IT, both as a BPR project support tool and as an infrastructural enabler of realigned enterprise processes. It places IT firmly within the context of holistic BPR project methodologies and presents the results of a study on the features of automated process redesign tools. It discusses the process enactment capabilities of IT and explores the difficulties of developing process support systems, as well as strategies for migration from legacy systems platforms. © 1997 John Wiley & Sons, Ltd. and Cornwallis Emmanuel Ltd.
