Reengineering is most commonly defined as the redesign of business process—and the associated systems and organizational structures to achieve a dramatic improvement in business performance. BPR has been described as a radical new approach to business improvement, with the potential to achieve dramatic improvement in business performance. BPR should not be considered downsizing, restructuring, reorganization, or new technology. It is the examination and change of five components of the business strategy, process, technology, organization, and culture. Many companies continue to experiment with reengineering, even if they have failed in previous attempts.
