Business process reengineering (BPR) is a management strategy that focuses on analyzing and redesigning an organization's workflows and processes to fundamentally change how work is done. It aims to improve customer service, cut costs, and increase competitiveness by starting with a high-level assessment of the organization's mission and customers, and recognizing that current processes are often fragmented across functions. Reengineering maintains that only redesigning whole processes, not just sub-processes, can achieve the greatest benefits for the organization and its customers.
