Business Process Re-engineering (BPR) is a strategic approach that focuses on the radical redesign of business processes to achieve significant improvements in performance metrics like cost, quality, and speed. It involves a thorough assessment of an organization's mission and customer needs, followed by the rethinking and redesign of processes for greater efficiency, often leveraging modern information technology. BPR aims to break down functional silos within organizations to create more agile, effective operations that can better meet market demands.
