Business process reengineering (BPR) involves fundamentally rethinking and radically redesigning business processes to achieve dramatic improvements in critical performance measures like cost, quality, service and speed. It aims to help companies fundamentally change how work is done to better support the organization's goals and become more efficient and effective. The key steps in BPR include selecting processes for reengineering, understanding the current processes, developing a vision for improved processes, creating an action plan, and executing the plan. BPR is different from continuous improvement in that it focuses on radical rather than incremental change and redesigning from a blank slate rather than refining existing processes.
