Business process reengineering is the fundamental rethinking and radical redesign of existing processes within an organization to achieve significant improvements in key performance indicators - such as costs, quality, speed, and service levels. In practice, this means analyzing how the company operates, identifying inefficiencies, and implementing new, improved processes, often involving organizational, technological, and procedural changes.

Business process reengineering involves:
• Radical change, not just cosmetic improvements
• Process redesign, not just correction
• Improvement in organizational results - costs, quality, speed, customer service
• Changes in structure, technology, and ways of working
• Responding to inefficiencies, competition, and new market opportunities
