Business process redesign (BPR) involves completely overhauling an organization's key business processes to achieve significant improvements in metrics like return on investment, costs, and service quality. It requires analyzing all business processes to identify those that are critical, like manufacturing, production, sales and customer service. The redesign process should include setting clear objectives, analyzing current processes, consolidating workflows, empowering staff, and monitoring changes. BPR can be costly and disruptive but is effective for organizations aiming to break patterns and meet ambitious goals.
