What business process improvement model is known for dramatic changes aimed at gaining productivity and efficiency?

The business process improvement model that is known for dramatic changes aimed at gaining productivity and efficiency is business process reengineering. This approach focuses on rethinking and redesigning the way work is done in an organization to achieve significant improvements in critical areas such as cost, quality, service, and speed.

Business process reengineering involves radically rethinking current processes, often through the use of technology, to eliminate inefficiencies and improving performance. Instead of incrementally making small changes, it emphasizes substantial overhauls of existing processes to leverage new technologies or methodologies, which can lead to transformational improvements in how an organization operates.

In contrast, the other choices represent different methods of improvement: business process automation typically involves the use of technology to automate standard processes but doesn’t necessarily require a complete overhaul. Continuous improvement focuses on ongoing incremental improvements rather than radical changes. Total quality management emphasizes long-term success through customer satisfaction and involves every member of the organization but does not aim for dramatic transformation of business processes.
