Final answer:
The reworking of a bank's mortgage application process with the help of computer software and the combination of steps to enhance efficiency is an instance of Business Process Redesign.
Step-by-step explanation:
When a bank reworks its mortgage application process to improve efficiency through computer software and reduction of bottlenecks, this aligns with the concept of Business Process Redesign (BPR). BPR aims to restructure the organization's workflow to make it more integrated and efficient. The bank is not only automating certain tasks but also rethinking and restructuring the steps involved in the application process for mortgages to achieve a seamless process, which constitutes a redesign beyond simple automation or incremental improvements associated with Total Quality Management (TQM) or Six Sigma.
