Which approach should be applied to improve a business process that has delays due to tasks being performed in a serial manner?

Improving a business process that experiences delays from tasks being performed serially involves modifying the order in which these tasks occur. By changing the task sequence, it's possible to identify and implement a more efficient workflow where dependent tasks can be handled simultaneously or restructured to minimize wait times. This leads to a reduction in overall process duration and enhances productivity.

In cases where tasks are dependent on one another, it may also be beneficial to investigate parallel processing opportunities. However, simply adapting or automating tasks won't necessarily eliminate delays caused by their current sequence. Redefining boundaries generally addresses the scope of a process rather than its operational flow, and while automation can improve efficiency, it does not directly resolve the underlying issue of the serial task arrangement. Therefore, changing the task sequence directly targets the cause of the delays and presents a practical solution for improvement.
