This document provides an overview of business process design. It defines a business process as a network of connected activities that transform inputs into outputs to satisfy customer needs. Process design aims to configure this network efficiently. Inefficient processes often exist because they emerge through incremental changes rather than careful design. Classifying activities as value-adding, non-value adding, or necessary for business is important for identifying areas for improvement. An insurance claims handling example illustrates potential benefits of redesign like reducing customer wait times from 10 days to 1 day.
