What does process efficiency measure in a process?

Process efficiency primarily measures the relationship between value-added time and total lead time within a process. Value-added time refers to the portion of the time spent on a process that directly contributes to creating the product or service that the customer values, while total lead time encompasses the entire duration from the start of the process until its completion, including both productive and non-productive activities.

By focusing on the ratio of value-added time to total lead time, organizations can identify opportunities for improvement, eliminate waste, and enhance the overall efficiency of the process. A higher value-added time in relation to total lead time indicates a more efficient process, as it means that a larger proportion of the time is spent on activities that contribute to delivering customer value. This understanding is crucial in streamlining operations and improving the effectiveness of supply chain management.
