The data in the table below is from a study conducted by an insurance company to determine the effect of
changing the process by which insurance claims are approved. The goal was to improve policyholder
satisfaction by speeding up the process and eliminating some non-value-added approval steps in the
process. The response measured was the average time required to approve and mail all claims initiated
in a week. The new procedure was tested for 12 weeks, and the results were compared to the process
performance for the 12 weeks prior to instituting the change.
