This paper focuses on the successful reengineering of the functionality and methods in the highly automated Iowa State University (ISU) Purchasing Card System. The development of ISU's purchasing card system, its processes, and subsequent changes to work load distribution within the system will be discussed. A major component in the reengineering was user involvement. Design was undertaken with active departmental participation. Users not only tested the new system but also contributed to its development throughout the four phases of evaluation, analysis, design, and reconstruction. The effects on normal business operations within the Purchasing department have been noticeable. The "Check With Order" system is used less, the number of departmental orders have been reduced with their corresponding vouchers and checks, and order cycle times have been reduced by half.
