Three categories of misfit have been identified in the software package implementation context. They are Data, Functional, and Output misfits. This study presents a methodology, based on the business form analysis and SEMINT technique, to help identify the Data and Output misfits. With this methodology, the software package acquiring organizations or consulting firms can more easily and systematically identify where the Data and Output misfits are and what the degree of misfits is. These results can contribute to the selection of a suitable software package and are valuable to the decision of either package customization or business process reengineering for the misfits during the package implementation.
