In the study of business management, process integration has become an interesting area of research that affects analysts studying and working on existing system plans. Process integration aims to investigate relationships across a business compendium to produce classifications and merge similar activities into a standardized system. Integration is the process of merging elements from two similar antecedent processes to create a single process that can be used to replace the original processes. This paper proposes a practical method for process integration and provides a theoretical framework and metrics for business process integration assessment. In the provision of metrics that take into account similarity of activities within processes we are able to offer solutions that provide minimal change reducing change costs, and minimizing change impact risks.
