Creating a Functional Interdependency Map for Supporting the “Act of Improvement” in Business Process Improvement Projects
Business process improvement (BPI) is of high priority for practitioners. But especially the most value-adding phase in a BPI project, namely the “act of improvement”, is insufficiently supported despite the many existing...
