Systematic Creation of Cumulative Design Science Research Knowledge with a Case Study in the Field o a process model for digital innovation. This results in the enhanced presentation of a new design science approach to the engineering of digital innovation that systematically builds up information systems design theories. We evaluate this combined new method artifact in a case study for an innovat
