Cognitive Power for Management Through Reasoning Support

IISR methodologies are roadmaps for infor-mation systems research that are adapted to cho-sen contexts and state-of-the-art theory to develop IS support that can give best possible guidance for (often consequential) managerial decisions. The paper works out guidance for efficient, effective or explicable management decisions. The general principles and the development history – from the early days of Operational Research and Management Science to digital ecosystem platforms for management – show how requirements on ISR methodology have evolved. An ISR methodology for the 2030’es will still rest on the decision analysis tradition to support efficient and effective managerial decisions in relevant problem-solving contexts. The flexibility and ideology of decision support systems will prevail to show how operating managers can boost performance with IS instruments, tools and technology. Digital ecosystem platforms that support the use of reasoning artificial intelligence will continue, expand and improve on the DSS ideology.
