Dr. Dan Power, a professor of Information systems at the University of Northern Iowa, has been, for many years, one of the most outstanding scientists and “advocates” of the DSS movement. Besides writing papers and books in the field, he has created a portal (DSSResources.com) which has been appreciated by many people (consultants, researchers, managers, teachers, and students) that are interested in DSS and look for a reliable source of high quality knowledge. The associated “DSS News” bulletin of Dan Power has contained, since its third issue of the first volume (6th June, 2000) a column entitled “Ask Dan!” to answer various possible questions about DSS.
