Since their creation in the early 1960’s, decision support systems (DSSs) have evolved over the past 4 decades and continue to do so today. Although DSSs have grown substantially since its inception, improvements still need to be made. New technology has emerged and will continue to do so and, consequently, DSSs need to keep pace with it. Also, knowledge needs to play a bigger role in the form of decision making. We first discuss design and analysis methods/techniques/issues related to DSSs. Then, the three possible waysto enhance DSSs will be explored.
