For MIS specialists and nonspecialists alike, teacher and consultant Dan Power provides a comprehensive, readable, understandable guide to the concepts and applications of decision support systems. Not only does his book help enhance your DSS design and development capabilities, it also shows how DSS can buttress organization goals and the impact DSS have throughout organizations and at all levels of management. Power defines DSS broadly: interactive computer-based systems and subsystems that help people use computer communications, data, documents, knowledge, and models to solve problems and make decisions. He focuses his book on practical applications, but also includes important and relevant empirical research and underlying theory. His book thus provides enough concrete detail to help grasp the essentials of DSS, but it also gives advanced tips and suggestions to DSS specialists too. For people trained in fields outside the information sciences, Power's book is especially valuable. It gives them the knowledge they need to work with their MIS colleagues and to truly appreciate the management value of information technology overall.
