Evaluation is a task most designers, builders, and supporters of information systems agree is significant. However, most information systems evaluations are performance evaluations focusing on the efficiency of the computer system. There is another dimension to the evaluation of the information system that must be considered if computerized information systems (CIS) are to be designed to "fit" an organization: impact evaluations. Impact evaluations are concerned with those effects on an organization which result from the development and use of an information system. The actual task of performing an impact evaluation is hindered by the complexity of the task and by the apparent lack of methods. The complexity is characterized by the difficulties in choosing measures, by the multiplicity and interactions of factors influencing impacts, by the inability to control some of those factors, and by the varying criteria for judging impacts. The lack of methods is characterized by inexperience and insufficient documentation.
