Abstract : The development of time-shared computer systems has led to major technical and philosophical changes in the computer field in this decade. A large number of designers, manufactureres, and users of such systems have expended great amounts of effort in the development of the capabilities of the computer and the means to use it. However, little or no effort has yet been expended to evaluate these systems in terms of their usefulness for present or future customers. The research reported here has focused on the development of a methodology through which time-shared computer system usage can be evaluated. It is based on a study of the characteristics and design of present and proposed computer systems, as well as relevant behavioral theory and research. Five categories of variables are included in the resulting methodology, namely those which are measures of: (1) the cost of using the system; (2) the performance produced through the use of the computer system; (3) the speed with which results could be produced; (4) the amount of learning resulting from the use of the computer system; and (5) the attitudes of the users of the computer system.
