INFORMATION SYSTEMS EVALUATION AND EFFECTIVENESS

摘要

Information Systems (I.S's) Evaluation is traditionally based on its development and operating cost. This is very natural, since with the new system a higher effectiveness of the corporation in the specific domain is aimed at. There are, however, cases in which the new system offers, in addition to the economic advantages for which it has been planned, more benefits which are not apparent at first sight. With regard to the above concept, in this paper are examined: the general aspects of I.S's evaluation - the criteria for I.S's evaluation - the qualitative and quantitative measurements for I.S.'s Evaluation - the I.S.'s Reliability, Operational Availability and Effectiveness.
