Modeling and Evaluation of Information Systems

  • Oscar Barros

Abstract

A general graphical model for organizational information Systems (IS) is proposed. This model is based on systems theory and general patterns of organizational processes regulation derived from empirical observation and experience. It includes generalized decision making and data manipulation functions to regulate generalized organizational processes through flows of information. The general IS model is shown to serve as a basic pattern to approach the design of any IS. In particular, it is shown that alternative IS structures or designs can be derived from it. Structures not only include information that will be computerized, but also the prescription of the decision making behavior of the information users. This problem of jointly studying alternative behavior-sets of information or structures can be related to and supported by organizational design theory. The existence of alternatives leads to a problem of evaluation for which a quantitative modeling approach is proposed. Connection with organization theory allows base modeling on the measuring of organizational effectiveness of each alternative.
