A Methodology for Multi-Criteria Information System Design.
Chandler, John S.; DeLutis, Thomas G.
The complexity of the design problem for modern computer based information systems has increased significantly over its predecessors. The problem presented to the designer is to configure a system which satisfies the user criterion while achieving system resource related performance criteria. The purpose of this paper is to present an evaluation technique for addressing the problem of multiple criteria performance evaluation of information systems. The goal of this technique is to provide the designer with an evaluative procedure which: (1) seeks to establish a causal relationship between user goal attainments and system resource expenditures, while allowing for the collection of heretofore hard to obtain evaluation information; (2) measures the impact of individual user classes on internal system performance; and (3) identifies those information system activities which should be modified to improve system performance related to those goals. All of this is achieved by maintaining resource utilization statistics on a user class basis. It is thought that such an evaluation framework is capable of eliminating many of the numerous non-satisfactory designs by directing the designer to the most advantageous ones. (Author/DAG)
