Exception‑Based Approach for Information Systems Evaluation: The Method and its Benefits to Information Systems Management

Abstract

Exceptions are events that cannot be handled by an information system by following normal processing rules. Exceptions arise for two main reasons: flaws in system design and post implementation changes in the system domain. Only few exceptions should arise in an information system serving its user community well. In practice, this is rarely the case and exceptions are sometimes rather common even with routine processes. In this paper, an exception‑based approach to evaluate information systems is presented together with practical examples of its use. The benefits of the analysis to information system management are elaborated on.
