✦ Synopsis
Recent breakthroughs in computing technology have created a set of perplexing new problems for information systems (IS) professionals. These revolve around decisions to be made about replacing current systems with newer technology, upgrading existing systems, and migrating to other platforms or environments. Many decision makers must rely on subjective assessments, such as their instincts or the recommendation of vendors rather than on an objective analysis of their inlbrmation needs and how they can be met by various system alternatives. A model to quantify these issues, providing an objective measure for comparing system alternatives, including migration, would be valuable. Such a model is demonstrated here; it uses the Shannon-Weaver entropy model in conjunction with quality measures to quantify actual and potential system effectiveness.
