A cost-benefit evaluation method for web-based information systems
Cécile L. Paris, Nathalie Colineau, Ross G. Wilkinson · 2009
Most evaluations of web-based information systems are done with respect to their effectiveness in supporting users in finding and exploring the information they need. We believe (1) that we need to move beyond task effectiveness and look at the whole-of-system effectiveness, and (2) that we must balance benefits with costs. We propose a method that provides guidance in whole-of-system evaluations, explicitly considering all participants and both sides of the "bang for buck" equation.
