This article suggests that failure to address the uncertainty and equivocality that exist during the development and implementation of a new management information system is a major reason why projects fail. Uncertainty and equivocality occur naturally at different intensities in the various stages of the systems development life cycle. They can also be introduced into the situation based on the level of technology of the new system.
