From Magnum Opus to Mea Culpa: A Cautionary Tale of Lessons Learned from a Failed Decision Support System

In this article, I present a case study of a failed decision support system (DSS) and describe the creation and collapse of a decision support project conducted with a client over a number of years. I provide insights and advice on organization, systems, data, and ongoing management and software support, as gleaned from mistakes made during the course of the project. The insights should prove useful for researchers, developers, and students of OR/MS-based decision support systems and the organizations that implement them.
