Although the value of geographic information systems (GIS) technologies is recognized by practitioners and educators alike, GIS instruction has yet to make significant inroads into business curricula. In this article, the authors discuss the constraints of integrating GIS tools into business education. They develop a prototype module for overcoming these constraints and discuss a retail site selection module and its implementation in a retail management course. Faculty and student evaluations of this exercise serve as the basis for assessment of this approach and recommendations for future development of GIS instruction in business education. The San Francisco Site Selection Project is appended. (Contains 1 figure.)
