In a study of the predictors of success and failure in implementing technology, the author examines the introduction and use of profiling, an expert system intended to aid the insurance sales process at four insurance companies. Lutheran Brotherhood, National Mutual, Prudential, and Sun Alliance tried to get more than 5,000 field salespeople to implement Profiling. The study results indicate that in implementing a radically new technology, managers need to assemble "constellations" of actions, consider the' political ramifications throughout the organization, manage the momentum of the project, and work to achieve economies of scale.
