This book summarizes research done in correlating disintermediation with changes in job satisfaction for remaining members of a disintermediated marketing channel. Disintermediation occurs when a middleman is pushed out of the marketing channel by technological innovation. Disintermediation promises benefits such as lower costs, increased information, increased choice, and flexibility, for producers and consumers. Topics related to disintermediation include such factors as the increased scope of job tasks and responsibilities, the competency for the revised scope of job tasks, the impact of insufficient training, and correlated changes in job satisfaction. Reintermediation and hypermediation are also discussed in relation to disintermediation. Research definitively demonstrates that E-Commerce can produce higher profits and increased employee satisfaction.
