The literature is rich with evidence of SSTs importance to forming customer satisfaction, but there is scant empirical evidence pointing to the role of co-production in forming customer satisfaction in online service encounters. It is hypothesized that within the online service encounter, features of co-production are significant predictors of customer satisfaction. Survey data show that customers differentiate the service features of co-production from the service features of SSTs. Furthermore, these two service features have identifiable drivers to customer satisfaction. Theoretical and practical implications are discussed. Doctorate of Management Programs Show less
