We believe that this understanding is imperative for service providers to make proactive strategies for fostering customers’ intention and actual usage of the SST. The framework makes it possible to understand and predict customer trial related to using self-service technology by thoroughly examining underlying customer readiness degree and use the internet to illustrate how our framework can be applied to study customer behavior related to a specific self-service technology. To analyze the longitudinal effect, a two-stage survey was conducted and lasted for seven months. As it is well known that behavior intention does not necessary lead to actual behavior, our findings offer proactive strategies to service providers in turning intention into actual usage. Implications are discussed for managerial strategy as well as for future research.
