Service productivity and service quality: A necessary trade-off?

In this paper, in order to trace some theoretical answer to the above questions, a managerial model based both on service science and production economics will be proposed. The model aims to find out some key causes that allow to explain the foundations of the mentioned trade-off and the potential conditions for its overcoming; moreover, such model will be employed in order to integrate services' productivity function with new variables and to provide some managerial guidelines for improving service management.
