The first International Network for Service Research workshop was held at Karlstad in September 2014, with 37 renowned service researchers from 13 countries participating. The purpose of the network was to encourage collaboration across the various research centers and to strengthen the area of service research. One of the key areas to focus on for the future development of our field is theory. Consequently, the workshop included a collaborative session that focused on "Enhancing Theory Development in Service Research". This e-book includes papers that were presented at the first International Network for Service Research workshop.
