form only given. The engineering of web and mobile applications requires methods tailored to these domains to guarantee the required quality. The aim of this thematic track was to solicit contributions on how to properly integrate quality evaluation techniques into web and mobile engineering. From the quality in Web engineering perspective, this includes contributions on how to leverage Webbased systems quality with Web Engineering techniques, as well as on how to integrate quality assurance in the web engineering lifecycle itself. From the quality in mobile engineering perspective, this includes methods to guarantee the quality of mobile apps by construction like tailored requirements engineering, UI and interaction design, or architectural design methods, as well as analytical quality assurance methods like testing and inspection methods tailored to the mobile domain. During the track ten papers were presented.
