Thisbook constitutes the thoroughly refereed proceedings of the 9th InternationalConference on Evaluation of Novel Approaches to Software Engineering, ENASE 2014,held in Lisbon, Portugal, in April 2014.
The 11 full papers presented were carefully reviewed and selected from 58submissions. The papers reflect a growing effort to increase the disseminationof new results among researchers and professionals related to evaluation ofnovel approaches to software engineering. By comparing novel approaches withestablished traditional practices and by evaluating them against softwarequality criteria, the ENASE conferences advance knowledge and research insoftware engineering, identify most hopeful trends, and propose new directionsfor consideration by researchers and practitioners involved in large-scalesoftware development and integration.
