The goal of the MobileDeli 2015 workshop was to establish a vibrant research community of researchers and practitioners for sharing work and leading further research and development in the area of mobile software engineering. At the workshop, participants discussed how other technologies (e.g., DSLs, cloud computing) drive new capabilities in mobile software development. The workshop attendees examined the lifecycle of mobile software development and how it relates to the software engineering lifecycle. Working group discussions and activities also occurred where attendees explored and evaluated existing techniques, patterns, and best practices of mobile software development.
