The 13th Working IEEE/IFIP Conference on Software Architecture (WICSA) is the premier venue for practitioners and researchers interested in Software Architecture. Since its inception, WICSA has functioned as a working conference, where researchers meet practitioners and where software architects can explain the problems they face in their day-to-day work and try to influence the future of the field. In addition to traditional conference keynotes and paper sessions WICSA includes interactive working sessions where practitioners and researchers discuss their experiences to understand the current state of the field and identify opportunities to impact the future. The theme for 2016 is Architecting in time.
