8 For WICSA 2016 the theme
was “Architecting in
time” – exploring the
temporal aspects of software architecture.
continuity, evolution and
decay,
the benefits, consequences
and debt from delaying
decisions,
architecting practices and
experiences in different
software development
processes, or the related
collaborative design activities
that fit into the life cycles of
systems and applications.
