Presentation: "Panel: Does Architecture Quality Matter?"
Time:
Wednesday 16:00 - 17:00
Location:
Conference Hall
Abstract: Experts never become tired to emphasize that software
architectures should meet appropriate qualities to be successful
and sustainable, such as flexibility, performance, robustness,
and so on. Also, a lot of design tactics, patterns, and practices
are known to meet such architecture qualities.
On the other hand, experience shows that most "real" software
architectures follow another pattern: the "Big Ball of Mud"
(see http://en.wikipedia.org/wiki/Big_ball_of_mud -- Joseph Yoder
and Brian Foote), a casually, even haphazardly, structured system,
whose organization is dictated more by expediency than design.
Such a system works, somehow and for some time, but its maintenance
and evolution is a costly nightmare.
How can it be that theory obviously deviates so much from practice?
From a pessimistic perspective we can even ask: Do we actually need
architecture quality? Isn't architecture quality simply a marketing
term, or something a project can try to achieve, but if it does not
work out, does not really matter?
On this panel, world-class software architects discuss, whether or not
architecture quality is really needed in practice, and based on their
position explore the fine balance between too little and too much
architecture quality -- to define systems that are good enough!
