Episode 142: Sustainable Architecture with Kevlin Henney and Klaus Marquardt

This is another episode recorded at OOP 2009, thanks to SIGS
Datacom and programme chair Frances Paulisch for making this
possible. Here is the abstract from the conference program: Many
software systems have fragile architectures that are based on
brittle assumptions or rigid architectures that reduce options and
make change difficult. On the one hand, an architecture needs to be
fit for the present day, suitable for immediate use, and on the
other it needs to accommodate the future, absorbing reasonable
uncertainty. However, an approach that is overly focused on today's
needs and nothing more can create an inflexible architecture. An
approach that becomes obsessed with possible future changes creates
an overly complex architecture that is unfit for both today's and
tomorrow's needs. Both approaches encourage an early descent into
legacy for a system. The considerations presented in this talk
reflect an approach that is more about thinking in the continuous
present tense than just the present or the future tense. This
includes principles from lean thinking, practices common in agile
processes and techniques for loosely coupled design.
