After 17 years, we may be on the verge of a coming-of-age of the pattern paradigm shift. Most programmers still adhere to that vision of simple, individual fixes and symmetric structure: simple and elegant in the small, the way a Lego® is elegant, but unable to capture the daily complexity of software design. Today’s systems thinkers are starting to think in terms of complex grammars of patterns, called pattern languages, that capture the design process for truly complex systems.
