More and more Agile projects are seeking architectural roots asthey struggle with complexity and scale - and they're seekinglightweight ways to do it
* Still seeking? In this book the authors helpyou to find your own path
* Taking cues from Lean development, they can help steeryour project toward practices with longstanding track records
* Up-front architecture? Sure. You can deliver anarchitecture as code that compiles and that concretely guidesdevelopment without bogging it down in a mass of documents andguesses about the implementation
* Documentation? Even a whiteboard diagram, or a CRC card,is documentation: the goal isn't to avoid documentation, but todocument just the right things in just the right amount
* Process? This all works within the frameworks of Scrum,XP, and other Agile approaches

James O. Coplien is a writer, lecturer, and researcher inthe field of Computer Science. He has made key contributions in theareas of software design and organizational development, softwaredebugging, and in empirical research. His early work on C++ idiomswas one of the three primary sources of the popular DesignPatterns. His work on Organizational patterns was an inspirationfor both Extreme Programming and for Scrum. Cope was a foundingMember of Hillside Group with Kent Beck, Grady Booch, WardCunningham, Ralph Johnson, Ken Auer and Hal Hildebrand. He isresponsible for starting up several of the conferences in thePattern Languages of Programming (PLoP) conference series and is alongstanding pattern author and PLoP shepherd.
