If you want to innovate, then you’d better think about …
§ Architecture … How you build flexible systems
§ Agile … How you develop @ speed
§ DevOps … How you deliver @ speed
§ THE END … and thanks for listening J

Architects’ Perception of Agile Agilists’ Perception of Architecture Leaves key decisions until last possible moment
Locks down key decisions too early
A lack of forethought leads to technical debt BDUF over YAGNI J
A lack of modelling leads to significant rework when software is poorly thought through and does not scale
Comprehensive models slow your development efforts down to a snail’s pace
Architecture and agile – a clash of cultures?

“Scrum is a management and control process that cuts through complexity to focus on building software to meet business needs. Scrum is superimposed on top of and wraps existing engineering practices, development methodologies and standards”. (Schwaber & Beedle, 2002)
“I see two parties not really understanding the real issues at hand, stopping at a very shallow, caricatural view of the “other culture”, not understanding enough of the surroundings, beliefs, values of the other one, and stopping very quickly at judging behaviors.” (Kruchten, 2010)
“Look at a large successful software system and beneath it you’ll find an architecture that’s kept its evolution on track”. (Spinellis, 2010)
