Emergent Design and Architecture

!  Complexity and changing requirements makes centralized decision making inefficient

!  Design by those who implement specific functionality !  At scale, some intentional architecture necessary –  Excessive redesign slows time-to-market –  Some capabilities can/should be anticipated –  Teams not always able to synchronize, thus creating

divergence –  Cross-cutting architectural and user requirements

Intentional Architecture

!  Just in time architectural elaboration !  Assumes incremental implementation !  Relies on feedback from teams
