Architecture

“Activity concerned with global design constraints, such as

programming paradigms,architectural styles, component-based software engineering standards, design principles, and law-governed regularities.”

The Agile Architecture’s primary objective is to facilitate a working 

solution to a changing need in thecontext of an Agile method.

That is, without a Big Up-Front Design phase before development.
