Why Is Architecture Important?

Architecture represents foundational design decisions– Hardest to change later on– Most critical to get right up front

Architecture serves as a foundation for the capture of intellectual property– Code– Business rules/domain expertise

A vehicle for communication– Sponsors– Developers– Project Managers– Documenters– Customers

The blueprint for a successful software application

What is a “Reference Architecture”?

Taken at literal value –– “Architecture”: The structure of an application

– “Reference”: Intended to provide guidance Reference Architectures are for knowledge

transfer and learning– Applications/code

– Documents

– Diagrams Describing and demonstrating best practices for

software application development

Guidance for success
