Architecture versus Design

Rick Kazman and Amnon Eden's "Defining the Terms Architecture, Design, and Implementation" and "Architecture, Design and Implementation" provide a distinction based on Intension and Locality criteria.

Rick and Amnon argue that

• Architectural specifications are intensional and non-local
• Design specifications are intensional but local
• Implementation specifications are both extensional and local

They demonstrate that:

• Architectural styles are intensional and non-local
• Design patterns are intensional and local
• Implementations are extensional and local

A must read for architects and designers.
