IT Architecture vs. Design
Both talk about specification, but to different degrees: Architecture specification is more abstract and can be implemented in more than one way
Design is more concrete and requires to proceed to implementation
Architecture addresses alignment, construction, deployment, operational and retirement aspects of solution; Design often is just about construction
