Defines a class of acceptable solutions |
Defines a single specific solution |
|
About suitability or fitness for purpose, as defined by the mission |
About engineering optimization, within architectural constraints |
|
Role of the architect is mostly to make correct inferences about the mission, solution and environment |
Role of the designer is mostly to make correct decisions about the solution |
|
Architecture is done by architects |
Design is done by developers |

Primary audience is mission and solution stakeholders, which usually includes designers and implementers |
Primary audience is solution implementers |
