Which of the following statements correctly reflect the role of UML in architectural description? Select ALL that apply.

A 2006 survey found that when UML was used for architecture, it was mostly applied in a loose and informal way

UML is most valuable when documenting an architecture in detail or using model-driven development

UML is universally agreed to be the best notation for all stages of architectural design

For architectural design, informal notations on a whiteboard are often preferred during the design process itself

UML was designed primarily for describing object-oriented systems and works best at the implementation level

Correct Answer

(1) UML was designed primarily for describing object-oriented systems and works best at the implementation level

(2) A 2006 survey found that when UML was used for architecture, it was mostly applied in a loose and informal way

(3) UML is most valuable when documenting an architecture in detail or using model-driven development

(4) For architectural design, informal notations on a whiteboard are often preferred during the design process itself

Explanation

UML was designed for object-oriented systems; at the architectural level, object classes are often too close to the implementation to be useful. A 2006 survey confirmed UML was used informally for architecture. UML is most valuable for detailed documentation or model-driven development. During the design process itself, informal notations are often quicker and clearer.
