·         shapes and describes a solution, usually at a project level

·         responsible for the quality and completeness of a solution outline or high-level design.

·         describes architecture at a level sufficient for detailed design and building to proceed

·         must understand all facets of design well enough to form a coherent solution architecture

·         must partnership with and coordinate lead business analysts, software architects and others

·         is responsible for delivery quality: focuses on critical success factors, especially non-functional qualities.
