This work product describes the elements that will make up the implemented system. It communicates abstractions of particular portions of the implementation.

While architecture focuses on interfaces, patterns, and key decisions, the design fleshes out the technical details in readiness for implementation, or as part of implementation.

This product can describe multiple static and dynamic views of the system for examination. Although various views may focus on divergent, seemingly independent issues of how the system will be put together and work, they should fit together without contradiction.
