Solution vision + solution context. Captures the big-picture view of the whole solution, with the basis for analyses and trade-off studies.

1–1. Business Process Graphic:

Provides a mission perspective of the solution’s core capabilities to guide design, development, and validation of the solution, and to ensure that the solution satisfies its mission needs. In addition, it provides a functional perspective of the solution’s business activities, enabling management to use the Solution Architecture to identify enhancements to operations.
