The Operational Context Diagram: How It Complements the System Context Diagram, and Helps You Design Technical Aspects of a System

For many years, application architects and analysts have used the System Context Diagram (SCD) as a powerful tool to share the high-level view of a system. The SCD provides only a functional view of the system, a view that later leads to the use case model. To completely specify the system under development, non-functional requirements must be taken into account. NFRs create another view of the system context: the operational context diagram, which then segues to the operational model. In this paper, learn about a technique to complement the SCD with a non-functional oriented operational context diagram.
