Top-Level Network Model

 A top-level workflow that describes the core activities needed to distribute an emergency alert using the WEA service. The workflow provides the anchor for the subsequent security risk analysis. After we develop a workflow model, we then determine which technologies support that workflow. 

 

 

The systems that support the WEA workflow are shown in Figure 6. In essence, the collection of systems in Figure 6 depicts the WEA system of systems. These systems support the end-to end WEA workflow and are the starting point for a deep dive into an analysis of WEA support technologies

Operation Workflows Sheet:

A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization
of resources into processes that transform materials, provide services, or process information.
It can be depicted as a sequence of operations, the work of a person or group,[2] the work of an organization
of staff, or one or more simple or complex mechanisms. (Wikipedia)
