Notes on the Example

This example, similar to other roadmap viewpoints in NAFv4, is how to model the scenario and is important for the understanding of the evolution of the architecture over time and its impact on decisioning. However, the specific representation of the roadmap for the benefit of non -architectural stakeholder readership should be as described in the content of the ‘Representation’ section of this viewpoint definition.
