description: Viewpoints for the EA on a Page framework. Each viewpoint specifies the artifact types it includes, the stakeholders it targets, and the purpose it serves. Derived from the CSVLOD artifact taxonomy and the three core EA processes described by Kotusev. EA on a Page does not formally define viewpoints, but its artifact types and processes imply a natural set of viewpoints that practitioners use in practice. These viewpoints formalize those implicit conventions.
