Enterprise IT Architecture

The design and description of an enterprise’s entire set of Information Technology (IT) and Operational Technology (OT). This includes how both IT and OT are configured and integrated, and how they interface to the external environment at the enterprise’s boundary. It also includes protocols for how they are operated to support the enterprise strategic mission, and how they contribute to the enterprise’s overall security posture.

It is important to note that Enterprise Architecture and Power Systems Architecture are complementary but different. As the names suggest, the former is focused on the IT and OT environment within an enterprise while the latter focuses on the overlaid Network of Structures which constitute the end-to-end Power System.
