What kind of models does an Enterprise Architecture describe?

What is an Enterprise Architecture Model?

Many mistakenly assume that Enterprise Architecture is a “tech thing” only. This could not be further from the truth.

From a modeling perspective, enterprise architecture brings great clarity to a system.

What is a system? According to Google: “A set of connected things or parts forming a complex whole, in particular.” Note: No use of the word technology in the definition.

What kind of models does an Enterprise Architecture describe? Again, according to Google (define keyword): “An enterprise architecture (EA) describes the structure of an enterprise, its decomposition into subsystems, the relationships between the subsystems, the relationships with the external environment, the terminology to use, and the guiding principles for the design and evolution of an enterprise …”. Note: No use of the word technology in the definition.

Or to summarize, Enterprise Architecture is the System of the Enterprise

A subset of an enterprise architecture are automated systems. Another subset of an enterprise architecture are NOT automated systems.

Let’s take the US Government as an example. The US government is composed of 3 branches – executive, legislative, and judicial. All 3 branches work together in a SYSTEM to provide life, liberty, and the pursuit of happiness. An Enterprise Architecture is used to describe the system of the US Government.

Every business, government agency, university etc… has an enterprise architecture. The question is – are they fully conscious of their enterprise architecture? Furthermore, what are the benefits of being fully conscious of an enterprise architecture? What are the benefits of using an Enterprise Architecture? With those questions in mind, stay tuned for my next blog post.

Hint: the value of adding the TIME dimension to our enterprise architecture models to effectively manage change.
