What Is Enterprise Architecture and Why It Matters

For many people, even seasoned IT professionals, "enterprise architecture" is an unfamiliar term. "Architecture" is an abstraction of solutions to a class of common problems, a concept well known in IT discussions.

Enterprise architecture is important, leading us to ask: what is enterprise architecture?

Just as we are familiar with software architecture, we can imagine an enterprise composed of people and departments as a massive software system; the architecture of this massive software is called enterprise architecture.

Enterprise architecture plays a crucial role in information system construction and digital transformation, yet there are gaps in domestic practice. The high discussion threshold stems from many people never having heard the term and lacking a clear concept.

Why do we need enterprise architecture? The answer is the same as why software needs architecture: early development was ad‑hoc and handcrafted, which cannot meet modern demands for engineered, industrialized software.
