An enterprise architecture's ability to respond to changes degrades during its useful life. Degradation occurs when the existing architecture is not ideal and changes over time stretch the architecture. The result of degradation is called "accidental architecture," and it happens when the architectural model evolves based on a series of tactical decisions instead of a strategic plan.
You can reduce the impact of software changes over time by keeping track of the architecture. You can examine the dependencies among the architecture's various parts, and use rules to specify the dependencies that are allowed and disallowed. This prevents your architecture from degrading accidentally, which makes architectural evolution explicit and helps manage its complexity.
Neeraj Sangal describes architectural dependencies and how they can influence the long-term reliability and extensibility of your enterprise architecture. He focuses on tracking dependencies among parts of the architecture using the Design Structure Matrix (DSM). You'll learn about the value of managing dependencies among architectural components and how dependency tracking can keep your architecture relevant and flexible over time.
