Event-driven architectures (EDAs) are powerful—but they quickly become complex and hard to govern.
As domains, services, and messages grow, so does the challenge of understanding, documenting, and communicating what’s happening across the system.

Without proper documentation, an EDA can become a black box, leaving teams struggling to keep up.
