Block Definition Diagram

A Block Definition Diagram (BDD) is a visual tool used in systems engineering to organize and represent the structure of a system. It shows the main components (blocks) and their relationships, like how a car has parts such as the engine, wheels, and chassis. Each block can have details about its functions and connections to other blocks. The diagram helps teams understand, design, and communicate the system's architecture clearly, ensuring everyone is on the same page about how parts fit and work together.
