Block Definition Diagram (BDD)

A Block Definition Diagram (BDD) is a visual tool used in systems engineering to represent the structure of a complex system. It shows the different parts or components (called blocks) and how they relate to each other, such as which parts are contained within others or how they connect. Think of it like a detailed organizational chart that helps engineers understand and communicate the system’s architecture clearly. BDDs are essential for designing, analyzing, and ensuring all parts work together as intended in large or complex projects.
