A **context diagram** is a simple representation that treats the system of interest as a [[Black Box]], instead focusing on how it interacts with its environment. # Examples - [[IDEF0]] has the "A minus One" diagram, which shows ICOM lines for the function as a whole - [[C4 Model]]'s first "C" stands for "*context*" - I'd argue that [[Use Case Diagrams]] are a form of context diagram **** # More - [[Diagram Types (index)]] ## Source - Various over the years
