Traceability System Context Diagram
Traceability is the ability to access any or all information about a product throughout its life cycle by using a system of recorded identifications. Traceability also relates to the ability to track and trace along the supply chain. A context diagram is a graphical representation of a system that must only use one process to represent the entire system and deliberately does not go into defining all the processes so as to prevent people from getting bogged down in complex details at an early stage. As the traceability system context diagram suggests, we use circles to represent the system in terms of a single process. There will never be more than a single process in any context diagram. We use a rectangle to represent any external entities affecting the system and arrows to represent the data flow.
