It may consist of elements produced by several organizations and integrated by one. • Subsystem - A functional grouping of components that combine to perform a major function within an element. • Assembly - A functional subdivision of a subsystem and generally a self-contained combination of items performing a function necessary for subsystem operation. A functional unit viewed as an entity for purpose of analysis, manufacturing, testing, or record keeping. • Part - An element that is not normally subject to further subdivision or disassembly without destruction of designated use.
