}}

The International Function Point Users Group (IFPUG) is a US-based organization with worldwide chapters of Function point analysis metric software users. It is a non-profit, member-governed organization founded in 1986.

IFPUG owns Function Point Analysis (FPA) as defined in ISO 20296 which specifies the definitions, rules and steps for applying the IFPUG's functional size measurement (FSM) method. FPA can be traced to the work of Allan Albrecht of IBM who pioneered functional sizing in 1979 which derived a functional size of product value distinct and disassociated from lines of code, technology, or software language.
