AS/NZS ISO/IEC 20926:2022 identically adopts ISO/IEC 20926:2009, which specifies the set of definitions, rules and steps for applying the IFPUG (International Function Point Users Group) functional size measurement (FSM) method. It applies to all functional domains and is fully convertible to prior editions of IFPUG sizing methods.
