Yes, there are three others standard methods of functional measurement:

NESMA — The association of metrics from Netherlands has its own counting manual, currently at version 2.0, whose the first version in 1990 was based on IFPUG manual. It uses the same philosophy, concepts, terms and rules of IFPUG, with some different GUIDELINES. The measurement of a development project or an application produces results very similar under both approaches – IFPUG and NESMA. However, both organizations have different approaches to function POINT analysis application in software improvement projects.

MARK II — was created by Charles Symons in the mid80s. Its spread has been hampered initially because the method was owned by KPMG consultant for several years. Today is a public domain metrics method MAINTAINED by the UK Association of Metrics —UKSMA. It’s a method wich its application is restricted to the UK.

COSMIC — In 1997 a group of researchers from the University of Quebec developed a new method for measuring functional realtime systems, called Full Function Points (FFP). In 1998 a group of EXPERTS in software measurement constituted the COSMIC (Common Software Measurement International Consortium) in order to develop a new method of measuring functional size based on the best features of existing methods and incorporating new ideas. This new method proposed in 2000, called COSMICFFP, in practice was a refinement of the FFP method. It is not a technique as widespread as the IFPUG, but there is much research being conducted on this method.
