Software engineering -- IFPUG 4.1 Unadjusted functional size measurement method -- Counting practices manual
This standard has been revised by ISO/IEC 20926:2009
ISO/IEC 20926:2003 specifies the International Function Point Users Group (IFPUG) Release 4.1 unadjusted Functional Size Measurement Method.
It provides:a clear and detailed description of function point counting;
- a foundation to ensure that counts are consistent;
- guidance to allow function point counting of Functional User Requirements from the deliverables of popular software development methodologies and techniques;
- a framework to enable automated support for function point counting.
The provisions of ISO/IEC 20926:2003 can be applied by anyone using function point analysis for software measurement. ISO/IEC 20926:2003 was designed for use by persons new to function point counting as well as those with intermediate and advanced experience.
