All the processes carried out in most organizations are liable to be audited so that they allow more confidence in the organization itself and/or in its customers or users. Software is not an exception; in fact, one has become used to seeing audits in information technology departments. However, it is more unusual that audits should be implemented concerning software size measurement in function points by using the most common measurement techniques, such as the IFPUG (International Function Point User Group) ones. This association was formed in 1986 aimed at spreading and adapting the Function Point Measurement Method, which was invented by Allan Albrecht in 1979 (Albrecht, 1979) and published in 1984 in his well-known paper “Productivity Measurement and Estimate Validation”. Such software size measurement is being employed more and more in the software used as a counting element for other metrics like productivity (PF/Pers. Month), quality (defects /PF), cost (Euro /PF), etc. It is also essential to measure a number of variables when implementing an SPI (Software Process Improvement) in order to learn the current starting situation, and what situation one is in after the implementation of such a process.
