ISO transposition and clarifications of the COSMIC-FFP method of functional sizing
Alain Abran, P. Fagg, Roberto Meli, Charles R. Symons · 2002
This paper describes and explains a few significant changes which have been made to the COSMIC FFP method of functional sizing of software targeted to be published in the Measurement Manual Version 2.2 (October 2002) and in the draft ISO/IEC 19761standard version of the method. These changes have been made to help understanding and consistent use of the method. None of the changes alter the principles of the method. These have never needed to be changed since the method was first defined, and have been confirmed by successful practical use in may organisations on different types of software. All the changes have arisen because it was found either that certain terms and definitions could be misunderstood and needed clarification, or because of the need to ensure consistency with existing ISO/IEC standard terminology and definitions (a design goal of the COSMIC FFP method).
