Welcome to COSMIC-Sizing

The open, ISO standard sizing methodology for software

The COSMIC Functional Sizing Standard is an open method for robust software size measurement. It is based on fundamental software principles and so is suited to all types of software. The method was developed by a team of experts and builds on the original functional size measurement methodologies: IFPUG and Mark II Function Points. The COSMIC Sizing methodology became an ISO standard in 2003.

The term COSMIC is an acronym for the Common Software Measurement International Consortium, the not for profit organisation that governs the standard and certifications.
