A Formal Definition of Cosmic-ffp for Automated Measurement of Room Specifications
نویسنده
چکیده
We propose a formalization of the COSMIC Full Function Point (COSMIC-FFP) measure for the Real-time Object Oriented Modeling (ROOM) language. COSMIC-FFP is a measure of functional size. It has been proposed by the COSMIC group as an adaptation of the function point measure for real-time systems. The COSMIC-FFP de nition is general and can be applied to any speci cation language. We propose a formalization of this de nition for the ROOM language. ROOM is now widely used for constructing real-time systems. The bene ts of our formalization are twofold. First it eliminates measurement variance, because the COSMIC-FFP informal de nition is subject to interpretation by COSMIC-FFP raters, which may lead to di erent measurements for the same speci cation, depending on the interpretation made by each rater. Second it allows the automation of COSMIC-FFP measurement for ROOM speci cations, which reduces measurement costs. Finally, the formal de nition of COSMIC-FFP can provide a clear and unambiguous characterization of COSMIC-FFP concepts which is helpful for COSMIC-FFP measurement for other object-oriented notations like UML.
