A Formal Definition of COSMIC-FFP for Automated Measurement of ROOM Specifications
H. Diab · 2001
We propose a forrealization 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 definition is general and can be applied to any specification language. We propose a forrealization of this definition for the ROOM language. ROOM is now widely used for constructing real-time systems. The benefits of our forrealization are twofold. First it eliminates measurement variance, because the COSMIC-FFP informal definition is subject to interpretation by COSMIC-FFP raters, which may lead to different measurements for the same specification, depending on the interpretation made by each rarer. Second it allows the automation of COSMIC-FFP measurement for ROOM specifications, which reduces measurement costs. Finally, the formal definition 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.
