Function points are still a frequently used technique for estimating project size. The FPA method can be applied to both object oriented projects and projects where structured techniques are used. However for object oriented projects additional guidelines are needed. In the paper, these guidelines are described together with a simple example of their use with Unified Modeling Language (UML) notation. Counting Function points on real projects needs appropriate tool support. A prototype of such a tool, written in Java programming language, is presented in the paper. Its integration with the industry leading CASE tool has been made using XML Metadata Interchange (XMI) format. We also made tests on sample projects to prove both the method and the tool. The results can be found in this paper.
