This work has presented a sequence of steps where a
functional sizing metric (i.e. UCP) was used to support not
only the planning processes but also the monitoring and
controlling processes. A tool has been developed in order to
demonstrate that the sequence of steps can be automated
and provide an easier usage of the technique. Three
techniques were considered: the Use Case Points,
COCOMO II and EVA. It was shown that through
functional sizing metric it is possible to calculate the effort
and the development costs, providing the inputs to planning
and control processes of the software project.
