Abstract: Functional Size Measurement (FSM) methods obtain the functional size of software systems by quantifying the Functional User Requirements (FUR). Since different FSM methods use distinct abstractions to depict a software system, a generalized model was proposed. According to the generalized abstraction of the software system, data groups and transactions involved in the measurement process were generalized at first. And then an example of IFPUG FPA was given in order to interpret the transformation and mapping of Function Point Analysis to the generalized model. Finally, the algorithm description of the measurement process was presented.
