Function Points: size estimation Function Point
\end_layout
\begin_layout Standard
A function point is a "unit of measurement" representing how many functionalitie
s the information system provides to the user.
Function points are used to calculate a functional size measurement (FSM)
of software; usually the cost of a single unit is calculated from past
projects.
