A FunctionPointEstimate uses a combination parameters and complexity factors to compute an estimated number of function points for the system.
Since the estimation follows the algorithme described in general available litterature it will not be described in details here.
In addition to the fields of the main tab the window contains tabs for ‘External Input’, ‘External Output’, ‘Inquiries’, External Data’ and ‘Internal Data’ are used.
The user is supposed to enter values for the number of ‘Simple’, ‘Average’ and ‘Complex’ parameters. In the buttom row of the dialogs the company standards can be entered.
The subdialog ‘Complexityfactors’ gives a list of factors – each with a scale of importance ranging from 1 to 6.
When all parameters are set up, the compute button can be pressed.
The properties of a FunctionPointEstimate are:
