Notes:
-
It is a work product expressed in terms of functionality as seen by the user.
-
Count fields on windows, screens, reports.
-
Count the types of data being tracked and interfaced.
-
The adjustment factor takes things like performance, communication, technology, environment, and business rules into account.
-
I like function point counts because it gives you a constant, derivable number that everyone understands and can discuss. It removes some of the politics and variability inherent in estimating.
-
Convert the function point to hours based on the technology, tools, and experience.
-
It has problems.
-
On large systems it is time consuming.
-
It does not do conversions and technology upgrades well (e.g., Y2K or install a new version of Oracle).
-
Like any internal system documentation, it is difficult to maintain.
-
Still better than nothing!!
