Previsioni a partire dai function point

In un intervento sulla mailing list requirements-engineering, Capers Jones, un'autorità nelle statistiche relative allo sviluppo software, ha fornito queste indicazioni:

"Function point size raised to the 0.4 power gives a useful prediction of
development schedules in calendar months. (Agile projects should use the 0.34
power).

Function point size raised to the 1.25 power gives a useful and alarming
prediction of the probable number of bugs that will be encountered.

Function point size raised to the 1.2 power predicts numbers of test cases
needed.

Function point size divided by 150 predicts development team size."
