function point analysis การใช้

The function point analysis sizing standard is supported by the International Function Point Users Group ( IFPUG ).
The "'International Function Point Users Group IFPUG "'is a US-based worldwide organization of Function point analysis metric software users.
IFPUG owns Function Point Analysis ( FPA ) as defined in ISO standard 20296 : 2009 which specifies the definitions, rules and steps for applying the IFPUG's functional size measurement ( FSM ) method.
Since the inception of Function Point Analysis, several variations have evolved and the family of functional sizing techniques has broadened to include such sizing measures as COSMIC, NESMA, Use Case Points, FP Lite, Early and Quick FPs, and most recently Story Points.
