CHARACTERISTICS OF THE FSM METHODS

The following mandatory characteristics of the FSM methods are listed in the standard ISO 14143-1:2007(E) [1].

A FSM method is:

  • independent of the methods used to develop the software being measured;
  • independent of the methods used to support the software being measured;
  • independent of the technological components of the software being measured.

This implies that functional size is not:

  • derived from the effort required to develop the software being measured;
  • derived from the effort required to support the software being measured;
