FP = Count total x [0.65 + 0.01 x Σ(Fi
)]
Where
Count total = Summation of number of
external inputs (EIs), number of external
outputs (EOs), number of external inquiries
(EQs), number of internal logical files (ILFs),
and number of external interface files (EIFs).
Fi
(i 1 to 14) = value adjustment factors (VAF)
based on responses to the 14 questions.
