This document defines function point analysis and provides an example calculation. Function point analysis is a method to estimate the size and scope of a software project by defining its required functions and complexity. The example calculates the function points for a project with 32 external inputs, 60 external outputs, 24 external inquiries, 8 internal logical files, and 2 external interface files, using the standard function point calculation formula and average complexity adjustment values. The total function points calculated for this example project is 661.26.

ANALYSIS

3. Definition
It is a process which defines
the required functions and
their complexity in a piece of
software in order to estimate
the software's size and
scope upon completion.

5. Function Point
Calculation
Example 1. Compute the function point value
for a project with the following information
domain characteristics:
(1) No. of external inputs = 32
(2) No. of external outputs = 60
(3) No. of external inquiries = 24
(4) No. of internal logical files = 8
(5) No. of external interfaces = 2
Assume all complexity adjustment values are
average. Consider weighing factor as:

6. Function Point
Calculation
Solution :
Now, Fi for average case = 3.
So sum of all Fi ( i <- 1 to 14 ) = 14 × 3 = 42
Count Total = 32×4 + 60×5 + 24×4 + 8×10 + 2×7
= 618
FP = Count Total × [0.65 + 0.01 × ∑ (Fi ) ]
= 618 × [0.65 + 0.01 × 42]
= 618 × [0.65 + 0.42]
= 618 × 1.07
= 661.26
