Q18,p3,j14. Consider a project with the following functional units :

Number of user inputs = 50

Number of user outputs = 40

Number of user enquiries = 35

Number of user files = 06

Number of external interfaces = 04

Assuming all complexity adjustment

factors and weighing factors as

average, the function points for the

project will be

(A) 135 (B) 722

(C) 675 (D) 672

Function Point calculation

 A function point is a rough estimate of a unit of delivered functionality of a software project. Function points (FP) measure size in terms of the amount of functionality in a system. Function points are computed by first calculating an unadjusted function point count (UFC). Counts are made for the following categories

• Number of user inputs

• Number of user outputs

• Number of user inquiries

• Number of files

• Number of external interfaces

TABLE  Function point complexity weights.

Measurement parameter	Weighting factor
	Simple	Average	Complex
Number of user inputs	3	4	6
Number of user outputs	4	5	7
Number of user inquiries	3	4	6
Number of files	7	10	15
Number of external interfaces	5	7	10

Each count is multiplied by its corresponding complexity weight and the results are summed to provide the UFC. The adjusted function point count (FP) is calculated by multiplying the UFC by a technical complexity factor (TCF) also referred to as Value Adjustment Factor (VAF).

Final Adjusted FP = UFC x VAF.
