Question 186

The number of function points of a proposed system is calculated as 500. Suppose that the system is planned to be developed in Java and the LOC/FP ratio of Java is 50. Estimate the effort (E) required to complete the project using the effort formula of basic COCOMO given below :

E = a(KLOC)^b

Assume that the values of a and b are 2.5 and 1.0 respectively.

A	25 person months
B	75 person months
C	62.5 person months
D	72.5 person months

Question 186 Explanation:

Given data,

— Functional points(FP)= 500

— Lines of code(LOC) / FP = 50

— Effort(E) = a(KLOC)^b

— a = 2.5 and b = 1.0

— KLOC=?

Step-1: Find out KLOC

KLOC= ((LOC / FP)*FP)/1000

= 25

Where K=1000

Step-2: Find out Effort(E)= 2.5(25)^1.0

= 62.5 person months.

Correct Answer: C
