UGC-NET | UGC-NET CS 2017 Nov – III | Question 47

A simple stand – alone software utility is to be developed in ’C’ programming by a team of software experts for a computer running Linux and the overall size of this software is estimated to be 20,000 lines of code. Considering (a, b) = (2.4, 1.05) as multiplicative and exponention factor for the basic COCOMO effort estimation equation and (c, d) = (2.5, 0.38) as multiplicative and exponention factor for the basic COCOMO development time estimation equation, approximately how long does the software project take to complete ?
(A) 10.52 months
(B) 11.52 months
(C) 12.52 months
(D) 14.52 months


Answer: (B)

Explanation:
20,000LOC = 20KLOC
Effort = a*(KLOC)^b PM
T_{dev} = c*(Effort)^d Months
Effort = 2.4*(20)^{1.05} PM = 55.756 PM
T_{dev} = 2.5*(55.756)^{0.38} Months = 11.52 Months
