| Question 3 |
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 ?

Question 3 Explanation:
Given data,
— lines of code(LOC)= 20,000 (or 20K)
— Multiplicative value ‘a’=2.4
— Exponential ‘b’=1.05
— Basic COCOMO formula= a*(LOC in K)b
— Multiplicative value ‘c’=2.5
— Exponential ‘d’=0.38
— Development=c*(basic COCOMO result)d
Step-1: Basic COCOMO formula= a*(LOC in K)b
= 2.4*(20)1.05
= 55.756
Step-2: Development= c*(basic COCOMO result)d
= 2.5(55.756)0.38
= 11.52 months
— lines of code(LOC)= 20,000 (or 20K)
— Multiplicative value ‘a’=2.4
— Exponential ‘b’=1.05
— Basic COCOMO formula= a*(LOC in K)b
— Multiplicative value ‘c’=2.5
— Exponential ‘d’=0.38
— Development=c*(basic COCOMO result)d
Step-1: Basic COCOMO formula= a*(LOC in K)b
= 2.4*(20)1.05
= 55.756
Step-2: Development= c*(basic COCOMO result)d
= 2.5(55.756)0.38
= 11.52 months
Correct Answer: B
