Question 51

A company needs to develop digital signal processing software for one of its newest inventions. The software is expected to have 40000 lines of code. The company needs to determine the effort in personmonths needed to develop this software using the basic COCOMO model. The multiplicative factor for this model is given as 2.8 for the software development on embedded systems, while the exponentiation factor is given as 1.20. What is the estimated effort in personmonths?
234.25


932.50


287.80


122.40

Question 51 Explanation:
The Constructive Cost Model (COCOMO) is an algorithmic software cost estimation model developed by Barry Boehm. The model uses a basic regression formula, with parameters that are derived from historical project data and current project characteristics
In the Constructive Cost Model (COCOMO), following is formula for effort applied
Effort Applied (E) = a_{b}(KLOC)^{b} [ personmonths ]
= 2.8 x(40)1.20
= 2.8 x 83.65
= 234.25
In the Constructive Cost Model (COCOMO), following is formula for effort applied
Effort Applied (E) = a_{b}(KLOC)^{b} [ personmonths ]
= 2.8 x(40)1.20
= 2.8 x 83.65
= 234.25
Correct Answer: A
