GATE 2015 CS (CS2) – Question 29
In basic COCOMO, E is person-month effort, D chronological development months, KLOC thousands of delivered lines, and $a_b,b_b,c_b,d_b$ are model parameters. Which equations apply?

Show answer and explanation
Correct answer: (A) $E=a_b(KLOC)^{b_b},\ D=c_bE^{d_b}$
Explanation
The basic model first estimates effort as a power of code size: E=a_b×KLOC raised to b_b. Development time is then a separate power of effort: D=c_b×E raised to d_b. These are A. The coefficients depend on the development mode; this historical topic is Software Engineering.
