GATE | GATE-IT-2004 | Question 17

In a software project, COCOMO (Constructive Cost Model) is used to estimate
(A) effort and duration based on the size of the software
(B) size and duration based on the effort of the software
(C) effort and cost based on the duration of the software
(D) size, effort and duration based on the cost of the software

Answer: (A)
Explanation: The basic COCOMO equations take the form

Effort Applied (E) = a_b(KLOC)^b_b[ person-months ]

Development Time (D) = c_b(Effort Applied)^d_b[months]

People required (P) = Effort Applied / Development Time [count]                                        //Source:Wikipedia

As it can be observed from above equations,Effort and Duration are on L.H.S whereas KLOC(Line of code) ,used to measure program size is on R.H.S. Hence, Answer is A
