Consider the basic COCOMO model where E is the effort applied in person-months, D is the development time in chronological months, KLOC is the estimated number of delivered lines of code (in thousands) and ab, bb, cb, db have their usual meanings. The basic COCOMO equations are of the form

A

E = a<sub>b</sub> (KLOC) exp(b<sub>b</sub>), D = c<sub>b</sub> (E) exp(d<sub>b</sub>)

B

D = a<sub>b</sub> (KLOC) exp(b<sub>b</sub>), E = c<sub>b</sub> (D) exp(d<sub>b</sub>)

C

E = a<sub>b</sub> exp(b<sub>b</sub>), D = c<sub>b</sub> (KLOC) exp(d<sub>b</sub>)

D

E = a<sub>b</sub> exp(d<sub>b</sub>), D = c<sub>b</sub> (KLOC) exp(b<sub>b</sub>)

BASIC COCOMO:

It is the simplest version of the COCOMO model which uses only LOC (line of code) as an input matrix to predict the cost, time and team size.

In BASIC COCOMO,

Development effort(E) = a_b (KLOC) exp(b_b)

where KLOC is the size of the program in lines of code.

Development time (D) = c_b (E) exp(d_b)

Team size = (development effort) / (development time)
