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 $a_b, b_b, c_b, d_b$ have their useful meanings. The basic COCOMO equations are of the form

  1. $E=a_b (KLOC) exp(b_b), D=c_b(E) exp(d_b)$
  2. $D=a_b (KLOC) exp(b_b), E=c_b(D) exp(d_b)$
  3. $E=a_b exp(b_b), D=c_b (KLOC) exp(d_b)$
  4. $E=a_b exp(d_b), D=c_b (KLOC) exp(b_b)$

Answer: A

In basic COCOMO model,

Effort Applied, E = a*(KLOC)b
Development Time, D = c*Ed
People Required, P = E/D

where KLOC = Estimated number of delivered lines in thousands and a,b,c,d depends upon the software being Organic, Semi detached or Embedded.

COCOMO Model stands for Constructive Cost Estimation Model widely used in software engineering. 

If E is the effort applied in person-months, is the development time in chronological months, KLOC is the estimated number of delivered lines of code (in thousands) and ab,bb,cb,dhave their useful meanings. The basic COCOMO equations are of the form

=ab(KLOC)exp(bb)D=cb(E)exp(db)
