20,000 LOC (Lines of Code) = 20K LOC (Given)
(a,b) = (2.4, 1.05) (Given)
(c,d) = (2.5,0.38) (Given)
The basic COCOMO model gives an approximate estimate of the project parameters. The basic COCOMO estimation model is given by the following expression:
Effort = a * (KLOC)b PM (PM = Person Months)
T dev = c * (Effort)d months (T dev = Development TIme )
Effort = 2.4 * (20)1.05 PM
= 2.4 * 23.231 = 55.756 PM
T dev = 2.5 * (55.756)0.38 months
= 2.5 * 4.608 = 11.52 months
Therefore, time taken for completion of the software project is 11.52 months
