The above formula is used for the cost estimation of the basic COCOMO model and also is used in the subsequent models. The constant values a$,$b$,$c$,$ and $d$ for the Basic Model for the different categories of the system:

The effort is measured in Person$-$Months and as evident from the formula is dependent on Kilo$-$Lines of code. The development time is measured in months. These formulas are used as such in the Basic Model

calculations

Calculate the effort $($E$),$ duration $($D$)$ and staffing $($S$)$ for given Kilo$-$Lines of code $($KLOC$)?$

a$)$ KLOC$=10,E=,D=,S=?$

b$)$ KLOC$=150,E=,D=,S=$

c$)$ KLOC$=500,E=?,D=?,S=?$
