A software company is planning to develop a software system with three main components:

Database component:

Size ${?}_{(})=30$ KDSI

$\frac{?}{\text{b}\text{a}\text{r}}(EAF)=0\mathrm{.}85$

Graphical user interface component:

Size $=10$ KDSI

Accounting policies and rules component:

Size ${?}_{(})=50$KDSI

$EA{F}_{{?}_{?}}=0\mathrm{.}95$

Using the COCOMO II level, answer the following questions:

$1-$What is the total size of the project?

$2-$What is the mode of the project?

$3-$What is the value of EAF $($Effort Adjustment Factor$)?$

$4-$What is the effort required for the whole project?

$5-$What is the development time for the project?

$6-$What is the average staffing required for the project? $?$

$7-$Calculate the adjusted effort, and development time for each component. $?$
