A SW company with CMMI$=1$ is hired on a project where the project team gets along perfectly well, the company is totally familiar with the application, there is no client involvement, a very thorough risk analysis has been implemented.

a$)$ Given that $17$ attributes are considered in estimating the SW effort, what COCOMO II model is used to estimate the effort?

b$)$ Calculate the exponent term $B$ considering the first sentence of the question!

c$)$ At the end of the project, SW effort estimated, $E_{\text{e}\text{s}\text{t}},$ is found to be $20\%$ less than the actual effort, $E_{\text{a}\text{c}\text{t}},$ i$.$e$.,e_E=\{|E_{\text{a}\text{c}\text{t}}\}|)/(E_{\text{a}\text{c}\text{t}}^{**}.$ Given that $E=A**$ size ${?}^B**M$ and $M_{\text{e}\text{s}\text{t}}=0\mathrm{.}85M_{\text{a}\text{c}\text{t}},$ what is the percent error, $e_{\text{s}\text{i}\text{z}\text{e}\text{,}}$ in the SW size?

d$)$ What would be $e_{\text{s}\text{i}\text{z}\text{e}}$ if $M_{\text{e}\text{s}\text{t}}=0\mathrm{.}8M_{\text{a}\text{c}\text{t}}?$ What conclusions would you draw from such a result?

Hint: $e_E$ denotes the percent error in effort; A and $M$ denote, in respective order, the constant factor and the multiplier in the SW effort estimation formula.

Note that to get any points you have to show the correct calculations for both parts $($b$)$ and $($c$).$ No points for only correct results with no or incorrect calculations!!! PLEASE B PART SOLUT$$ON$.$
