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 usual meanings. The basic $$COCOMO$$ equations are of the form

Consider a software project with the following information domain characteristics for calculation of function point metric.

Number of external inputs $$\left( {\rm I} \right) = 30$$
Number of external outputs $$\left( O \right) = 60$$
Number of external inquiries $$\left( E \right) = 23$$
Number of files $$(F) = 08$$
Number of external interfaces $$(N) = 02$$

It is given that the complexity weighting factors for $$I, O, E, F$$ and $$N$$ are $$4, 5, 4, 10$$ and $$7,$$ respectively. It is also given that, out of fourteen value adjustment factors that influence the development effort, four factors are not applicable, each of the other four factors have value $$3,$$ and each of the remaining factors have value $$4.$ The computed value of function point metric is _____________.

Consider a software program that is artificially seeded with $$100$$ faults. While testing this program, $$159$$ faults are detected, out of which $$75$$ faults are from those artificially seeded faults. Assuming that both real and seeded faults are of same nature and have same distribution, the estimated number of undetected real faults is ____________.

$$a)$$ Specifications can be developed incrementally
$$b)$$ Requirements compromises are inevitable
$$c)$$ Explicit recognition of risk
$$d)$$ Inflexible partitioning of the project into
