Question

How is reuse catered for in the original COCOMO model?

a.

by adjusting the unadjusted value KLOC using a formula

b.

by considering the fractions of the system that require redesign, recoding, and re-integration

c.

by using a different set of cost drivers

d.

by using a different exponent in the effort equation

Posted under Software Engineering

Answer: (b).by considering the fractions of the system that require redesign, recoding, and re-integration Explanation:In the original COCOMO model, reuse is catered for by separately considering the fractions of the system that require redesign, recoding, and re-integration. An adjustment factor AAF is then given by the formula AAF = 0.4DM + 0.3CM + 0.3IM. An adjusted value AKLOC, given by AKLOC = KLOC * AAF/100 is next used in the COCOMO formulae, instead of the unadjusted value KLOC. This way, a lower cost estimate is obtained if part of the system is reused.
