UGC NET CSE | December 2018 | Part 2 | Question: 57

Question

A legacy software system has $940$ modules. The latest release required that $90$ of these modules be changed. In addition, $40$ new modules were added and $12$ old modules were removed. Compute the software maturity index for the system.

• A. $0.849$
• B. $0.524$
• C. $0.725$
• D. $0.923$

Answer 1

Ans A

SMI = Mt – ( Fa + Fc + Fd)/Mt, Where

SMI – is the Software Maturity Index value

Mt – is the number of software functions/modules in the current release

Fc – is the number of functions/modules that contain changes from the previous release

Fa – is the number of functions/modules that contain additions to the previous release

Fd – is the number of functions/modules that are deleted from the previous release.

SMI =(940 - (40 + 90 + 12 )) /940

        =0.8489

        =0.849

@mahesh13 Answer is absolutely correct, hence upvoted. But tell me one thing, why u subtract 40 new modules which were added ? Means what is the sense of subtracting it ?
