Que : 1 . The Software Maturity Index (SMI) is defined as
SMI = [Mf – (Fa + Fc + Fd)] / Mf
Where
Mf = the number of modules in the current release.
Fa = the number of modules in the current release that have been added.
Fc = the number of modules in the current release that have been changed.
Fd = the number of modules in the current release that have been deleted.
The product begins to stabilize when


1. SMI approaches 1
2. SMI approaches 0
3. SMI approaches -1
4. None of the above
Please Select Ans Options .
Explanation

Explanation:
SMI = (M – (A + C + D)) / M
SMI = 1 – N/M, where M is the total number of modules in the current version of the system and N is the number of modules added, changed or deleted between the previous version and this one.
SMI can be a measurement of product stability, when SMI approaches 1.0 the product is stable. When correlated with the time it takes to complete a version of the software, you have an indication of the maintenance effort needed.
