Nice argument sir, but I have studied the subject too. Software maintenance has three parts Corrective, adaptive and perfective. Adaptive maintence take about 80% of all the maintanace cost and efforts, because the underlying platform on which the system runs keeps changing which is not quite the case of classical engineering deciplines.
Corrective maintenance is plain removal of bugs while perfective maintenance is the REAL IMPROVIZATION which is done by those who builds the software. Right? In this regard Brhma and Vishnu are the same.

or are they?? well yes you are right about the maintenance basics, but they are maintenance all the same.... within the seed of maintenance there is also creation, like the bit of proactive maintenance. and that is again something that indians are doing a great job of.
