Whenever a software will get delivered,
then after also, some modifications,

some additions might be required.

So, let us discuss more on this software
maintenance.

So, software maintenance is widely
accepted part of SDLC nowadays.

And it stands
for all the modifications and updations

done after
the delivery of the software product.

And there are
number of reasons why modifications

are required and
some of them we have listed below.

So, let us go for the respective causes.

So, the first one we are considering is a
market condition.

So, policies which changes over the time
such as taxation, newly introduced

constraints, like how to maintain
bookkeeping, main trigger, may trigger

need for the different modifications.

So, that is why due to the change in the
government policy, due to the change in

the market conditions, the maintenance
might be required.

Next one is our client's requirement.

So, over the time, the customer may ask
for new features or functions in the

system to get implemented and
incorporated.

In that cases also, the software
maintenance will be required.

So, next one we are going for host
modifications.

So, if any one of the hardware and or the
platform, platform means actually the

hardware and the operating system
collectively we usually call it as a platform.

So, if any of the hardware and or the
platform such as the operating system of

the target host changes, the software
changes are needed to keep the

adaptability and that is why the
maintenance will be required.

So, there is some change in the hardware,
there is some change in the operating

system, there is some change in the
respective drivers.

So, in those Most cases, the software
maintenance might be required.

Next one is the organizational changes.

So, organization changes.

So, if there is any business level change
at the client end, such as the deduction

of the organization strength, acquiring
another company, organization venturing

into some new business, need to modify in
the original software may arise.

So, sometimes the company may be growing,
sometimes a company may be shrinking,

sometimes a
company may be opening a new wing in

which business they
were not there previously.

So, due to some reasons, the organization
changes will be there and for that,

this software changes will be some changes
in the software will be required and that

is why the maintenance will be also very
much necessary there.
