Need of software engineering.

So, question is coming in mind what is the
need of software engineering?

So, let us discuss on this aspect.

The need of software engineering arises
because of the higher rate of change in

user requirements and the environment on
which the software is working.

So, we know
that the change requests, the changes

will be demanded
on the existing software.

And that change may be due to the change
in the clients and users requirement or

due to the change in the environment on
which the software is working.

So, following are the some of the needs
stated.

So, first one is the large software.

It is easier to build a wall than a house
or building.

So, likewise as the size of the software
becomes large, engineering has to step to

give it a scientific process, so that we
can develop that large software.

The large software means it can be considered
as a collection of multiple modules.

So, we can develop multiple modules
and later we can

integrate them and we can get
the shape of the large software.

So, in this way there are different
processes in which we can develop the

large softwares and those processes will
be suggested by this software.

Next one is the scalability.

So, if the software process were not based
on scientific and engineering concepts,

it would be easier to recreate a new
software than to scale an existing one.

So, whenever the change requests will be
coming, then obviously we will be carrying

out those
changes, we shall implement those

changes in
the existing version of the software.

It is not like that, we shall go for a new
creation of another software, which will

be beyond our budget and beyond our
deadline.

So, that is why, so this particular
software process must have this scientific

and engineering concepts, so that we can
reflect new changes in the existing one.

So, dynamic nature, always growing and
adapting nature of the software usually

depends upon the environment in which the
user works.

If the nature of the software is always
changing, new enhancement need to be done

in the existing one
and this is where the

software engineering
plays a good and vital role.

So, always whenever a software is having a
version say 1.0 after a couple of months,

after a couple of days or say after a
couple of weeks, that

new recommends
will be originated, will be originating.

So, as a result of that, we will be going
for the next version of the same software.

And those implementation of the new
changes in the

software is depicting the dynamic nature
of the software.

So, quality
management, the better process of software

development provides
better and quality software product.

So, whenever we are implementing this
software engineering, this engineering

concept onto this software development
processes, then obviously, we can ensure

that our software will be with the better
and good quality, which was expected from

the client side and user side.

So, in this way, we have described,
we have discussed what are the needs of

software engineering in the development
process of a software.
