Software engineering is that branch of
engineering where a software will be

developed using
well tested, well proved engineering

principles,
procedures and the respective methods.

So, that is the software engineering.

So, let us
discuss that how this software engineering

has been defined
by different persons and organizations.

So, if we consider Fridge Bauer, then
he has defined

the software
engineering in this particular format.

That is software engineering is the
establishment and use of sound engineering

principles, methods, tools that can be
used to produce high quality software that

is reliable and works efficiently on real
machines.

So, the software should be reliable,
should be meeting with the respective

users requirement and should run on the
real machines.

IEEE, they have declared and they have
defined the software engineering in this way.

The application of a systematic,
disciplined, quantifiable approach to the

development,
operation and maintenance of software,

that is the application of engineering
to the software.

That means they have given emphasis more
on the development process, there is

operations to be implemented, the
maintenance of the software during the

upgradation of the
software to execute some

change request as
requested by the client.

So, all those
things must be done on this respective

software product
and this software developed software.

And that is
why this IEEE, they have given more

emphasis on this
operations and maintenance of software.

And that is the application of engineering
to the software.

Let us understand what software
engineering stands for.

And here
we are having two terminologies, one

is the software and
the one is the engineering.

So, let us discuss them one by one.

So, what is the software?

A software is more than just a program
code.

A program is an executable code which
serves some computational purpose.

We know that whenever we write in a
program in some specific language,

then obviously it is having some purpose
and at the end the program should be

executed through the executable version of
the program.

A software is considered to be collection
of executable such programming codes,

libraries
and then associated libraries and then

documentation and
remark and documentation and so on.

So, what is the software product?

So, software is nothing but whenever a
particular software is executing that

means, it
is taking help of multiple executable

codes, the respective libraries and the
documentation.

Software when it is
made for a specific

requirement
will be known as a software product.

So, whenever a particular software will be
developed for a certain purpose only,

then it will be known as a software
product.

So, now let us consider the four phases
and we are having transformation one,

two and three to show
you that what are the

software development
process transformations.

So, first user needs and expectations are
to be gathered.

So, all the user needs, their respective
requirements, expectations are to be listed.

And then transformation one which is
having a name known

as analysis but the
problem statement will be developed.

Then in the transformation two that is
known as the design phase, in this case

this from the problem statement will be
going for the detailed design.

And in the transformation number 3,
that is the implementation phase where

this particular software designed,
this particular format will be implemented

as a software product.

So, these
are the different phases with the help

of which the transformations will take
place.

Now let us discuss engineering.

In the previous slide we discussed software,
now we will be discussing engineering.

Engineering on the other hand is all about
developing the products using well-defined

scientific principles and methods and
procedures.

So, that is known as the engineering.

So, let us go for the summary.

So, software engineering is an engineering
branch associated with the development of

software product using well-defined
scientific principles, methods and procedures.

The outcome of software engineering is an
efficient and reliable software So,

in this way, we have defined what is a
software engineering and we have given you

one overview of the software engineering
topic.
