We are discussing Software Quality
Attributes.

So, what are the different
attributes which will

decide whether
this software is a good quality or not?

So, let us discuss all these attributes
into further details.

So, first one we are going to consider
that is our architecture.

So, it is the key property of software
system.

So, it describes the internal structure of
the software system.

A good simple structure makes the system
easy to understand, change, test,

implement, maintenance, upgradations.

So, everything will
be simple if you select the

right architecture for
the right software domain.

Next one is the correctness.

A software product
satisfies given needs, also

it is free from errors
and should be reliable.

So, let us suppose a client is demanding
one software for some data processing,

say for some
numerical analysis oriented problems, where

he or she is requiring precision up to
10 decimal places.

So, the precision of our output must be
accurate to that 10 decimal places.

So, the correctness and the reliability of
the software should be up to that mark.

Ease of use, it should be easy to learn
and use.

If you can make your software user
friendly, the software will be more

popular, more sellable, more clients will
be liking using that software.

And if the software is really very much
user friendly, if it is very much

documented, the help files are very much
documented, then the user may not be

requiring a training to operate with the
software.

So, that is why the software should Should
be ease of use, easy to use and to learn

and also to know about the software
operations.

Efficiency.

It is the ability
to produce high performance software with

optimum use of
available hardware and software resources.

So, if we can execute a process,
if you can execute a thread, if you can

execute one software with optimum software
resources and hardware resources,

then obviously you can say that this very
software is very much efficient.

Extensibility.

When minimum effect to accommodate changes
in the requirements, design decisions and

due to change in the technical
constraints.

So, change requests will be coming from
the client.

Different types of hardware and software
changes will be there.

So, that is why if our software is capable
to accommodate those changes in the

requirements, in the design and due to
some change in the technical constraints,

if it can be accommodated accordingly,
easily, then obviously we can say that

extensibility of the software is up to the
mark.

On time.

A software should be developed well in
time.

So, it should be maintaining, the development
should be done within the deadline.

Portability.

It is used with which
software is transformed

to other hardware
or to other software platform.

So, what is the platform?

Platform is nothing but the respective
operating system and the hardware parts,

the architecture of the machine.

So, that is why if it is if it is
portable.

So, whether the portability is good enough
or not.

That means whether
it can move from, it can be

transformed
from one platform to another platform.

Readability.

It is the ability to produce a bug free
software.

Next one is the reusability.

It is the ability
so that the whole software or a part

of the software can
be reused in another software.

So, that is known as the reusability
property.

Next one is the robustness.

It ensures that
This ensures whether the software can

continue its
process in spite of unexpected problems.

So, that is a robust.

That means, the software is having some
constraints or having some problems,

but then also the software is executing in
a continuous process.

If it is so, then you can say that the
software is having a good robust feature.

Next one is the usability.

Software should have
an appropriate user

interaction
and meet the need of intended users.

So, user interaction, that is the UI,
user interface should be good enough,

so that users can, users will prefer to
use this respective software.

Within budget, the
software development costs should not

overrun and it
should be within the budgetary limits.

And if the software is within the budget,
then obviously, the software will get

better market, will get a greater market,
more customers, more users.

So, as a result of that, the software
development will get the full success.

So, these are the different features of
software quality.
