Characteristics of a good software.

So, how can you judge that our software
whatever we have developed is good or not?

A software product can be judged by what
it offers and how well it can be used.

So, usefulness
of the software can be a good measurement

to decide whether the
software is working good or not.

So, this software must satisfy on the
following ground.

So, we are considering three grounds
on which you

can decide
whether the software is good or not.

The first one is the operational,
next one is about transitional and the

last one is our maintenance.

Well engineered and
crafted software is

expected
to have the following characteristics.

So, first one we are considering this one
as This tells us how well the software

works in operations, it can be measured
on.

So, we are trying to get that how the
software is good in the operation.

So, what are the, what are the metrics we
are having in our hand?

One is the budget, usability, efficiency,
correctness, functionality, dependability,

security and safety.

So, these are the points which will be
coming under the operational.

So, depending upon them, we can decide
whether the software is good or not.

The software must be within the budget.

A software should have a good usability.

Software should be efficient.

It should be also very much secured.

The safety of data is ensured.

It is giving us the correct answers,
correct results are getting obtained.

It is efficient.

That means, it will
give us the required result

within the
minimum, optimum amount of time.

The functionality,
the dependability, all

these are the features
under this operational.

So, now next, we are going for this
transitional.

This aspect is important
when the software is

moved from one platform
to another platform.

So, platform means operating system and
the respective architecture of the system.

Combining them, we usually call it as a
platform.

So, whenever a particular software will be
moved from one platform to another

platform, then in that case, the
portability, the interoperability,

The proper
ability, the reusability and adaptability

are the main features
under this transitional.

Next aspect we are going to discuss is our
maintenance.

So, this aspect briefs about how well the
software has the capabilities to maintain

itself in the ever changing environment.

So, that is our maintenance.

We know that whenever a software will be
in operation, so multiple change requests

will be coming, multiple changes are to be
carried out on the software.

And that is falling in the part of the
maintenance of the software.

So, how this maintenance can be fruitfully
executed on the pre-existing version of

the software that will be also a good
measure whether the software is good or bad.

So, here under this one we are having four
points that is the modularity,

maintainability, flexibility and
scalability.

So, these are the four points What is
coming under this maintenance?

So, in short, software engineering is a
branch of computer science which uses

well-defined engineering concepts required
to produce efficient, durable,

scalable in budget and on-time software
products.

So, you should have the software with this
respective features that means,

it should be efficient, it should be
durable, it should be within the budget,

it should be on-time, it should be
scalable.

So, these are the features which you are
expecting from a good software.
