Software Measures and Matrix.

So, this particular software measure and
matrix is nothing but one process for the

quantifying and symbolizing different
attributes.

So, let us go into the details of this
topic.

So, software measures can be understood as
a process of quantifying and symbolizing

various attributes and aspects of a
software.

So, we want to measure the different
features of the software.

So, that is why the quantifying this word
has been evolved in this definition.

So, software
metrics provide measures for various

aspects of software process and the
software product.

So, software measures are fundamental
requirements of software engineering.

Ultimately, software is an engineering
product.

So, they not only help to control the
software development process, but also aid

to keep the quality of ultimate product
excellent.

So, if you can go on doing some
measurements, having some matrix in

different aspects of the software.

So, that will also ensure that how for
good

quality of software
we are going to develop.

So, according to Tom DeMarco is one of the
very famous software engineer,

he has made one statement that you cannot
control what you cannot measure.

So, that is very interesting.

You cannot control what you cannot
measure.

So, by saying it is very clear that how
important the software measures are.

So, now let us go for some software
metrics, how to do this software,

how to, what are the different aspects of
software metrics.

So, size metrics.

So, first one we are considering.

The lines of code that is the LOC and
mostly calculated in thousands of

delivered source code lines, in short it
will be denoted as KLOC.

So, depending upon the value of this KLOC,
the software metrics can be done,

the measurements
can be done and this size

metrics is one
of the metrics of that measurement.

Function point count.

It is a measure of the functionality
provided by the software.

Function point count defines the size of
functional aspect of the software.

We know that each and every function point
is actually implementing one of the

functional requirements of the software.

Complexity matrix.

So, Maccab's cyclometric complexity
quantifies the upper bound of the number

of independent
paths in a program which is perceived

as complexity of the
program or its modules.

So, how many number of independent paths
are flowing through a software?

So, that will be also another
metric and this metric is known

as complexity matrix and
that is a psychometric complexity.

So, it is represented in terms of graph
theory concepts by using control flow graph.

So, we are having a separate video on this
respective aspect.

So, quality matrix.

So, defects, their types and causes,
consequence, intensity of severity and

their implications define the quality of
the software.

So, in our software we are doing different
kinds of risk management.

So, each and every risk should be done
some intensity values.

So, that is why
we are having the intensity of severity

and that implication defines the quality
of the software.

Next one is the defect count.

The number of defects found in the
development process and number of defects

reported by the client after the product
is installed or delivered at the client

end define the quality of the product.

So, defect count
is a very important and very obvious

measures
and metrics for this software quality.

So, how many defects has been detected
after getting it installed at the customer

side and how many against how many defects
the customer has put the feedback.

So, that might be also a good metric to
decide the quality of the product.

Process metrics.

So, in various phases of SDLC,
the methods and tools used, the company

standards and the performance of development
are the software process metrics.

So, what are the different in case of
different SDLC, the methods and the tools

whatever you have used.

So, that might be also another metrics
known as the process metrics.

Next one is our resource metrics.

There is a effort, time and different
resources deployed on that very particular

software will be a good measure for our
resource metrics.

So, now, in our earlier
video also, we have

discussed a lot
on this resource management and all.

You can also have a look on those videos
for the better understanding.

So, that is
why in this particular video, we have

discussed the software
metrics and the respective measures.
