hello everybody and welcome today we
will be talking about uh SRS what is SRS
how to create SRS and why we use
SRS please watch this video till end so
that you can have a better understanding
of
SRS clear requirements help development
teams create the right product and a
software requirement specification helps
you lay the ground work for product
development we will Define what this is
when you would use one and five steps to
write an SRS
document what is a software requirement
specification
document a software requirement
specification is a document that
describes what the software will do and
how it will be expected to perform it
also describes the functionality the
product needs to fulfill all
stakeholders needs for example business
or users a typical SRS in includes a
purpose and overall description specific
requirements the best SRS document
defines how the software will interact
when embedded in Hardware or when
connected to other
softwares good SRS document also account
for real life
user so now let's review the reasons for
using
SRS SRS describes how a software system
should be
developed it provides everyone involved
with a road map for that
project SRS in software engineering
creates the basis for all documentations
it sets your communication on the right
track it helps you understand the
product SRS documentation helps to grow
your development standards it helps to
cover risk on each development stage so
there are five steps to create SRS a
good
SRS the number one is start with outline
then clarify project overview then
understand users and project risks
detail the project requirements and get
the SRS approval at the final
stage so let's discuss about the SRS
outlines as always it is important to
make your document structured and
focused this will help your Outsourcing
development team avoid unnecessary
effort in Reading project requirements
back and forth as a result it will
reduce the risk of missing information
across the teams you should also ensure
the three main parts of the SRS
including introduction overall
description and detailed features at
requirements to create a good
Outsourcing software
document now let's take a look at an
outline example
here the first thing is Introduction
within introduction you can write
project purpose project scope glossery
and reference the second is overall
description where we can write user
needs assumptions and dependencies and
the third is detailed features and
requirements where we can write actually
the functional requirements
non-functional requirements external
interface requirements we'll go into
detail of all these one by one so let's
start with
introduction in introduction we clarify
the project overview starting the SRS
with a clear introduction to describe
the project purpose and give readers an
overview of the project big picture the
introduction should cover the following
content the number one is Project
purpose what is the project built for
answer this question to help the readers
understand the aims and objectives of
the
project the second is Project scope what
is the business goal what values does
the project deliver find the answer to
these questions to make clear the
project sophistic ation glossery and
reference explain the terms used in the
document show your references to readers
to consolidate the transmitted
information so the next is overall
description here we understand users and
project risks all developing effort is
to ensure that the project is completed
and meet the user
expectation to achieve this success you
need to pay enough attention to
analyze user
needs Define your software's end user
and how they use
it correctly understanding the users's
needs will give you a clear Direction on
how your software should be
built assumptions and dependencies think
of assumptions and dependencies that
might impact fulfilling the requirements
outlined in your
SRS and take not note of external
factors for example software components
reused from another project this is to
prepare for any upcoming challenges in
the project implementation and reduce
the risk of project
failure so now about features and
requirements where we can actually write
the project requirements in detail clear
requirements can be considered as keys
to the project deliverables in general
and the project success in particular
the more specific requirements the
easier it will be for the developers to
plan and implement the
project requirements are various but
mainly divided into functional
requirements non-functional requirements
and external interface
requirements each type of requirement
needs to be specified direct and
differently so let's talk about
functional
requirements functional requirements
describe what the software will do and
Define how it will function to meet user
expectations you should also mention the
acceptance criteria for these functional
requirements to determine if a function
is completed and performs as
expected non-functional requirements
non-functional requirements include
usability performance software Quality
Security and so
on they can be seen as extensions help
describe how the software will
perform external interface
requirements external interface
requirements are types of functional
requirements and these interfaces
include user software Hardware system
communication interfaces
Etc so the last thing is get the SRS
approval to ensure the SRS accuracy and
objectivity and the mutual agreements in
how the software should run
the key stakeholders should be involved
to approve the SRS by doing this you can
reduce the risk of wasting time effort
and money in the future unnecessary
changes so as a final thought the SRS is
important because it gives you a source
of information where you can easily
manage requirements throughout the
Outsourcing software development process
in this video I aimed to help you get
the basic ideas of the SRS structure and
Hope hopefully I did
it thank you for
watching
