Transcripts
meet Adam an aspiring entrepreneur he is
interested in hosting an online store
for home decor products like bases
curtains artwork and Home Furnishings he
requires a software application that
would allow the customers to browse the
available products at their fingertips
and buy them online
Adam eager to jump into his new business
wanted to understand how the software
development process works to start with
his business idea Adam meets his cousin
Mark who is a software developer and a
good one at it he pitches his idea and
asks his cousin to help him design an
online business application
Mark explains to Adam the way of
Designing the best online shopping
application we need to understand the
working of the software development
lifecycle also known as the sdlc it
involves distinctive phases to initiate
the software production based on the
client requirements
further Mark briefs Adam about the six
crucial phases of sdlc in designing any
software application
planning requirements phase requirement
analysis phase designing phase
implementation phase testing phase
deployment and maintenance phase
the development team will commence
production post agreeing on the terms
and conditions discussed between the
client and the development team
regarding all the proceedings and
requirements
initiating the production with the
planning requirements phase where the
client and the development team will
discuss the basic requirements for the
software like the purpose of the
application the details about the end
user of the product key elements like
format and attributes of the application
for Designing and the overall user
interface's design of the software the
development moves on to the second stage
the requirement analysis phase which
includes the detailed information about
each element to design the software is
discussed validating the installation of
elements in the application according to
the client's requirements calibrating
the security protocols and Performing
risk analysis for the software
application and all the discussed
details are then to be filed in the
software requirements specification
document also known as the SRS document
after completing the second phase third
stage of software development the design
phase the software designers will devise
the system design following the SRS
document the system design defines the
overall architecture of the software and
checks its feasibility with the client's
requirements
all the details of the design phase are
added to the design document
specification also known as the DDS
document and shared with the analysts
and stakeholders for review
next the development moves on to the
fourth stage the coding or
implementation phase in the coding phase
the developers start writing the code
using the languages they choose for the
software development the coding stage is
also one of the most important phases as
it encapsulates the implementation of
the software product
the developers use predefined guidelines
and development tools like compilers and
debuggers to implement the code
the next phase of the production is
where we begin with the fifth stage of
software development the testing phase
the develop software is now deployed in
multiple test environments to check the
functioning of all the attributes in the
software architecture after the test
cases are completed the quality
assurance and the testing team may find
errors or bugs in the software which
will be forwarded to the developer team
for debugging this testing and debugging
process continues until the software is
stable and works per the required
specifications
as for the last stage in the sdlc life
cycle the deployment and maintenance
phase is initiated
with the testing phase completed the
software application is ready for
deployment and consumer use
in this phase the development team will
set up links for the application and
make it accessible to the users after
the deployment is completed and users
begin using the application they may
encounter an error or a bug in the
application which is to be solved from
time to time
maintenance also includes releasing
application updates and enhancements for
the software for better performance and
user experience
Adam at this point was surprised by all
the effort and steps taken by the
development team to design a software
application and the key phases involved
in sdlc
and on that note here's a question for
you all what does the design document
specification document include software
code details on defects and bugs
software architecture details software
requirements give it a thought and leave
your answers in the comments section
below three lucky winners will receive
Amazon gift vouchers
with Mark's explanation of the sdlc life
cycle Adam understood how software is
developed now he can actively give
feedback to the development team and
design the best software application for
his online store and maybe expand to
other businesses as well we hope you
