Software Developmet life cycle comprises of the following
different stages.

1) Information Gathering
2) Requirement Analysis
3) Design
4) Coding
5) Testing
6) Implementation & Maintenance.

Information Gathering : In this phase; information is
gathered from the customer , if some information are
missing then we need to go to customer and take the
required information. Mainly this is done by the Business
Analyst as they are the one who are completely involved in
Software Development life Cycle.
The Document Prepared during this phase is : Business
Requirement Specification (BRS)or Customer Required
Specification( CRS) Or User Requirement Specification(URS).

Entry Criteria : BRS OR CRS or URS.

2) Analysis Phase : The Features and the functions that
need to be put in the project are determined.

Entry Criteria : Business Requirement Document
Exit Criteria : SRS ( Software Requirement Specification)

3) Design Phase : The actually flow of the project is done
here.Deciding upto logical functionality ,ER diagram , Data
Flow etc are made. These activities would be executed by
team lead , technical Specialist and depending upon the
work appropriate decisions are made.
Document prepared during this phase are HLD, LLD
HLD : Defines the overall Hierarchy of the function.
Example : Login into Net Banking. From the root level to
the least level is defines in HLD.

LLD: Internal logic of the project is defined. Focuses on
thei nternal functionality of the program. Each and every
module logic is defined.

Entry Criteria : SRS
Exit Criteria : Design Document.

4) Coding Phase : Based on the design document , small-
small modules are prepared . All the modules are summed
together to form a .exe

Entry Criteria : Design document
Exit Criteria : .exe
Unit testing , integration testing & white box testing
comes in this phase.

Testing : Actuall system testing take place here.

Implementing & Maintenace : I think all know this.

SDLC defines as SOFTWARE DEVELOPMENT LIFE CYCLE
It is defined as how well our application is build
in meeting the customer requirement and customer
expectation.

The different stages are
1.Information Gathering: In this phase Bussiness Analyst
will gather all the information from customer requirement
and prepare B.R.S. documents.
2.Analysis: In this phase Senior Business Analyst will
prepare S.R.S documents.
3.Design: This is done by the Cheif Architect.
4.Coding: This phase is done by the developer.
5.Testing: This phase is done by Test Engineeers.
6.Release and Maintance: all sr.department will release the
product .
In maintance the maintance team will change the software
if necessory.

Acronym for system development life cycle. SDLC is the
process of developing information systems through
investigation, analysis, design, implementation and
maintenance. SDLC is also known as information systems
development or application development. SDLC is a systems
approach to problem solving and is made up of several
phases, each comprised of multiple steps:
• The software concept - identifies and defines a
need for the new system
• A requirements analysis - analyzes the information
needs of the end users
• The architectural design - creates a blueprint for
the design with the necessary specifications for the
hardware, software, people and data resources
• Coding and debugging - creates and programs the
final system
• System testing - evaluates the system's actual
functionality in relation to expected or intended
functionality.

1. Planning – before a program is created, they have to know
what they want to create. Software development companies use
this stage to determine the need of the present market.
Surveys and project proposal are common in this stage. They
sit down and determine what the present market needs.
Management is often involved in this stage as they wanted to
determine what the developers have to do and how it will
impact the market.

2. Design – once the management has approved of the plan and
the budget has been determined for this project, it’s now
time to create the architecture of the program. Developers
will work together and talk about the ways of developing the
program. The workflow of the software is drafted in this
stage. Some software development models approach this stage
in a rather simple manner. The iterative development model
often treats this stage as already the beginning of
software’s actual creation. The initial programs are
creating in this part of development model.

3. Testing – developers have to make sure their created
programs will work well in different environments. The
traditional way of testing usually needs testers so that the
program will be exploited in different manner. On the other
hand, some software developers do not use testers for their
program rather developers get normal and intended users to
test their program. They do not just implement the program
to everyone though, they implement the program in restricted
manner so that they can monitor to software’s performance
and make the necessary adjustments even before the software
is released for general public. The testing stage even
expands to the idea of implementing the software in beta
testing just to make sure it can withstand multiple users at
the same time.

4. Implementation – once testing is finished and the
software is proven good for implementation, it is released
to the public or will be removed from beta version. It’s
expected that on first days, developers will face serious
challenge of fixing different bugs as they are discovered
one by one by different users. The main difference of the
implementation stage to the testing is the amount of bugs
expected. Since they are implemented to the public or a
wider audience, it’s already expected that it should work
properly.

5. Maintenance – with the software properly implemented,
developers role in this software does not end there.
Instead, they will have to work reactively for this
software. Instead of looking for the problems in their
created software, developers will only be providing answers
to their problems.

rong>6. Termination – of course not all software will last
forever. Updates has to happen and there will be time that
drastic changes has to happen in a software that they have
to be scrapped altogether. Although there will be traces of
the previous software, the evolution of new coding language
or the adaptation of the same software to a different
platform will warrant termination to the original program.

SDLC has to follow steps faithfully. These steps suggest
what type of development software they are. Although they
follow almost the same stages, it’s the treatment of these
stages suggest what they can do. Developers on the other
hand should consider their own skills, their intended users
and the available resources to determine what model they
should be following for software development. This will
ensure they are creating something that they can control and
maintain at anytime of the day. With proper steps and
guidelines, a good software is ensured for the users.
