SDLC is Software Development Life Cycle. It is used to
develop the software systematically .
SDLC have main 7 Stage:
1. Priliminary Investigation
2. Feasibility Study
3. Analysis
4. Design
5. Coding
6. Testing
7. Maintainance & Review.
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.
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.
Sdlc is the standard procedure followed to build a software
types of Sdlc :
1.Waterfall model
2.Spiral model
3.V or V and V model
4.prototype model
5.Hybrid model
Different stages in SDLC :
*Requirement collection
*feasebility study
*making CRS into SRS(system requirement pefication)
*Design
*HLD
*LLD
*coding
*testing
*implementation
*maintainance
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
Softwate Development Life Cycle..
this is a process used for developing any software. for this
following five steps are considered..
1. requirement analysis
2. designing
3. coding
4. testing(unit and integration testing)
5. implementation of s/w and maintainance
SDLC is Software Development Life Cycle. It is used to

SDLC have main 7 Stage:

2. Feasibility Study
3. Analysis

6. Testing
7. Maintainance & Review.
sdlc means system development life cycle this is the
procedure to create the new system. the different stages
used in the sdlc are:
1. initial investigation or recogination of the need
2.feasibility study: feasibility study has to be satisfied
the following feasibilities:-
a.behavioral feasibility
b.economics feasibility
c.technical feasibility
d. legal feasibility
e.social feasibility
3. system analysis.
4. system design
5.system tesing;-testing are of many types such as
a.unit testing
b.behaviour testing
c.software testing
6.implenentation
7. post implementation
8. maintanence

1> Requirement Analysis
2> High level design
3> Dedicated Specifications
4> Coding

Assignment
A software house got a project to automate sales/purchase
department of a furniture store. The store management is
clearly transferred their requirements to the software
house management. There is no chance of changing the
requirements afterwards.
Software house management use waterfall process model to
make the project.
Given is the progress flow of water-fall process model
In waterfall process model, the deliverable (document)
produced in one phase serves as an input to the next
phase.
Suppose you are a project manager who is leading this
project. It is decided to work and complete the project
using waterfall process model approach. You are required to
develop a plan in which the key task is to decide the
deliverable that should be built during and after
completion of each phase. Also give a description or
required contents that must be included in those
deliverables.
You are not supposed to make the complete project. All you
are required to do is to make a Project plan. In that, you
need to give a set of deliverables (documents) which
according to you, should be developed in each of the phase
(Requirements, Designing, implementation, Testing,
Maintenance). Also provide contents which should be there
in each deliverable. The contents should be clear and have
brief explanation.
Note:: There are one folder and one file in the attached
folder. The file is named as Assignment 4 write-up which is
your assignment write-up. The other folder named Project
deliverables is the folder in which you are required to
organize and place your deliverables. Name of the
document/deliverable saved in each folder should be
mentioned in the file named checklist (This file is placed
in the “Project deliverables” folder)
For Example
If you produce a deliverable named Requirement
Specification (RS) in the “Requirements” phase. You need to
do following tasks
1) Finalize the RS contents
2) Save the file in sub-folder named Requirements
3) Write the name of this document in the checklist
file under the heading Requirements.
Similarly, you need to make and save deliverables of each
phase. Not all phases contain one deliverable. There must
be some phases having more than one deliverables.
PLEASE SIR PRIVIDE ME THE CHECK LIST FOR GIVE SENERION ?
CHECKLIST ARE:
1-Requirements
2- Designing
3- Implementation
4- Testing
5- Maintenance
