v stands for verification and validation.
this model is combination of s/w quality assurance(sqa) & 
s/w quality control(sqc) with SDLC.
1.reviews in analysis:
  s/w development process starts with req. gathering and 
analysis.here B.A category people gathering req. from real 
client.analyst category people prepar brs and srs documents.
2.design: design category people prepare hld's & lld's
3.unit testing:here they r going to check whether progrm 
running or not with hnging,correctly running or not, fastly 
running or not,correctly program running or not.
4.integration testing:
 integration is nothing but interconnection in between two 
progrms.
4-approaches
   1. top-down
   2. bottom up
   3. hybride
   4. big-bang
5.functional and system testing:
  1.u.i.testing
     on preparing s/w we are conducting testing
  2.functional & non functional 
  3.manual support testing testing
    after complete s/w we r doing testing
6.user acceptence testing
  1.alpha  
  2.beta

V model stands for verification and validation
Verification is conducted on the document to ensure that we 
r following the correct process or not under verification 
we will be having reveiws,walkthroughs and inspections and 
also we will be having BRS,HLD,LLD,CODING.Determination of 
the correctness of the final program or software produced 
from a development project with respect to the user needs 
and requirements.In this we will be having unit 
integration,system integartion,UAT and others...

Plz let me know if this not correct

V model is one type of software development model.
left side of v model is called as designing and 
verification phase.
rightside of the model is called as validation phase
(testing phase).v model defines the realtionship between 
each phase of deignn phase and testing phase.

v model is basically a process in the software development 
and testing cycle.where v stands for validation and 
verification.from reqqquirement analysis to release of the 
build the complete process is catogrised and classifed into 
different stages in this model.where quality assurance is 
part of validation and quality ccontrol is part of 
verification.
plz notify me if any mistake

In this model u have checked the verfication and 
validation. In the left side phase we can called as 
verfication and the right side phase we can called as 
validation.  The left side phase consists of

1. BRS(Buisiness Requirement specification).
2. SRC(System Requirement Specification).
3. HLD(High Level Designing).
4. LLD(Low Level Designing).

once if all the stages are completed then a build is formed 
nothing but before going to construct a building a building 
plan is compulsory like that before going to test we must 
build.

in the build process also called verification in this 
process SQA (senior quality assurance) will involves to 
make sure that the each and every process is going correct 
or not.

in the center we have source code this must be developed by 
developers(programmers).

on the right side we have the following things.

1. UAT (User Acceptancy Testing)
2. FT (Functionality Teting)
3. IT (Integration Testing)
4. MT (Module Testing).

during the build process testing team going to prepare test 
cases 

UATCD (User Acceptancy Test Case Design)
STCD (System Test Case Design)
ITCD (Integration Test Case Design)
MTCD (Module Test Case Design).

once these test cases are prepared then the testing 
involving the testing like once the plan is ready we are 
going to construct the building like that once the test 
case design is over then it will be sent to testing team to 
test occordingly if they found any "bugs" (nothing but 
errors) immediately report to developers (programmers) test 
engineer only fix the bugs but developers rectify that bugs 
again this will sent to the testing team and the process is 
going on to all the modules.

This model is only follows MNC's because this model needs a 
lot of man power 

advantage of this model is 

1. High Quality (due to Verification and Validation).
2. Within time delivery.
3. Reduce the cost of project.
