V model stands for Verification and Validation.
V model defines the mapping between development stages and
testing stages.

Verification:
It is used to check whether the people are developing right
system or not.
Validation:
It is used to check whether the developed system is right or
not.

Hi

QA process comes under VERIFICATON
QC process comes under VALIDATION

VERIFICATION -- Are we building the right product
VALIDATION --- Are we building the product right

Answer / deepti

The four main process phases – requirements, specification,
design and
implementation – have a corresponding verification and
validation testing phase.
QA is Quality assurance and covers all process related to
software verification like reviews(Peer review, code
review) , audits ,meeting etc.
Verification is for Defect Prevention.
QC is Quality control and covers all process related to
software validation. Includes actual testing. Running test
cases and producing test results.
Validation is for Defect Detection.

Answer / mahesh badale

hi all , Basically QA and QC has to go hand in hand else
better quality can not be achieved.
In 'V' model left arm of V deals with the quality assurance
process and as creating plans , strategies, writing test
cases , reviewing all and other process where as right arm
deals with actual execution of testing and reporting.

Answer / peter

About verification and validation: answer #3 is correct.

According CMMI:
Verification: Confirmation that work products properly reflect the requirements specified for them. In other words: verification ensures that "you built it right".
Validation: Confirmation that the product will fulfill its intended use. In other words, validation ensures that "you built the right thing".

About QA and QC:
QA is about quality of processes and QC is about quality of products. Therefore, verification and validation are both part of QC.

Again according CMMI:
Quality assurance: A planed and systematic means for assuring management that the defined standards, practices, procedures and methods of the process are applied.
Quality control: The operational techniques and activities that are used to fulfill requirements for quality.
