Verifiaction:Means are we doing right thing.i.e we have to 
check whether we are implementing right process.

validation:Means are we doing things right.i.e we have to 
check whether we have developed a software as per the 
client requirement.

Verification is done through out the life cycle of the 
project/product where as validation comes in the testing 
phase of the application.

Verification ensures that the application complies to 
standards and processes. This answers the question " Did we 
build the right system? "

Eg: Design reveiws, code walkthroughs and inspections.

Validation ensures whether the application is built as per 
the plan. This answers the question " Did we build the 
system in the right way? ".

Eg: Unit Testing, Integration Testing, System Testing and 
UAT.

Varificatio:it is the process of confirming that s/w "meets 
its specification".It involves reviews and meetings to 
evaluate documents,plans,code,requirement and 
specification.This can be done with checklist,issues lists 
amd walkthroughs.
It is the examination of the process and checks r we 
building the product right?
Validation:It is the process of confirming that it "meets 
the user's requirements".Validation typically involves 
actual testing and take place after varification are 
completed.

Verification takes place before validation,and not 
viceversa. Verification evaluates 
documents,plans,code,requirement and 
specification.Validation evaluates product itself.The 
inputs for verification are checklist,issues 
lists,walkthroughs and inspection meetings,reviews and 
meetings.The input for validation is actual testing of an 
actual product.The output for verification is nearly 
perfect set of documents,plans,specificationand requirement 
document. The output of validation is nearly perfect product

Verification : 'Are we buliding a Product right?'it is a 
static testing method.
Validation : 'Are we building a right Product?'it is a 
Dynamic testing method.

verfication : A stage wise verfication of Design at 
different stages thorugh test cases or reviews or any other 
tool

validation: chekcing whether product designed meeting 
client inputs and working as per the requirement It may be 
validated by client or by practical validation on simulation

verication is to check we are doing right..
validation is to prove we have done right..

Verification -> Are we building product right?
Validation -> Are we building right product?

- Verification evaluates documents, plans, code, 
requirements, and specifications. 
- Validation, on the other hand, evaluates the product itself. 

- The inputs of verification are checklists, issues lists,
walkthroughs and inspection meetings, reviews and meetings. 
- The input of validation, on the other hand, is the actual
testing of an actual product. 

- The output of verification is a nearly perfect set of
documents, plans, specifications, and requirements document.
- The output of validation, on the other hand is the
actual/perfect product.

=> Verification comes before Validation.

verification-

1 it emphasize on building the product right.
2 it is a low level activity.
3 it only checks the correspondence between a program and 
its specification.
4 we do the Defect Testing to uncover errors.
validation-

1 it emphasize on building the right product.
2 it is a high level activity.
3 it checks that whether the software is operationelly 
useful or not.
4 we do the Validation Testing to meet the customer 
requirements.

verification is simlpy a method by whch we check that is we 
are making the things right or not?means applying right 
procedure or not,committing any mistakes or not and so on.

Validation is a process by which we check that is we are 
making the right product or not,means the produt we are 
making is as per as the client requirement or not.

Verification - Suppose, as per requirement we r supposed to
design a view with define number of values. So, to check
whether the view has that particular values on the view or
not.. this process is known as Verification. Verification of
Requirements.

Validation - Now, we need to test the view whether that
values defines on the view are functioning properly or not.
This process is known as Validation. Validation of
functionality.

Please correct me if I am wrong.
