Varification:  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.

RE: What is difference between Validation and Verification
Verificartion: Typically involves rreviews and meetings to evaluate documents, plans, code, requirements, and specifications. This can be done with checklist, issues lists, walkthroughs, and inspection meetings.
1. This process focus upon the process of an organisation
2.verification begins in the initial phase and will be always associated with all the phases of SDLC
3.Mostly QA(Quality Assurance ) engineers will be involved in the process of verification.
4.are we building the right system?

Validation: Typically involves actual testing and takes place after verifcations are completed
1.This process focus on the product after the development(The out come of the work)
2.Validation appears after coding phase
3.Most of the times test engineers will be involved in the phase of validation.
4.are we building system right?

verfication - like cross checking eg: modules are prepared as per specification
validation- comparing with specification whether we prepared modules as per specification

RE: What is difference between Validation and Verification
VERIFICATION :

If we are only verfiying our system/ application on papers like Reviews , meetings etc where no execution of the test cases involved.


VALIDATION :

While Execution of the test cases when we are validating our system/ application is validation.
