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.

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

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.

Verification and validation is a form of testing that defense against error
prone software development and maintenance process.
Verification and validation are not the same, verification shows conformance
with the specifications and validation shows that the program meets the
customer's need


Verification : is a type of static testing as software inspection is convened
with analysis of the static system representation to discover problems.
Formal approach to document reviews
Intended explicitly for defect detection but not correction
Cannot check non functional characteristics such as performance, usability etc.
Many defects can be discovered in single inspection
Verification can be done on Requirements, specifications, design docs, Code


Validation : is a type of dynamic testing as software testing concerned with
exercising and observing product behaviour
One defect may mask another defect so several executions are required
Intended explicitly for correction
Validation is done in actual application and may be done on Prototype Validation
Take place after verification


Verification: Verification is a process to ensure that the software that is made, matches the original design.  It checks whether the software is made according to the criteria and specification described in the requirement document. it is to check whether you built the product right as per design.

Validation: Validation is a process to check whether the product design fits the client's need. it checks whether you built the right thing. it checks whether it is designed properly or not.

verification:-is checking versions of data have been entered identically or has been copied correctly from one medium to another. it is done manually after completing the data entry

validation:- it is checking the entered data whether it is acceptable . usually it is performed while entering the data by the computer program

Verification: Verification is finding defects or faults by reading out the documents. Example-review of any document

Validation: Validation is finding defects by executing test cases or testing the product.

Verification is basically done when it is a written document/code/etc i.e. that is checking whether we have done it in the right way/ are we building product right.

Validation is done basically when the system is in execution i.e. that is checking whether we have build the right product/ whether meeting all requirements.

Please note that, it is not necessary that a systems 100% correctly verified will have 100% correctly validated.

It is done each phase from starting itself

VALIDATION: It is product oriented.
whether the right product is built.
It is done after the execution phase
