Varification is a process that will confirm software will 
meet with product specification

Validation is process that will confirm software will meet 
the user Requirement & customer Requirement

Verification- is done at application developing stage. It 
is process oriented. It is prevention of the bug.
ex: verifying the docs like srs, proj plan etc.

Validation- is done at testing phase. It is product 
oriented. It is detection of the bug.
Ex: Testing the actual proj.

hi keshab
thank you responding
that means verification would be done before validation or 
not

verification - verify against business documents
Validation - Validate against software products

Hi,
Verification - Means wheather software meets its specific
requirements.

Validation - Means wheather software meets with the customer
requiremnts.

Varification - Are we building the product right.
Validation - Are we building the right product.

Plz correct me if i m wrong..

Many of them are telling like

Varification - Are we building the product right.
Validation - Are we building the right product.

i know that difference is there .but i could not get
can anybody tell that one.

The above answers I and II are opposit to the actual answer.
When you as a tester will be writing test cases based on 
SRS, you will be validating the things should be like this 
like that so that the client's requirements are met. 
Actually Developers would be paralelly working with 
seperately based on SRS.
Again when you get the build for testing, you will be 
running or executing the test cases to see that the 
application works as per validations or as per SRS. If it 
deviates, you will mark test case as fail and changing it 
to pass in regression testing if it is found ok then.
The first process is called validation. The second process 
is called verification.

varification deals with all paper works such as all types 
of specifications code on paper etc where as validation 
deals with actual product & envirment

1)Verification is done by the QA people
Validation is done by the QC(Testing) people.
2)Verification means the product is developing in right 
manner or not 
  Validation means the developed product is right or not.

Verification is process based  and validation is product 
based.

Hi Venktesh
as u asked 
Many of them are telling like

Varification - Are we building the product right.
Validation - Are we building the right product.....
The difference here is in Verification "product right" is 
mentioned means it is a ongoing Process of Developing 
Something which may be a System,Application or Product.Here 
we have to Follow  the steps with Verification how the 
Developing Process is going on.
But in the Validation "right product" is used Means after 
the Developement we have to Validate that Product as Right 
or Wrong...
Hopes You got a clear idea regarding this Post.

How to explain difference between verification and 
Validation? give the example ?
    Answer : Have you ever prepared an "Egg Omelette"! I am 
assuming that you have prepared. So how will you prepare 
an "Egg Omelette"? You will try to get all the ingredients 
required for making an "Egg Omelette" like - eggs, oil, 
salt, onion, and the other ingredients if any! Then what 
will you do? You will "verify" the ingredients and see if 
they are of good enough "quality" and in proper "quantity". 
Won't you? Here you are doing Verification.

Now let me assume that you have prepared "Egg Omelette". 
Now will you directly serve it to your guests? Or you would 
like to "taste" it to see if it has been prepared well? A 
good cook will choose to taste the dish before serving it 
to guests. This is comparable to Validation.

hi rose

till now i did not prepare "Egg Omelette" ,but what meat say
i got it..you explained in clear way..
Thank you very much
