    Hello Readers...

    By this blog i am trying to explain the difference between the ‘Verification’ and ‘Validation’. I hope this way of presenting is very easy to understand for all the test engineers. 

     

    S.No. Verification Validation
    1- Verification is the procedure of verifying that the software or application matches its requirements. Validation is the procedure of verifying whether the specification fulfill the client's requirement.
    2- Verification is a kind of the static testing. Validation is a kind of the dynamic testing.
    3- It is assigns requirements of the consumer. It  assigns to the accuracy of the execution of the requirement by application.
    4- Verification inspect for the different parts like- coding section, documents section , planning section, requirements, specification etc. Validation inspects the entire application or product.
    5- Verification is a type of internal procedure. Validation is a type of external procedure.
    6- There are few inputs for the verification like review, walkthrough, investigation, meeting and checklist. Inputs for the validation are real testing of the real product or application. 
    7- In the verification we worked on the concept like- Are we constructing application or product right or correct ? In the validation we worked on the concept like- Are we constructing right or correct product or application.
    8- Verification is the first action for any product or application. Validation is always performed after the verification activity.
    9- Verification is a kind of QA method. Validation is a kind of QC method.
    10- Verification is normally procedure oriented. Validation is normally product or application oriented.
