    The second difference given is wrong…..

    It should be –

    verification = Did we build the system right…(conformance to specifications)

    validation = did we build the right system(Conformance to customer requirements)

    Guys, it is impossible to distinguish them. When you test software, you test it against requirements (written or implied). If written requirements do not agree with intended use, this is requirements verification, not product validation. There is no point in two terms.
