Examination Techniques5: Validation and Verification
The constant and never ending challenge to ensure examination tools meets the requirements when used with or applied to the DUT (device under test) naturally generates constantly evolving polices, practices and procedures. The 'digitally-evolving' and 'technology-fast development' age has brought with it an inability to keep policies, practices and procedures up-to-date. That includes the tools and techniques that maybe used or applied.

When considering Validation and Verification they hold the same unlying warning as that attributed to Galileo, who said "the Bible shows the way to go to heaven, not the way the heavens go". Thus agreeing that validation is being performed does not necessarily mean verification will automatically support that claim.
