Looking at the definition of those two words, you could just as easily 
reverse the wording of the last two paragraphs and you would be equally 
correct.

The company I work for has a group called DVT (design verification and 
test).  They are the high level testers... the final stage prior to 
product release.  I'll bet others in the group have similar "final test" 
groups that use the word validation rather than verification.

In my opinion, the words have close enough meanings that confusion would 
result if an organization tried to use them, by themselves, to mean two 
different things.

Have fun,
