Verification and Validation

It is really important to do distinction between Verification and Validation.

Verification is mostly verifying that your implementation is following the requirements that the software team made by doing domain acquisition and talking to the domain experts.

Validation in the other hand, is when you go to the Domain Expert and show them the product and they approve that is right or wrong.

Obviously that is a really general description, but it is essentially that. The funny story is, that most people would think that something as simple as that is not useful in real life. But for me, and many other, in some interviews with some companies, they ask about that and it is really useful.
