I just don't bother to shorten it...

- Did we correctly understand and build what the customer asked for

- Did the customer actually ask for what would solve the problem they are trying to solve

The second one is very important to ask early on, and _not_ asking it can cause a lot of wasted time. When I'm in a position to comment on whether I think someone fits the requirements of a senior developer, whether or not they ask that question plays directly into it.
