proper punctuation

[Iryn_]

Hello! Here is a part of an article:

Were the executed tests really designed to catch the most defects? or where they designed to see if the software matched the user's requirements?

I believe the punctuation is not that good here.
I would either start the next sentence with a capital letter after the question mark ( Or were they designed...) or unite two parts into one sentence (...to catch the most defects or were they designed...?)

Are my suggestions correct?

Yes, they are.
