Agreed. His argument is essentially that you can't meet deadlines with Scrum, because you must always be in a 'shippable' state at the end of each sprint.

I'd argue that if you can't meet deadlines with scrum, there's no way you'd meet them without it. His definition of 'shippable' is very narrow--like you said, just because it doesn't meet console certifications doesn't mean that it's not "doing scrum".

I wouldn't put the app I've got after the first dev sprint on the app store, either. It's not done.
