Just my point of view:

I disagree with Ralf.

Scrum is here NOT to solving ANY of YOURS problems. It's like a car - it's give you ability to drive, but how you drive is up to you. If you can't drive - you drive nowhere. If the street is broken - you can't drive, too.

What Scrum do, based on it's pillars (Scrum Theory, http://www.scrumguides.org/scrum-guide.html), is ability (and force you) to solve your own problems. Not more. OK, there are some preventive things and some sort of problems just don't happen with Scrum (if you can drive, of course), but it's not goal of Scrum.

And because, I think, there is no alibis at all. It's just disability to drive.
