Scrum - my first encounter

I am just reading a great article which talks about how to use Scrum in a real project situation. It's an really interesting and fun article.

However I am not yet convinced - it seems to be a lot of "that is not so important", "approximately" and "document if you think that you need it". I still miss the use case, the technical specifications and the system architecture. Maybe if i read to the end i will be converted.

With that said; the methodology contains some very interesting concepts and ideas, and i will most certainly incorporate elements already now.
