Tomek’s tray notes on Scrum

As Nigel Baker was giving his speach titled “10 tips that ScrumMasters should know, (but probably don’t!)” at Winter Agile Tuning, Tomasz Przybysz was taking notes on a paper tray. I’ve heard the talk was pretty good and a few people were trying to copy his tray. Since the original presentation is not yet available, I thought I’ll help with putting my own photo (phone quality) on-line. Maybe Tomek will take a while to put some insight into his notes? What say you, Tomasz? Click on the image to get the full (readable) size version.

5. OpenID (login via gmail)
6. OAuth2 (login via Facebook)

We need authorization based on rules described in our domain.

The method for accepting chapters, looks like this:
