scrum management

I found this string of interesting articles from steve denning, as far as i understand it SCRUM is a fast moving managment strategy found in sofware dev. companies, where they have to compete with outsourcing, this method has apparently huge productivity advatagies upto 400% is quoted. it is based on the whole team moving forward as one passing the ball back and forth, in short dev. cycles . the following approaches are observed, nothing new but as a whole....  

1. Organize work in short cycles:
2. The management doesn’t interrupt the team during a work cycle.
3. The team reports to the client, not the manager:
4. The team estimates how much time work will take:
5. The team decides how much work it can do in an iteration:
6. The team decides how to do the work in the iteration:
7. The  team measures its own performance:
8. Define work goals before each cycle starts:
9. Define work goals through user stories:
10. Systematically remove impediments:
