Alicia Yanik has a great article on her experiences implementing Scrum over on stickyminds.

We had the Scrum logistics in place, but I struggled with harnessing the team’s power…

Then I took a closer look and noticed the team problem solving, self-organizing, and trying out Scrum practices without any nudging from me. Within a month of their introduction to Scrum, the team was making changes to their environment and beginning to introduce new practices into their coding conventions. Within six months the team decided to re-architect their entire code base – to make it more Agile!

Yep.

This is the story I hear from teams that implement various flavors of Agile methods. The team takes on a management role, managing their work, processes, and inclusion/exclusion.
