Mark Levison has written up a great list of Scrum Smells on his blog Notes from a Tool User. Check them out! There is a lot of great information there. He also asks your help: if you know of common problems with Scrum, see if you can add them to the list!
There’s a great discussion on the Extreme Programming Yahoo! group where a whole bunch of folks list their blogs out. If you aren’t part of the group, you should probably join it (it focuses on technical practices, and there’s lots of other good agile stuff there too). The discussion starts with a message from James Carr where he asks who else here blogs?
It’s probably still cool to jump in with your own blog link if you have an agile-focused blog (I’m sure Scrum, Lean and other agile methods would be welcome even though it’s an extreme programming list!)
I just read through this article about Requirements Management in an Agile World. It’s a pretty brief article (just the one page), so there isn’t too much there. Have a read, and then come back here and tell us all: what is wrong with this article?
J. B. Rainsberger has written an excellent article about the usefulness of planning velocity (and the places where it is not useful as well). I highly recommend reading it, particularly if you are a manager or a project manager.
