Excel Product Backlog and Sprint Management
This one takes me way back. This is what I first used when I started out as a ScrumMaster. There were no awesome tools like VersionOne, we had to use Excel. This is an Excel template for managing your backlog, sprint backlog, and for showing burn downs and release plans. It has got it all. I don't remember where I got it from, but check it out. One thing about it, it was fast and easy to update once you figured out the template. Read the comments for more info on how to use it.
