High Notes offers a blog post called "How to do SCRUM with Basecamp?"
About 2 years ago we were sitting at the office trying to figure out which tool to use for project management. I mean, being agile is about being simple, but index cards were starting to get messy...Of all the tools we tried, the one that gave us the best results was Basecamp. These are the two reasons that we believe make Basecamp great for agile project management:
Simplicity: There is no need for training when you start using Basecamp. In essence Basecamp is a set of message boards, blogging tools, calendars and to-do list trackers. All these tools combined in an intuitive way is what Basecamp is all about. If your team can't figure out how to use Basecamp... you're in troubles. Being agile is about using the simplest tools available.
Interactions instead of Process: The purpose of Basecamp is to promote and enhance collaboration between a team. Basecamp doesn't try to force you into a specific workflow as most project management tools do. You can pretty much do whatever process or workflow you want, and still, Basecamp is going to be helpful. Guess what's the first line of the Agile Manifesto? Individuals and interactions over processes and tools. So instead of thinking "Is ticket 4137 assigned to David or to Paula?", you will see the discussion of a real issue between your team.
The post goes on to give a detailed explanation of how to adapt Basecamp to an agile methodology (they use a mixture of Scrum and XP). Check it out.
