The Board is a tool for scheduling project teams. Add projects, add people, then drag the people around from project to project and week to week. It is open source, available under the MIT license.
The Board is inspired by the magnet board used to schedule the ballpersons staff at the US Open, where I worked for several summers during college. I’m not sure who originally invented it, but it’s been in use for years at the Open, and is one of the most effective team planning tools I’ve every seen.
