Scrum: transparency, inspection and adaptation of the project process
Managing a project using the Scrum method

Scrum means scrum in rugby. It uses the values and spirit of rugby, and adapts them to development projects. Like the pack when carrying a rugby ball, the development team works collectively, united towards a precise objective. Like a scrum-half, the ScrumMaster spurs on team members, repositioning them in the right direction and setting the tempo to ensure the project's success."

Ken Schwaber most often describes Scrum as a framework.
