Scrum: a lightweight agile method for software development, named after the Scrum in Rugby, which is a way to restart a game after a minor infringement. This methodology was first tried in 1993 at Easel Corp., by Jeff Sutherland and John Scumniotales to build an object-oriented design and analysis (OOAD) tool which incorporated round-trip engineering. They needed a means of rapid application development, where product requirements could be translated into working code easily.
