Differing greatly from the traditional "waterfall" or "relay" approach to project management methodology, Scrum emphasizes the importance of a cross-functional team that pushes forward together to a collective goal - the project success. Implementing such tactics as "Daily Scrums" in which all members of the team are held accountable for their accomplishments, current tasks and potential obstacles, Scrum attempts to create a real "team" amongst all members where all individuals most move forward together, as occurs within a Scrum on the Rugby Field from which the term was adopted.
