Teams that work within the Scrum framework do not have traditional roles.  There are no set programmers, designers, QA, etc.  Everyone who is on the team, works as one to complete the items they have agreed to complete during a set time period (sprint).  For the most part, scrum teams have a true “team” feeling because they are all working towards a common goal. 

According to the Scrum Alliance, the Scrum team meets the following criteria:

Scrum teams participate in the daily scrum together, with their Scrum Master.  They also are a working machine when it comes to products that are on their Sprint backlog.  They will make sure that what they have committed to is finished at all costs, no matter what obstacles may lay in their path.  This , in essence, is the beauty of Scrum, because what is committed to be done, is done by the team.
