How different are projects managed with Agile?

1. Roles
   
   The roles on an Agile team blur in a sense that people do whatever it takes to make the project successful, regardless of title or role.
   
   
   
2. Continuous Activities
   
   On an Agile team, the analysis, code design and testing are activities that are executed in a continuous basis.
   
   
   
3. One Team
   
   All team members are responsible of the quality, there is not a dedicated entity such as a QA department. Whether while doing analysis, developing code, testing or managing the project.
