Agile requirements
* A developer involved in Agile projects must have the "Agile mindset" which implies:
* a positive attitude and pragmatism
* thirst for knowledge: Agile is about learning and adapting. Knowledge sharing is key to success.
* The goal of team success: Agile is about the success of the team, no individual success or heroic behavior. It is more important for the team to succeed than for the individual to have completed his/her tasks.
* There is no failure, only feedback: Agile is about taking everything as lessons, adjusting actions based on the feedback, resulting in continuous improvement.
* Beyond the roles: Agile teams are cross-functional. All required disciplines are represented in the team (analysis, development, testing, ...). However, although team members have a primary role representing a discipline, they are expected to take on other roles and contribute to other disciplines whenever it helps towards reaching the sprint goal.
