Agile Process

• Agile software process addresses few assumptions
  • Difficulty in predicting changes of requirements and customer priorities.

  • Analysis, design, construction and testing are not as predictable as we might like.

• Requires customer feedback

• Welcome changing requirements
• Deliver working software frequently
• Business people and developers must work together
• Build projects around motivated individuals
• Emphasize face-to-face conversation

• Continuous attention to technical excellence and good design
• Simplicity – the art of maximizing the amount of work done
• The best designs emerge from self-organizing teams
• The team tunes and adjusts its behavior to become more effective

Agile Process Models

• Extreme Programming (XP)
• Adaptive Software Development (ASD)
• Dynamic Systems Development Method (DSDM)
• Scrum
• Feature Driven Development (FDD)
• Crystal
• Agile Modelling (AM)
