Base of Agile Software Development

Rapid Software Development

• Rapid development and delivery is now often the most important requirement for software systems
  • Business operate in a fast: changing requirements, and it is practically impossible to produce a set of stable software requirements.
  • Software has to evolve quickly to reflect changing business needs.
• Plan-driven development is essential for some types of system but does not meet these business needs.
• Agile development methods emerged in the last 1990s, whose aim was to radically reduce the delivery time for working software systems.

Features of Agile Development

• Program specification, design and implementation are inter-leaved.
• The system is developed as a series of versions or increments with stakeholders involved in version specification and evaluation.
• Frequent delivery of new versions for evaluation.
• Extensive tool support used to support development.
• Minimal documentation: focus on working code.
