Agile development methods emerged in the late 1990s whose aim was to radically reduce the delivery time for working software systems 4 CuuDuongThanCong.com https fb.com tailieudientucntt 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 e.g. automated testing tools used to support development. Minimal documentation focus on working code 5 CuuDuongThanCong.com https fb.com tailieudientucntt Plan-driven and agile development Plan-based development Requirements Requirements Design and engineering specification implementation Requirements change requests Agile development Requirements Design and engineering implementation 6 CuuDuongThanCong.com https fb.com tailieudientucntt Plan-driven and agile development Plan-driven development p A plan-driven approach to software engineering is based around separate development stages with the outputs to be produced .
