Agile S. D.

Based on the Agile Alliance, Agile Software Development is a group of methods and practices which are based on values and principles stated in a document called Agile Manifesto.

The “Agile” term appeared in 2001 when some software developers gathered to discuss and shair the ideas that each individual had about software development.

The Agile Alliance developed 12 principles as follows:

  1. Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
  2. Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
  3. Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
  4. Business people and developers must work together daily throughout the project.
  5. Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done.
  6. The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
  7. Working software is the primary measure of progress.
  8. Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely.
  9. Continuous attention to technical excellence and good design enhances agility.
  10. Simplicity–the art of maximizing the amount of work not done–is essential.
  11. The best architectures, requirements, and designs emerge from self-organizing teams.
  12. At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.

My classmate Michelle Sagnelli also made a research on Agile regarding methodologies and the meaning Agile has as well.

There are many methodologies: Extreme Programming XP, Scrum, Crystal, Dynamic Systems Development Method DSDM, Lean Development, and Feature-Driven Development FDD. Each one of them has a unique characteristic; however, they all share the same approach to

incorporation of iteration and feedback that helps to improve and deliver a final software system.
