What is Agile Development

Agile methodologies are an alternative to waterfall or traditional software development practices. Agile methodologies usually have the following characteristics in common: they are iterative, collaborative, and they are built around self organizing teams.

The Agile Manifesto

In February 2001, seventeen software developers met at the Snowbird resort in Utah to discuss lightweight development methods. They published the Manifesto for Agile Software Development:

“We are uncovering better ways of developing
software by doing it and helping others do it.
Through this work we have come to value:

Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

That is, while there is value in the items on
the right, we value the items on the left more.”

The 10 Principles of the Agile Manifesto

The Agile Manifesto is based on ten principles[1]:

  1. Customer satisfaction by early and continuous delivery of valuable software.
  2. Welcome changing requirements, even in late development.
  3. Working software is delivered frequently (weeks rather than months).
  4. Close, daily cooperation between business people and developers.
  5. Projects are built around motivated individuals, who should be trusted.
  6. Face-to-face conversation is the best form of communication (co-location).
  7. Working software is the principal measure of progress.
  8. Sustainable development, able to maintain a constant pace.
  9. Continuous attention to technical excellence and good design.
  10. Simplicity—the art of maximizing the amount of work not done—is essential.
