What is Agile?
The ability to create and respond to change in order to succeed in an uncertain and turbulent environment.
In the late 1990’s, several methodologies began to gain increasing public attention, each having a different combination of old and new ideas. These methodologies emphasized close collaboration between the development team and business stakeholders; frequent delivery of business value, tight, self-organizing teams; and smart ways to craft, confirm, and deliver code.
The term "Agile" was applied to this collection of methodologies in early 2001 when 17 software development practitioners gathered in Snowbird, Utah to discuss their shared ideas and various approaches to software development. This joint collection of values and principles was expressed in the Manifesto for Agile Software Development and the corresponding twelve principles.
The Agile Alliance was formed shortly after this gathering to encourage practitioners to further explore and share ideas and experiences.
