The Agile Manifesto

The Agile Manifesto was written in February of 2001, at a summit of seventeen independent-minded practitioners of several programming methodologies. The participants didn't agree about much, but they found consensus around four main values.  

Supplementing the Manifesto, the Twelve Principles further explicate what it is to be Agile.

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.
