The Agile project management Declaration of Interdependence was written in early 2005 by a group of 15 project leaders as a supplement to The Agile Manifesto. It enumerates six management values needed to reinforce an Agile development mentality, particularly when managing complex, uncertain projects.

The declaration highlights that project teams, customers, and other stakeholders are interdependent and connected and must recognize this to be successful. The values themselves are also interdependent.
