Agile Manifesto

A foundational document for agile software development, written in 2001 by seventeen software practitioners at a Utah ski resort. The Manifesto contains four core values: individuals and interactions over processes and tools; working software over comprehensive documentation; customer collaboration over contract negotiation; and responding to change over following a plan. It is complemented by twelve principles that elaborate on these values. The Agile Manifesto does not prescribe specific frameworks or practices — instead it articulates shared values that underpin Scrum, Kanban, XP, and other agile methods. It remains the most influential document in modern software development methodology.
