Agile Manifesto
Noun · Hacker Culture
Definitions
A 2001 declaration by seventeen software developers — including Kent Beck, Martin Fowler, and Robert C. Martin — establishing four core values (individuals over processes, working software over documentation, customer collaboration over contracts, responding to change over following a plan) and twelve principles that became the foundation for Scrum, Kanban, XP, and other iterative development methodologies.
In plain English: A famous statement of principles from 2001 that argues software should be built in small, flexible steps with close collaboration, rather than following a rigid master plan.
Example: "The manifesto says 'working software over comprehensive documentation,' not 'no documentation at all' — but good luck explaining that to management."
