The Agile Manifesto was written in 2001 by a group of software developers who wanted a more flexible, people-focused alternative to heavy, document-driven processes. Its short principles have since become standard reference material in software teams, training courses and agile coaching around the world. Numbered clips like this one circulate online as quick, shareable readings of individual phrases, making them easy to drop into lessons, slides and short videos without playing a full lecture. The fifth phrase remains useful because it captures a core agile idea in a single, memorable line.
