Agile has roots in Lean and object-oriented thinking, which is many decades old. The Harvard Business Review article “The New New Product Development Game” from 1986 helped popularize lean thinking in the West and intensified these conversations about a better way to do work. Along with other inspirations, this began the development of numerous frameworks such as Extreme Programming, SCRUM, DSDM, Adaptive Software Development, Crystal, Feature-Driven Development, Pragmatic Programming, and others – sympathetic to the need for an alternative to documentation driven, heavyweight software development processes that were not working.
On February 11-13, 2001, at The Lodge at Snowbird ski resort in the Wasatch mountains of Utah, seventeen people (from these various frameworks) met to talk, ski, relax, and try to find common ground—and of course, to eat. What emerged was the Agile ‘Software Development’ Manifesto.
