Agiles walk from the Past..

The modern definition of agile software development evolved in the mid-1990s as part of a reactionagainst "heavyweight" methods, perceived to be typified by a heavily regulated, regimented,micro-managed use of the waterfall model of development. The processes originating from this use of thewaterfall model were seen as bureaucratic, slow, demeaning, and inconsistent with the ways thatsoftware developers actually perform effective work. A case can be made that agile and iterativedevelopmentmethods mark a return to development practice from early in the history of softwaredevelopment. [1] Initially, agile methods were called "lightweight methods.

An adaptive software development process was introduced in a paper by Edmonds (1974). [2] Notableearly Agile methods include Scrum (1995), Crystal Clear, Extreme Programming (1996), AdaptiveSoftware Development, Feature Driven Development, and Dynamic Systems Development Method(DSDM) (1995). These are now typically referred to as Agile Methodologies, after the AgileManifestopublished in 2001.

In 2001, 17 prominent figures[3] in the field ofagile development (then called "light-weight methods")came together at the Snowbird ski resort in Utah to discuss ways of creating software in a lighter,

faster, more people-centric way. They coined the terms "Agile Software Development" and "agilemethods", and they created the Agile Manifesto, widely regarded as the canonical definition ofagile development and accompanying agile principles. Later, some of these people formed TheAgile Alliance,[4] a non-profit organization that promotes agile development.

thinks about it and says, "Why don't we call it

Should be fixed as and when you find it.

Might have 1-2 more sprints to fix critical

bugs.

They measure their work with

Burn down charts

24/28

Then they have Sprint Review

Meeting

Present the completed work to the
