Agile

1. Early implementations of agile methods include Rational Unified Process (1994), Scrum (1995), Crystal Clear, Extreme Programming (1996), Adaptive Software Development, Feature Driven Development (1997), and Dynamic Systems Development Method(DSDM) (1995).These are now collectively referred to as agile methodologies, after the Agile Manifesto was published in 2001.
   
2. Jim Highsmith: The Agile movement is not anti-methodology.
3. Yet,there are approaches providing full coverage over the development life cycle (e.g. DSDM, IBM RUP), while most of them are suitable from the requirements specification phase on (FDD, for example).
   
4. Agile development is supported by a bundle of concrete practices suggested by the agile methods, covering areas like requirements, design, modeling, coding, testing, project management, process, quality, etc.
   
5. In The Elements of Scrum the Product owner "... is usually the most demanding role on a scrum team."
