Hi rajendra, "Agile" is the term when 17 people met at Snowbird in February,2001 used to express their common response to change in software development. With the agreements on four core values(described in the manifesto), the 17 people created Agile Alliance. The best introduction to Agile methodology is Martin Fowler's The New Methodology article. To be familiar with the four values, read The Agile Manifesto, and here is the interpretation and comments to the Manifesto by Martin Fowler and Jim Highsmith.
Creativity is allowing yourself to make mistakes. Art is knowing which ones to keep
Agile Alliance is like a club for people refusing that software delivering as a fuzy art. I totally agree that the goal in a project is to deliver a working software! and not making tonne of doc and Rose models! Are they all against Rational ?
Rajendra, I found myself these last 3 weeks describing "agile" software development as "cheating legally to win". When I tell people how to play agile, someone in the room almost always comments, "but that's cheating!" So "agile" is finding ways to deliver the software without having to go through some "standard" procedure, i.e., cheating. Hiring good programmers, putting them in a room together, forgiving most of the documentation, letting them talk to users and deliver code every few weeks - those are some of the cheating tactics that agile people use. As soon as we find more, we'll use them. Alistair
