Agile development is an effect of the negative reaction against the commonly practiced software development models of the olden days, namely the waterfall model. It started becoming a popular and practical mode of development approach since the mid 1990's. Agile development came into existence due to the fact that theoretical approach of the waterfall model came out to be quite different from the practical methodologies followed by the developers to successfully design and develop any software solution. During initial days of programming, agile development methods have been referred to as “light weight” methods. In the year 2001 the agile community adopted the name “agile methods.” In the past there have been several agile development methods available to the software industry and each of these are having its own significance and importance to its followers and the community is consistently working towards effective utilization of these methods by the software development world.
