Waterfall vs. Agile Methodology

Most software development projects apply either the Waterfall or Agile methodology. A development methodology is the procidure used by an engineering team in order to create a desired product. The Waterfall methodology represents the traditional approach, where the development process is conducted in a linear series of events. On its way toward the conclusion the progress flows continously through the phases of a project (analysis, design, development,testing) like a waterfall. The entire project is planned in advance. Agile is a more recently developed software development methodology, where the linear approach is replaced by an incremental, iterative one. Instead of planning the whole project in advance, Agile enables the adaption of requirements during the divers iterations. This artice provides an introduction of each methodology, a comparison and examples of use, in order to facilitate the decision whether Agile or Waterfall is more suitable for the next project.
