Agile Method

The Agile method attempts to bring quick, constant delivery of product to the customer. Whereas traditional methodologies such as the Waterfall method or other linear processes require detailed requirements that are defined at the beginning where the end product is what defined in the beginning. With Agile there is no well-defined end product at the onset. In Agile there is still a disciplined prioritization process, but the non-static requirements, flexibility, constant change, and regular communication approach this as part of the culture and process.
