Agile software development is based on an incremental, iterative approach. Instead of detailed planning at the beginning of the project, agile methodologies allow a change in requirements over time and encourage constant feedback from the end users. Cross-functional teams work on iterations of a product over a period, and this work is organized into a backlog that is prioritized based on business or customer value. The goal of each iteration is to produce a working product. While the waterfall method is highly logical, it has low process efficiency. Agile development is of short iteration with a development cycle of one to four weeks and follows incremental releases. With agile, the idea is to do a little bit of everything in every cycle (plan, test, design, and build), followed by customer feedback. Agile refers to any process that aligns with the concepts of the agile manifesto.
