Rapid Application Development (RAD)
Explanation:
Rapid Application Development (RAD) describes a method of software development which heavily emphasises rapid prototyping and iterative delivery. The RAD model is, therefore, a sharp alternative to the typical waterfall development model, which often focuses largely on planning and sequential design practices.
Joint Application Development (JAD) is a development methodology system originally used for designing a computer-based system, but can be applied to any development process. It involves continuous interaction with the users and different designers of the system in development. JAD centres around a workshop session that is structured and focused.
