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 centers around a workshop
session that is structured and focused. Participants of these sessions would
typically include a facilitator, end users, developers, observers, mediators and
experts. JAD allows for a faster
development process and minimizes errors at the same time. JAD also improves the
quality of the final product by focusing on the up-front portion of the
development lifecycle, thus reducing the likelihood of errors that are expensive
to correct later on.
The opposite of JAD is
RAD (Rapid
Application Development)
