The JAD process proceeds through a number of phases each succeeding phase considering different aspects of the system in ever increasing detail.

That is, it is not possible to deliver the system in small increments of functionality. JAD remains the best approach if the system must be conceived and delivered in its entirety.

Where JAD emphasises producing a requirements specification and optionally a prototype, Agile focusses on iterative development, where both requirements and the end software product evolve through regular collaboration between self-organizing cross-functional teams. Many of the principles originating from the JAD process have been incorporated into the more recent Agile development process. JAD was developed by Chuck Morris and Tony Crawford of IBM in 1977 and has since been proven successful on thousands of software projects across industry sectors and application boundaries. The outcome of a series of JAD sessions is a precise statement of user requirements. JAD can also be adapted to developing business processes that do not involve computer automation. The JAD approach leads to shorter development lifecycles and greater client satisfaction because it draws users and information systems analysts together to jointly design systems in facilitated group sessions. Joint Application Development (JAD) is a user requirements elicitation process that involves the system owner and end users in the design and development of an application through a succession of collaborative workshops called JAD sessions.
