Using that process, the developers help the usersformulate problems and explore solution, and the users gain a feeling of involvement,ownership, and commitment to the success of the system.JAD (Joint ApplicationDevelopment) is also a methodology that involves the client or end user in thedesign and development of an application, through a succession of collaborativeworkshops called JAD sessions. Chuck Morris and Tony Crawford, both of IBM,developed JAD in the late 1970s and began teaching the approach throughworkshops in 1980,
