Scrum Methodology
Scrum is an Agile development methodology focused on design, building, testing and delivering software. Basically, Scrum can also be applied to other goals and results than working software. In practice, it is mostly about software. There are of course more Agile methods such as Lean, XP (Extreme Programming) and older versions such as DSDM (Dynamic Systems Development Method) and RAD (Rapid Application Development, but Scrum has become the most popular Agile methodology. That's probably because of its simplicity and the successful results achieved with Scrum.
Scrum provides a small set of rules that create just enough structure for teams to be able to focus their innovation on solving what might otherwise be an insurmountable challenge.
JAD Methodology
JAD is a requirements-definition and user-interface design methodology in which end-users, executives, and developers attend intense off-site meetings to work out a system's details. The Joint Application Development (JAD) methodology aims to involve the client in the design and development of an application. This is accomplished through a series of collaborative workshops called JAD sessions. Two employees of IBM, Chuck Morris and Tony Crawford, developed the JAD methodology.
