1. Joint application development (JAD) JAD was originally developed for internal use at IBM in the late 1970s. Its success there prompted IBM to make it available to clients JAD became quite popular because of its apparent usefulness in addressing several of the shortcomings of the interviewing tech- nique and the potential to reduce the cycle time for systems development [1,8,39,46]. Early adopters were also fascinated by JAD's projected capability to assist with the de- velopment of team rapport. In addition, JAD is compatible with several developmentExplanation / Answer
Joint Application Development (JAD) is a method of system development life cycle which attaches great importance to the user involvement through out the development process. It was originally developed for internal use at IBM in the late 1970s. JAD is known by several other names such as joint application review, facilitated workshops, accelerated designs, facilitated meetings, interactive JAD, joint sessions, modeling sessions, team sessions, team analysis, and user centered design. JAD is employed in any decision-making context where facilitated interactions are required. It plays a huge role in eliciting the necessary requirements for the development process and reduce cycle time for system development.
The facilitator is responsible for impartially guiding the session towards the attainment of the objectives. The facilitator makes sure that the available time is used productively and attempts to obtain maximum team participation. The facilitator should be multi-skilled, exhibit leadership and management, interpersonal relationship, business and system analysis, and communication. Thus excellent facilitation can lead to minimized dysfunctional behavior, group productivity, and resolved conflicts.
The five stages of JAD are:-
The JAD workshop is a session of interactions among the facilitator, executive sponsor, the project manager, system professionals, user/managers and other system users, who are domain experts and provide and make decisions. A scribe(note-taker) present at the event records and documents the deliberations but does not participate in the discussions.
JAD workshops are supported by a variety of visual aids including flip charts and post-it notes that fill up the walls of the meeting room with agenda items, requirements information, data and process models, and open items postponed for further discussions. Technology aids like overhead projectors, electronic white boards, graphics software, and computer aided software engineering (CASE) tools are also used.
The primary objective of JAD is to achieve synergy by increasing interaction, combining the knowledge of the group, and thus there is immense signification to the communication aspects. This facilitates more thorough and precise specifications, shorten schedules, improve system quality and remove conflicting and ambiguous requirements.
