What is JAD in IT?
Joint application design ( JAD) is a process used in the life cycle area of the dynamic systems development method (DSDM) to collect business requirements while developing new information systems for a company. "The JAD process also includes approaches for enhancing user participation, expediting development, and improving the quality of specifications." It consists of a workshop where " knowledge workers and IT specialists meet, sometimes for several days, to define and review the business requirements for the system." The attendees include high level management officials who will ensure the product provides the needed reports and information at the end. This acts as "a management process which allows Corporate Information Services (IS) departments to work more effectively with users in a shorter time frame".
What is JAD in computer science?
In 1985, Gary Rush wrote about JAD and its derivations – Facilitated Application Specification Techniques (FAST) – in Computerworld. Originally, JAD was designed to bring system developers and users of varying backgrounds and opinions together in a productive as well as creative environment.
What is JAD workshop?
Through JAD workshops the knowledge workers and IT specialists are able to resolve any difficulties or differences between the two parties regarding the new information system. The workshop follows a detailed agenda in order to guarantee that all uncertainties between parties are covered and to help prevent any miscommunications. Miscommunications can carry far more serious repercussions if not addressed until later on in the process. (See below for Key Participants and Key Steps to an Effective JAD). In the end, this process will result in a new information system that is feasible and appealing to both the designers and end users.

What is JAD in project management?
The JAD approach is to allow project executives and representatives of the customer to identify and appoint a trained facilitator whose role is to support project delivery. While the facilitator helps in driving the projects, key decisions have to be taken by the executive sponsors. Other key stakeholders include the subject-matter expert who is responsible for turning the customer's requirements into a technology-powered solution, and the documentation expert, whose role is to clarify the points of discussion and document them effectively during the JAD sessions. The facilitator serves as the central link between different stakeholders for the purpose of initializing and driving the JAD workshops and sessions.

JAD is a modern approach for gathering development project requirements through one or more workshops that bring together all the stakeholders in one location . It has proven to be effective in accelerating the development of information technology systems through the use of customer involvement and group dynamics to accurately interpret the user's view of the business need. Major stakeholders at the heart of JAD methodology include the executive sponsor as the ultimate decision maker, the facilitator who coordinates and plans the collaborative sessions, and the scribe whose role is to ensure that key discussions during the sessions are well documented.
What is JAD in Agile?
JAD is more prevalent in Agile delivery environments, in which software products are developed and shipped in short cycles based on agreements between the commercial and technical stakeholders on what is known as the minimum viable product (MVP). In other words, anytime there is a need for the business representatives and the technology teams to deliberate and develop synergy on issues around product development or testing requirements, a JAD session becomes necessary. In what is largely dependent on the size of the project in development, the session may last anywhere from a few hours to a day or even weeks, in some cases.

If JAD session organizers do not study the elements of the system being evaluated, an incorrect problem could be addressed, incorrect people could be invited to participate, and inadequate problem-solving resources could be used.
• JAD workshop participants should include employees able to provide input on most, if not all, of the pertinent areas of the problem. This is …
