Joint Application Development (JAD) is a software development approach where business users and engineers work together to build a computer system. JAD uses prototyping techniques for validation and requires a team of business users, communications experts, technical writers, and developers. JAD sessions should follow a strict schedule and timeline, organized around specific functional areas, and include breaks. The main benefits of JAD are speed and quality, with a full session completed in a few weeks and a usable prototype transferred to the production team for faster development.
Joint application development (JAD) is a software development approach in which business users and computer engineers work together to build a computer system. This joint project team is typically sequestered for several weeks during the system design phase. Using a JAD approach produces better software because users are active participants in building the system.
Gathering system requirements is one of the most important steps in building computer software. The joint application development approach enforces active participation during requirements meetings, which makes meetings more productive. This is achieved by allowing users to interact with a daily prototyped system.
Prototyping an idea is a proven method for validating the requirements for a new business product. This is often done in manufacturing companies before investing in a new product line. The prototype is typically a smaller model that represents the ideas of the creators of the new product. Joint application development uses these prototyping techniques to demonstrate system software ideas.
Rapid Application Development (RAD) was a popular software prototyping approach used in the mid-1990s. It was also based on the idea of building rapid prototypes for validation purposes. Joint application development evolved from this approach by integrating the prototype design with formal documentation.
One of the keys to a successful joint application development project is assembling a team. JAD requires four groups of participants to be highly engaged and motivated during the prototype sessions. This team includes business users, communications experts, technical writers and software developers.
Joint application development sessions should follow a strict schedule and timeline. This typically includes idea capture, prototyping, and requirements validation. Each meeting should be managed by a facilitator who understands the expected outcome of the meetings.
JAD sessions should be organized around the specific functional areas of the new product. This approach is typical of large product development efforts. It helps keep the team focused and engaged on a specific idea. Sessions should include adequate breaks and refreshments to ensure the team remains upbeat and engaged.
One of the main benefits of using the joint application development approach is speed and quality. A full JAD session should be completed in a few weeks and includes a usable prototype. This prototype can be transferred to the production team where development can begin. This is typically a faster process than other development techniques.
