Back in 1970, Chuck Morris and Tony Crawford from IBM developed the JAD approach. This approach incorporates one or more workshops after the functional design has been created and before the software development begins.

Participants in these workshops include business representatives, functional consultants, programmers, QA specialists, and the project sponsor.

During these workshops, the functional consultant also acts as the facilitator. They present the developed functional design in a way that everyone can understand. This design includes the business’s expectations, details about the business logic, communication between various functionalities, and connections or impacts on other systems.
