Due to the limited range of input and interaction among participants, few companies believe that a joint application development (JAD) group does not produce the best definition of a new system.

The belief that a joint application development (JAD) group does not produce the best definition of a new system is not universally held. JAD is designed to enhance communication and collaboration among stakeholders, which can lead to a more comprehensive and well-defined system. A group setting allows for diverse perspectives, immediate feedback, and collective problem-solving that can yield a more thorough understanding of the requirements.

In many cases, the strengths of JAD sessions, such as fostering innovation and resolving conflicts on the spot, outweigh concerns about the limited range of input. By bringing together users, stakeholders, and developers, JAD can effectively validate requirements, ensure that all relevant views are considered, and promote a shared vision of the system's capabilities. Consequently, companies that actively engage in JAD often find that it does lead to an improved definition of the new system they are developing.

The validity of the statement hinges on the context of company interactions and industry practices, but it is widely accepted that structured collaboration within a JAD framework tends to produce beneficial outcomes in system definition processes.
