Who is involved in a JAD?

Sponsor - this is the executive who charters the project, the system owner. They must be high enough in the organization to be able to make decisions and provide the necessary resources and support for the project. 

Business Users - the intended users of the system being designed. They are here because of their business expertise. There are two kinds of Business Users; Real End Users and Big Picture Users.

Real End Users will have to use the new system to do their jobs. Big Picture Users understand the standards and methodologies of the business functions. It is important to have both types of users, if you only have Big Picture Users you will end up with a great theoretical model of how things should work, but it may not work in practice, if you just have Real End Users, you will get a good system for today, but it may not work a year or two down the road. 

Systems Analysts - Provide non-technical explanations that help other JAD members understand and fully utilize the technology available. Monitor design for ease of use/maintenance and adherence to standards. Provide Hardware/software development.
