Thus, fancy systems are of little interest to them unless they provide no pain-and no pain to these users means having a system that makes their job easier. The next area to understand about users is their level. By level, I mean their understanding of computers. There are three levels of users: 1. 2. 3. Knowledgeable: The determination of knowledge can be tricky and is certainly based on someone's opinion. I define knowledge in reference to experience. " A user who has been through the development of a new system can therefore be defined as "knowledgeable" within this context.

This will typically involve a discussion of the minimum acceptance testing to be validated against the product and the mechanism for testing in the field. Phase XI: Finalize Specification Document After review sessions are completed, the Facilitator will prepare the final document to be submitted for approval and eventual implementation. If prototypes are used, the screens and reports can be moved into the software development (construction) phase. There should also be post-JAD reviews with the development teams to clarify information supplied in the final system specification document.
