The use of structured language to describe processes that are not included in a systems analysis is something that should be explored, despite the fact that it is not required.
In order to quickly create and rebuild an information system, the user and systems analyst must learn from the prototype what elements should be included in the expanding information system. Because the final prototype will not be used, where should it be developed: on a personal computer, department server, or enterprise server? Is your response predicated?
Methods from the past, present, and future of analyzing systems to determine their needs are compared and contrasted. Does it ever make sense to use any of the examined tactics, and what are the drawbacks of doing so?
