The objective of the prototyping systems development methodology is to rapidly build and rebuild an information system as the user and systems analyst learn from use of the prototype what features should be included min the evolving information system. Because the final prototype does not have to become the working system, where do you think would be an ideal location to develop a prototype: on a personal computer, department server, or enterprise server? Does your answer depend on any assumptions?
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?
Explain the importance of developing both logical and physical DFDs for systems? What advantage is there for drawing a logical DFD before a physical DFD for a new information system?
