204. Growing State University (GSU) is planning to change from its batch-oriented grade reporting system
(BGRS) to a new, online grade reporting system (OGRS). The partial organization chart for GSU appears in TB
Figure 17.1. TB Figure TB 17.2 is reproduced from Chapter 17 and shows three possible system
implementation approaches.
Required:
Demonstrate your understanding of the three approaches in TB Figure 17.2 by constructing an example from
the GSU scenario to explain (in one paragraph for each) how each approach might be applied at GSU. Be
specific as to which of GSU’s organizational units would convert to OGRS and when. Assume that time X in
TB Figure 17.2 is the start of the 20X8 fall semester. Make and state any other assumptions you feel are
205. TB Figure 17.3 is taken from the text figure showing the systems selection task and documents.
Required:
Explode bubble 3.0 Systems Selection into a Level 1 DFD. The DFD should include the items listed below. The
data flows for available hardware and physical requirements are listed twice because these data flows will each
appear twice in the Level 1 DFD.
206. Figure TB 17.5 is the DFD of the systems development life cycle as presented in the text.
Required:
Explode bubble 4.0 Structured Systems Design into a Level 1 DFD. All of the process bubbles and data flows
are presented below. The data flows for implementation plan and budget and logical specification are listed
twice because these data flows will appear twice in the Level 1 DFD.
