Discuss your observations about the strengths and weaknesses of DUB 5’s order processing system

Our Case Study 1 can be found on page 78 of our textbook (Case 3-1 “Dub 5”). This case builds on material presented in the Chapters 1 and 2, combined with the discussion about systems documentation techniques in Chapter 3 (especially, Data Flow Diagrams or DFD). As you prepare to complete the case, in addition to reading chapters 1-2, read also the DFD discussion on pages 50-54, which begins our reading assignment for week 2. I suggest that you organize your Case Study as follows:

1) Summary of the Case What is the purpose of the case? For example, in this case, provide a DFD view of the order and credit review process for DUB 5.

2) Level 0 DFD for Order processing Using the written description of the DUB 5 process in the case, and the rough diagram at the bottom of the case, create your Level 0 DFD. You can submit a DFD that is hand-drawn and scanned, use Excel or Visio, or another program.

3) Level 1 DFD for the Credit Review Process Going down one level in the DFD, focus on the credit review process only and create a DFD for this process. Again, you can submit a hand-drawn DFD or use an automated program. Your choice.

4) Observations About the Processes

Discuss your observations about the strengths and weaknesses of DUB 5’s order processing system.
