5. U NIT 5: D ISCUSSION Q UESTIONS DQ1: Project Risk Projects pose many avenues of risk for organizations. Systems analysts are tasked with helping to mitigate that risk by providing the customer with the best options that meet their needs but do not take advantage of their lack of specialization regarding the system being implemented. Search the Internet and find a resource that describes what causes IT projects to fail and list at least one of those reasons and how the systems analyst can help mitigate that risk.

6. U NIT 5: D ISCUSSION Q UESTIONS DQ2: Structured versus Object Oriented Analysis What is the definition of the structured analysis as it pertains to the SDLC? What is the definition of object oriented analysis as it pertains to SDLC? Given, both of the above definitions, what are the real differences? When should each be used? Are they mutually exclusive processes or do they go hand in hand?

Midterm Project is due Tuesday, April 24 Midterm Project (Unit 5) Based on Willowbrook School scenario Write mission statement List 6 business processes and person responsible Develop business case for proposed TIMS system List system requirements for new TIMS system Write analysis of diagrams Create decision tree for determining discounts Peer review of all group members

8. B USINESS C ASE Reasons or justification for the proposed system Answer the following questions (in paragraph format) Why are we doing this project? How does this solution address the problem? How much will cost and how long will it take? What are the risks of this project? What are the risks of not doing this project? How will we measure success? What sources of funding are available for this project? Convince me the problem is real and a new system will solve that problem!
