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.

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?

C HAPTER 6 Object Modeling

Q UESTIONS What is Structured Analysis & Design? What is Object Oriented Analysis & Design?

O BJECT M ODELING Based on objects Object has attributes and methods Can create instances of objects Question: If our object was a car… What would be attributes? What would be methods? What would be instances?
