MIS 306 – Fall 2021 Exam 2 Review Topics Covered: Class 8: Planning Phase Class 9: Analysis Phase and Requirements Gathering Class 10: Feasibility Analysis Class 11: Process Modeling Class 12: Moving into Design Phase Class 13: Cloud Services Class 8: Planning Phase • • • • •

•

Know the 4 different levels of “planning” and the distinctions among them. For example, who does the planning for the IS Architecture level and what is the purpose or primary goal of that level? Know what executives mean when they say “our biggest challenge is aligning IS with strategy” Know what a “siloed” company is, why it’s a problem, and why enterprise integration is a solution to that problem. Know what “enterprise integration” means at the technical level. Technology levels means things like the hardware and software of a system. Know the differences among the 6 generic enterprise strategies. Be able to match an application that I give to the best strategy. For example, if I say “implement an online ordering application so the cost of data entry is moved from company staff to customers” you would choose “Cost Leader / Low Cost producer.” The key is to pay attention to the reason I give for the application, in this case “reduce our costs”. If I had said, “in order to give the customers a much more personalized experience than any other competitor offers” you would choose Differentiation. This means you’ll need to know those strategies well. Know what each of these are, and how they differ: enterprise, business area, business process, business application. Think of how they relate in the hierarchy of systems.

Class 9: Analysis Phase • What is the difference between a functional requirement and a nonfunctional requirement? Be able to identify examples of both. • What is the difference between a business requirement and a user requirement? Be able to identify examples of both. • Be able to draw and define the entire SDLC you learned in Class 6 (PADIM). I may ask you again. • What is the value of separating the Analysis and Design phases? That is, why don’t we combine the two phases and just get to the Implementation faster? • Be able to explain the activities and outcomes in the 3 steps of the Analysis phase (Survey, Study, Define) and how they differ from each other. • For requirements elicitation, why would you choose any of these four methods over another: interview, questionnaire, observation, JAD? Think in terms of access, broad vs deep information, timing, cost, credibility, and kind of information. • Know how to use the causal chain in identifying root causes of problems in systems analysis.

Class 10: Feasibility Analysis • Know these types of feasibility that you should test at the end of each phase: Economic/Financial, Operational/Organizational, Schedule, Technical. Know what they are and what they look at, and how they are different from each other. • Know how to do an Expected Value Calculation to take an intangible benefit/cost, such as customer satisfaction, and turn it into a tangible benefit, like dollar revenue/cost. Assume you will be given the scenarios and probabilities, but you have to figure out the rest, so think about that table. • Know how you would use your result from that Expected Value Calculation in an ROI or BEA calculation. • Know the difference between ROI and BEA, and how you would calculate both. • Know the formula for ROI. • What is NPV? Is NPV a metric itself? Or a technique used in preparing metrics for analysis? Class 11: Process Modeling • Be able to draw current logical context, decomposition, and Level-0 DFDs for a short process description, similar to Green Acres Real Estate. • Know the difference between current and proposed systems, and between logical and physical process models. • Be able to distinguish these: a context diagram, a functional decomposition diagram, a Level 0 diagram, and a Level-1 diagram. • Know most of the Gane and Sarson rules of correct process modeling syntax. • Know what “balancing” means, among DFDs. Class 12: Moving Into Design • What are the main differences between analyzing a system (Analysis Phase) and designing a system (Design Phase)? Be able to distinguish the two in the Waterfall model. What different outcomes and deliverables do each produce? • Be able to explain the approaches to acquiring systems - make, buy, subscribe (rent) – and 2 reasons why you would choose one approach over the other based on your business or technical needs. • Be able to explain what the difference between in-house development and outsourced development is. • Be able to discuss the client/server architecture including using Data, Applications, and Interface as the three resources you can allocate. Why would a company deploy a “Fat client” over a “Thin Client”, or vice-versa? • Be able to identify a given device as a client or a server Class 13: Cloud Services • Be able to describe the 3 major components of a Cloud service: SaaS, PaaS, IaaS. • Be able to define and give an example of virtualization. • What are 3 business benefits of migrating on premises applications to the Cloud, and how or why are these benefits? • What are 3 technical benefits of migrating on premises applications to the Cloud, and how or why are these benefits? • What are the main differences between a Public Cloud, a Private Cloud, and a Hybrid Cloud? • Know what virtualization means, especially desktop virtualization, and what business benefits it gives a company. • Name 3 major commercial providers of Cloud Services. For example, one of them is Amazon Web Services (AWS). 2
