• Changes in user requirements can increase the cost and time estimate of a project. As a project manager, what measures would you take to keep the project on track despite changes in user requirements? • How would you go about determining how many use-case models you will need to create to specify the functional requirements for your development project? How would you go about determining what requirement specifications will require usecase models, declarative requirements, or both? It is difficult to determine the level of detail in which a use case description should be written. What makes the level of detail low or high? What factors would you consider to determine the appropriate level of detail for a use case description? • An OO analysis model represents classes of objects about which an enterprise wishes to store information corresponding to attributes, and behaviors, or operations. Discuss the place of OOA in the overall systems analysis and design process. Describe a training plan to train analysts on class modeling. At what point(s) in the development process should this training be conducted? Why? • In the unified modeling language (UML), usecase modeling captures different aspects of the operational workflows of a system. How would you extend use-case models that you created in the requirements phase, to usecase models that apply to the design phase? Prepare a list containing at least 10 criteria for evaluating computer hardware and system software. The method for evaluating alternatives called weighting and scoring implies that the total utility of an alternative is the product of the weights of each criterion times the weight of the criterion for the alternative. What assumptions are characteristic of this method for evaluating alternavtives? • Discuss the advantages of the componentbased design modeling approach, and how you would approach it in the design phase Analyze the benefits and limitations of the use-case diagram, OOD class diagram, sequence diagram, activity diagram, and state diagram in the design phase of your system development process. Discuss how to determine to use some, or all these tools in your design phase.
