1.C. N. Itall has been a systems analyst for Tun-L-Vision Corporation for many years. When you came on board as part of the systems analysis team and suggested prototyping as part of the SDLC for a current project, C. N. said, "Sure, but you can't pay any attention to what users say. They have no idea what they want. I'll prototype, but I'm not 'observing' any users."
a. As tactfully as possible, so as not to upset C. N. Itall, make a list of the reasons that support the importance of observing user reactions, suggestions, and innovations in the prototyping process.
b. In a paragraph, describe what might happen if part of a system is prototyped and no user feedback about it is incorporated into the successive system.
2Harold, a district manager for the multioutlet chain of Sprocket's Gifts, thinks that building a prototype can mean only one thing: a nonworking scale model. He also believes that this way is too cumbersome to prototype information systems and thus is reluctant to do so.
a. Briefly (in two or three paragraphs) compare and contrast the other three kinds of prototyping that are possible so that Harold has an understanding of what prototyping can mean.
b. Harold has an option of implementing one system, trying it, and then having it installed in five other Sprocket locations if it is successful. Name a type of prototyping that would fit well with this approach, and in a paragraph defend your choice.
3."I've got the idea of the century!" proclaims Bea Kwicke, a new systems analyst with your systems group. "Let's skip all this SDLC garbage and just prototype everything. Our projects will go a lot more quickly, we'll save time and money, and all the users will feel as if we're paying attention to them instead of going away for months on end and not talking to them."
a. List the reasons you (as a member of the same team as Bea) would give Bea to dissuade her from trying to scrap the SDLC and prototype every project.
b. Bea is pretty disappointed with what you have said. To encourage her, use a paragraph to explain the situations you think would lend themselves to prototyping.
4.The following remark was overheard at a meeting between managers and a systems analysis team at the Fence-Me-In fencing company: "You told us the prototype would be finished three weeks ago.
We're still waiting for it!"
a. In a paragraph, comment on the importance of rapid delivery of a portion of a prototyped information system.
b. List three elements of the prototyping process that must be controlled to ensure prompt delivery
c. What are some elements of the prototyping process that are difficult to manage? List them
