For the new PC described in Question 6, develop ranked lists of your requirements and constraints as displayed in Figure 7-19. Display the requirements and constraints, along with the three alternatives, as done in Figure 7-19, and note how each alternative is rated on each requirement and constraint. Calculate scores for each alternative on each criterion and compute total scores. Which alternative has the highest score? Why? Does this choice fit with your selection in the previous question? Why or why not?

Data from Question 6.

Consider the purchase of a new PC to be used by you at your work (or by you at a job that you would like to have). Describe in detail three alternatives for this new PC that represent the low, middle, and high points of a continuum of potential solutions. Be sure that the low-end PC meets at least your minimum requirements and the highend PC is at least within a reasonable budget. At this point, without quantitative analysis, which alternative would you choose?
