Consider the purchase of a new PC to be utilized by you at your work (or by you at a job that you would like to have). Define in detail three alternatives for this new PC that represents the low, middle as well as high points of a continuum of potential solutions. Be definite that the low-end PC meets at least your minimum requirements as well as the high-end PC is at least within a reasonable budget. At this point without quantitative study, which another would you choose?
