Therac 25 and Video
Requirement is 1 page and when you do the questions just write the numbers for the answers.
1. If you were a judge who had to assign responsibility in the Therac-25 case, how much responsibility would you assign to the programmer, the manufacturer, and the hospital or clinic using the machine? Use percentages. Would you assign responsibility to any party not listed here? Justify your reasoning.
2. Choose a non-computer activity that you are familiar with and that has some risks. Describe some of the risks and some safety practices. Generate analogies between your activity and risks related to computer systems. Use terms learned in class such as boundaries of acceptable risk, IV&V, redundancy, safety critical, HRO, etc.
3. There is an urban legend that a major retail company “lost” a warehouse from its inventory system for three years. The warehouse received no goods and shipped none. A separate system handled payroll, so the employees continued to get paychecks. To what extent is this a computer failure? What other important factors are part of the problem?
4. Watch the videos on the day 21 slides that we didn’t have time to watch in class. Pay attention to how different people reacted to the same situation in each case. Name at least one previous (before today) class term and how it applies to any of the cases studied in class.

Uberlingen Crash is the video but it doesn’t open so you can type on the google and it will show the video. That is the video about question 4
Solution PreviewI would assign the manufacturer a responsibility of 25%, the computer programmer 50% and the hospital or the clinics 15%. This perception is based on the fact that despite that the manufacturer developed equipment with radiation emission…
