Read Medical Devices: The Therac-25 by Leveson (which is an updated version of An Investigation of the Therac-25 Accidents by Leveson and Turner). Although there are many cases in which software design and failure has led to the loss of life, the case of the Therac-25 is among the best known and most widely cited because of the depth of analysis that was performed by professor Nancy Leveson and her graduate student Clark Turner.
The Leveson paper is quite long, and not all parts are equally important:
As you read, think about the following:
Before you come to this recitation, write up (on paper) a brief answer to the following (really—we don't need more than a sentence or so for each question):
(There are multiple possible answers to each of these questions.)
This assignment is a good opportunity for you to begin practicing how to get the interesting stuff out of a paper without getting bogged down in minor detail:
As you read the paper, try to distinguish solid technical facts from higher-level statements that the authors are trying to make about process, procedures and policy. You might find it useful to note the places where you agree or disagree with the authors' analysis.
Finally, don't be dismayed by unfamiliar technical jargon; make a guess about what it means and move on. The authors may explain it two paragraphs later, or two pages later, or perhaps never get around to it. There is a good chance that you will discover that it didn't actually matter. But if it does, you have something to ask about in recitation.
