Description
Experience Level: Entry
Question 1
Discuss the tasks of SQA trustees.
Discuss the audit types the SQA unit is involved with.
Describe the typical tasks of the head of an SQA unit.
Question 2
Case Study
The Therac-25 machine is a case of an industrial support system that had lethal consequences due to errors in software. The Therac-25 was a radiation machine used in hospitals to perform radiation therapy and create X-ray pictures of patients. It was involved in a series of accidents that caused deaths and severe injuries to people who were exposed to the machine. The following description of the problem was taken from Reference 1:
The machine offered two modes of radiation therapy:
• Direct electron-beam therapy, which delivered low doses of high-energy (5 MeV to 25 MeV) electrons over short periods of time
• Megavolt X-ray therapy, which delivered X-rays produced by colliding high-energy (25 MeV) electrons into a “target”
When operating in direct electron-beam therapy mode, a low-powered electron beam was emitted directly from the machine then spread to safe concentration using scanning magnets. When operating in megavolt X-ray mode, the machine was designed to rotate four components into the path of the electron beam: a target, which converted the electron beam into X-rays; a flattening filter, which spread the beam out over a larger area; a set of movable blocks (also called a collimator), which shaped the X-ray beam; and an X-ray ion chamber, which measured the strength of the beam.
The accidents occurred when the high-power electron beam was activated instead of the intended low power beam, and without the beam spreader plate rotated into place. The machine’s software did not detect that this had occurred, and therefore did not prevent the patient from receiving a potentially lethal dose of radiation. The high-powered electron beam struck the patients with approximately 100 times the intended dose of radiation, causing a feeling described by patient Ray Cox as “an intense electric shock.” It caused him to scream and run out of the treatment room. Several days later, radiation burns appeared and the patients showed the symptoms of radiation poisoning. In three cases, the injured patients died later from radiation poisoning.
(i) Suggest in which category of IT system the above case study is dealing with?
(ii) Provide two quality characteristics associated with the IT system’s category, as identified in (i)?
(iii) From the case study, which main quality characteristic has been missed and describes the impact/cost of missing this quality
