The purpose of a reactor protection system (RPS) is to protect the integrity of the plant’s nuclear fuel by monitoring inputs from the reactor core. To accomplish this monitoring, application software must check sensors located throughout the reactor. If any safe operating values are exceeded, the software takes action, such as injecting cooling water or shutting the reactor down by inserting control rods. 2. Advantages of proprietary software: You can get exactlywhat you need in termsof features, reports, andso on. Being involved in thedevelopment offerscontrol over the results. You can modify featuresthat you might need tocounteract an initiativeby competitors or tomeet new supplier orcustomer demands. Disadvantages of proprietary software It can take a long time and significant resources to develop required features. In-house system development staff may be hard pressed to provide the required level of ongoing support and maintenance because of pressure to move on to other new projects. The features and performance of software that has yet to be developed presents more potential risk. Advantages of off-the-shelf software The initial cost is lowerbecause the softwarefirm can spread thedevelopment costs overmany customers.

Fundamentals of Information Systems, 8 th Edition The software is likely tomeet the basic businessneeds—you can analyzeexisting features and theperformance of thepackage beforepurchasing. The package is likely tobe of high quality becausemany customerfirms have tested thesoftware and helpedidentify its bugs. Disadvantages of off-the-shelf software An organization might have topay for features that are notrequired and never used. The software might lackimportant features, thusrequiring future modificationor customization. This lackcan be very expensive becauseusers must adopt future releasesof the software as well. The software might not matchcurrent work processes anddata standards. Critical Thinking Questions 1. Using software to control power plants offers the potential of increased safety compared to earlier methods. 2. Student responses will vary. Some may suggest that programmers who write software for these system be required to pass standardized official examinations. Information Systems @ Work Printing Livers at Organovo Discussion Questions 1. To create human tissues and organs, scientists must build highly customized artificial scaffolds to seed the cells temporarily until they are strong enough to stand alone. 3D printing can help because unlike other manufacturing devices, 3D printers have a unique ability to customize a product by tweaking the blueprint that is fed into the printer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
