Flexibility Can the new system perform diverse operations that were not possible before? Reliability Are there fewer breakdowns of this system compared with the previous one? Is uptime very high with this system? The reliability/uptime of an on-line network is probably the number one criterion by which to judge its design and development. Acceptance Evaluate whether both the information providers and the information users have accepted the system. Controls Are adequate security and control mechanisms in place in order to prevent threats to the system such as errors and omissions, fraud and defalcation, lost data, breaches of privacy, disastrous events, and the like? Documentation Does the system have adequate written/pictorial descriptions documenting all of its hardware, protocols, software, circuits, and user manuals? Training Are training courses adequate and are they offered on a continuous basis, especially for terminal operators? Are training manuals adequate and updated on a regular basis? System Life Is the life of the system adequate? When two to five years are spent designing and implementing a system, the system life should be of adequate duration to take advantage of the economies of scale.

    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.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
