availability | refers to the time frames when the system is operational |
unavailable | when a system is not operating and cannot be used |
high availability | occurs when a system is continuously operational at all times |
maintainability / flexibility | refers to how quickly a system can transform to support environmental changes |
portability | refers to the ability of an application to operate on different devices or software platforms, such as different operating systems |
reliability / accuracy | ensures all systems are functioning correctly and providing accurate information |
vulnerability | a system weakness that can be exploited by a threat |
scalability | refers to how well a system can adapt to increased demands |
performance | measures how quickly a system performs a certain process or transaction |
capacity | represents the maximum throughput a system can deliver |
capacity planning | determine the future IT infrastructure requirement for new equipment and additional network capacity |
usability | the degree to which a system is easy to learn, efficient, and satisfying to use |
serviceability | how quickly a third party or vendor can change a system to ensure it meets user needs and the terms of any contracts, including agreed levels of reliability, maintainability, or availability |
Moore's Law | refers to the computer chip performance per dollar doubles every 18 months |
sustainable, or "green", MIS | describes the manufacture, management, use, and disposal of information technology in a way that minimizes damage to the environment, which is a critical part of a corporation's responsibility |
corporate social responsibility | companies' acknowledged responsibility to society |
increased electronic waste, increase energy consumption, increase carbon emissions | Pressures Driving Sustainable MIS Infrastructures |
ewaste | old computer equipment, does not end up in a landfill, where the toxic substances it contains can leach into groundwater, among other problems |
sustainable MIS disposal | refers to the safe disposal of IT assets at the end of their life cycle |
