| business continuity planning (BCP) | a plan for how an organization will recover and restore partially or completely interrupted critical function(s) within a predetermined time after a disaster or extended disruption |
| Disaster Recovery Plan, Business Impact Analysis, Emergency Notification Services, Technology Recovery Strategies | Business Continuity Planning Focus Areas |
| business impact analysis | a process that identifies all critical business functions and the effect that a specific disaster may have upon them |

| incidents | unplanned interruption of a service |
| incident record | contains all of the details of an incident |
| incident management | the process responsible for managing how incidents are identified and corrected |
| technology recovery strategies | focus specifically on prioritizing the order for restoring hardware, software, and data across the organization that best meets business recovery requirements |
| Accessibility, Availability, Maintainability, Portability, Reliability, Scalability, Usability | Agile MIS Infrastructures Characteristics |
| accessibility | refers to the varying levels that define what a user can access, view, or perform when operating a system |
| administrator access | unrestricted access to the entire system |
| web accessibility | people with disabilities, including visual, auditory, physical, speech, cognitive, and neurological disabilities, can use the web |
| web accessibility initiative (WAI) | brings together people from industry, disability organizations, government, and research labs from around the world to develop guidelines and resources to help make the web accessible to people with disabilities |
| 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 |
| energy consumption | the amount of energy consumed by business processes and systems |
| carbon emissions | includes the carbon dioxide and carbon monoxide in the atmosphere, produced by business processes and systems |
| Grid Computing, Virtualized Computing, Cloud Computing | Sustainable MIS Infrastructure Components |
