Hardware
Software
Network
Client
Server

5. SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE
Backup and recovery plan
Disaster recovery plan
Business continuity plan

6. Backup and Recovery Plan
Backup – An exact copy of a system’s information
Recovery – The ability to get a system up and running in the event of a system crash or failure
Fault tolerance
Failover
Failback

7. Backup and Recovery Plan
Disaster recovery plan - A detailed process for recovering information or an IT system in the event of a catastrophic disaster such as a fire or flood
Disaster recovery cost curve - Charts (1) the cost to the organization of the unavailability of information and technology and (2) the cost to the organization of recovering from a disaster over time

8. Backup and Recovery Plan

9. Backup and Recovery Plan
Hot site - A separate and fully equipped facility where the company can move immediately after a disaster and resume business
Cold site - A separate facility that does not have any computer equipment, but is a place where employees can move after a disaster
Warm site – A separate facility with computer equipment that requires installation and configuration

10. Business Continuity Plan
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

11. Business Continuity Plan
Emergency – a sudden unexpected event requiring immediate action
Emergency preparedness – ensures a company is ready to respond to an emergency in an organized, timely, and effective manner

12. Business Continuity Plan

13. Business Continuity Plan
Business impact analysis – Identifies all critical business functions and the effect that a specific disaster may have upon them
Technology failure – occurs when the ability of a company to operate is impaired because of a hardware, software, or data outage
Incident – Unplanned interruption of a service
Incident management – the process responsible for managing how incidents are identified and corrected

14. SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE
Characteristics of an agile MIS infrastructure
Accessibility
Availability
Maintainability
Portability
Reliability
Scalability
Usability

15. Accessibility
Accessibility - Refers to the varying levels that define what a user can access, view, or perform when operating a system
Web accessibility – Allows people with disabilities to use the Web
Administrator access – Unrestricted access to the entire system

16. Availability Availability – Time frames when the system is operational
Unavailable – Time frames when a system is not operating and cannot be used
High availability – System is continuously operational at all times

17. Maintainability
Maintainability – How quickly a system can transform to support environmental changes
Organizations must watch today’s business, as well as tomorrow’s, when designing and building systems
Systems must be flexible enough to meet all types of business changes

18. Portability
Portability – The ability of an application to operate on different devices or software platforms

19. Reliability
Reliability - Ensures a system is functioning correctly and providing accurate information
Reliability is another term for accuracy when discussing the correctness of systems within the context of efficiency IT metrics
Vulnerability – a system weakness that can be exploited by a threat

20. Scalability
Scalability - How well a system can scale up, or adapt to the increased demands of growth
Performance - Measures how quickly a system performs a process or transaction
Capacity planning - Determines future environmental infrastructure requirements to ensure high-quality system performance

21. Usability
Usability – The degree to which a system is easy to learn and efficient and satisfying to use
Serviceability – How quickly a third-party can change a system to ensure it meets user needs and the terms of any contracts, including agreed levels of reliability, maintainability, or availability
