2 4-2 LEARNING OUTCOMES 1. Explain MIS infrastructure and its three primary types 2. Identify the three primary areas associated with an information MIS infrastructure 3. Describe the characteristics of an agile MIS infrastructure

3 4-3 THE BUSINESS BENEFITS OF A SOLID MIS INFRASTRUCTURE O MIS infrastructure – Includes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets O Hardware O Software O Network O Client O Server

4 4-4 THE BUSINESS BENEFITS OF A SOLID MIS INFRASTRUCTURE O Supporting operations O Information MIS infrastructure O Supporting change O Agile MIS Infrastructure O Supporting the environment O Sustainable MIS infrastructure

5 4-5 SUPPORTING OPERATIONS: INFORMATION MIS INFRASTRUCTURE O Backup and recovery plan O Disaster recovery plan O Business continuity plan

6 4-6 Backup and Recovery Plan O Backup – An exact copy of a system’s information O Recovery – The ability to get a system up and running in the event of a system crash or failure O Fault tolerance O Failover O Failback

7 4-7 Backup and Recovery Plan O 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 O 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 4-8 Backup and Recovery Plan

9 4-9 Backup and Recovery Plan O Hot site - A separate and fully equipped facility where the company can move immediately after a disaster and resume business O Cold site - A separate facility that does not have any computer equipment, but is a place where employees can move after a disaster O Warm site – A separate facility with computer equipment that requires installation and configuration

10 4-10 Business Continuity Plan O 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 4-11 Business Continuity Plan O Emergency – a sudden unexpected event requiring immediate action O Emergency preparedness – ensures a company is ready to respond to an emergency in an organized, timely, and effective manner

12 4-12 Business Continuity Plan

13 4-13 Business Continuity Plan O Business impact analysis – Identifies all critical business functions and the effect that a specific disaster may have upon them O Technology failure – occurs when the ability of a company to operate is impaired because of a hardware, software, or data outage O Incident – Unplanned interruption of a service O Incident management – the process responsible for managing how incidents are identified and corrected

14 4-14 SUPPORTING CHANGE: AGILE MIS INFRASTRUCTURE O Characteristics of an agile MIS infrastructure O Accessibility O Availability O Maintainability O Portability O Reliability O Scalability O Usability

15 4-15 Accessibility O Accessibility - Refers to the varying levels that define what a user can access, view, or perform when operating a system O Web accessibility – Allows people with disabilities to use the Web O Administrator access – Unrestricted access to the entire system

16 4-16 Availability O Availability – Time frames when the system is operational O Unavailable – Time frames when a system is not operating and cannot be used O High availability – System is continuously operational at all times

17 4-17 Maintainability O Maintainability – How quickly a system can transform to support environmental changes O Organizations must watch today’s business, as well as tomorrow’s, when designing and building systems O Systems must be flexible enough to meet all types of business changes

18 4-18 Portability O Portability – The ability of an application to operate on different devices or software platforms

19 4-19 Reliability O Reliability - Ensures a system is functioning correctly and providing accurate information O Reliability is another term for accuracy when discussing the correctness of systems within the context of efficiency IT metrics O Vulnerability – a system weakness that can be exploited by a threat

20 4-20 Scalability O Scalability - How well a system can scale up, or adapt to the increased demands of growth O Performance - Measures how quickly a system performs a process or transaction O Capacity planning - Determines future environmental infrastructure requirements to ensure high-quality system performance

21 4-21 Usability O Usability – The degree to which a system is easy to learn and efficient and satisfying to use O 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
