BUILDING SUSTAINABLE MIS INFRASTRUCTURES BU6010: Management Information System Module 3 – Part 2  Learning Outcomes Explain MIS infrastructure and its three primary types Identify the three primary areas associated with an information MIS infrastructure Describe the characteristics of an agile MIS infrastructure BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 2 The business benefits of a solid MIS infrastructure MIS infrastructure – Includes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets Hardware Software Network Client Server BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 3 The Business Benefits of a Solid MIS Infrastructure Information MIS Infrastructure: Supports Operations Agile MIS Infrastructure: Supports Change Sustainable MIS infrastructure: Supports the Environment BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 4 Supporting Operations: Information MIS Infrastructure Backup and recovery plan Disaster recovery plan Business continuity plan BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 5 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: A general concept that a system has the ability to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service. Failover: A specific type of fault tolerance, occurs when a redundant storage server offers an exact replica of the real-time data and if the primary server crashes the users are automatically directed to the secondary server or backup server. Failback: Occurs when the primary machine recovers and resumes operations taking over from the secondary server. 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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 6 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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 7 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 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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 8  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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 9 Supporting Change: Agile MIS Infrastructure Characteristics of an agile MIS infrastructure Accessibility Availability Maintainability Portability Reliability Scalability Usability BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide 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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide Maintainability Maintainability – How quickly a system can transform to support environmental changes Organizations must watch today’s business, as well as tomorrows, when designing and building systems Systems must be flexible enough to meet all types of business changes BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide Portability Portability – The ability of an application to operate on different devices or software platforms Most applications want to operate on as many devices as possible BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide  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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide  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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide  Usability Usability – The degree to which a system is easy to learn and efficient and satisfying to use Providing hints, tips, shortcuts, and instructions for any system, regardless of its ease of use, is recommended. 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 BU6010: Management Information System - First 2024/2025Module 3: Building Sustainable MIS Slide
