The Strategic Role Of Information Systems
Introduction Information system (IS) äSet of interrelated components: collect, manipulate, store, and disseminate data and information äProvides feedback to meet an objective äExamples: ATMs, airline reservation systems, course reservation systems
Information Concepts: Data, Information, and Knowledge Data: raw facts äAlphanumeric, image, audio, and video Information: collection of facts organized in such a way that they have additional value beyond the value of the facts themselves

The Value of Information Value of information is directly linked to how it helps decision makers achieve their organization’s goals For example, value of information might be measured in: äTime required to make a decision äIncreased profits to the company

Types of Information Systems
TYPES OF INFORMATION SYSTEMS
Enterprise Systems
Benefits: Firm structure and organization: One organization Management: Firm-wide knowledge-based management processes Technology: Unified platform Business: More efficient operations and customer-driven business processes Challenges: Difficult to build: Require fundamental changes in the way the business operates Technology: Require complex pieces of software and large investments of time, money, and expertise Centralized organizational coordination and decision making: Not the best way for the firms to operate
Management Information Systems Management information system (MIS) äOrganized collection of people, procedures, software, databases, and devices äProvides routine information to managers/decision makers Primary focus is operational efficiency
Management Information Systems Figure 1.10: Management Information System
Decision Support Systems Decision support system (DSS) äOrganized collection of people, procedures, software, databases, and devices äSupports problem-specific decision making Focus is on decision-making effectiveness
Decision Support Systems Figure 1.11: Essential DSS Elements
Specialized Business Information Systems: Knowledge Management, Artificial Intelligence, Expert Systems, and Virtual Reality Knowledge management systems (KMSs): an organized collection of people, procedures, software, databases, and devices to create, store, share, and use the organization’s knowledge and experience Artificial intelligence (AI): field in which the computer system takes on the characteristics of human intelligence
