1. INFORMATION SYSTEMS IN THE ENTERPRISE Chapter 2 (9E)

2. What Are Information Systems? An information system (IS) is a set of interrelated components working together to (1) facilitate operational functions and (2) support management decision making by producing information that enables managers to plan and control. –Components include hardware, software, data, people, and procedures An (IS) is an organizational and management solution based on information technology to a challenge posed by the environment Information technology (IT) includes computer hardware, software, storage technologies, and telecommunications/networks

3. Basic Functions of Information Systems Information systems are models of physical systems Information systems engage in four basic activities in order to support operations and management decision making –Input –Processing –Output Feedback for operations and decision making Feedback on the performance of IS –Storage

10. Management Information System (MIS) MIS serve the management level of the organization, providing managers with reports and online access to the organization’s current performance and historical records. Inputs: High-volume data Processing: Simple models Outputs: Summary reports Users: Middle managers Example: Annual budgeting

14. Decision Support System (DSS) DSS serve the management level and help managers make decision that are unique, rapidly changing, and not easily specified in advance (use of mathematical models) Inputs: Low-volume data Processing: Interactive (e.g., what-if analysis), data-mining, OLAP Outputs: Decision analysis Users: Professionals, staff Example: Contract cost analysis

16. Executive Support System (ESS) ESS support strategic level managers to help make decisions that are non-routine requiring judgment, evaluation, and insight. Inputs: Aggregate data Processing: Interactive Outputs: Projections Users: Senior managers Example: 5-year operating plan

19. Interrelationships Among Systems TPS are typically a major source of data for other systems MIS are sources for DSS and ESS DSS is a source for ESS Sometimes a single system serves many purposes In contemporary digital firms, the different types of systems are closely linked to one another. This is the ideal. In traditional firms these systems tend to be isolated from one another, and information does not flow seamlessly from one end of the organization to the other. Efficiency and business value tend to suffer greatly in these traditional firms.

32. Organizational Challenges E-commerce, e-business, and global competition force companies to bring products to market faster, improve customer service, and execute processes more efficiently. These objectives require integrated information from different functional areas, levels of management, and coordination with business partners (e.g., customers and suppliers). Solution –Enterprise applications that coordinate, activities, and knowledge across intra- and inter- firm boundaries –Interorganizational systems that automate information flows across organizational boundaries (an inter-firm system)

33. Business Processes Environmental factors and enterprise applications have forced businesses to examine their processes. –Manner in which work is organized, coordinated, and focused to produce a valuable product or service –Concrete work flows of material, information, and knowledge—sets of activities Information systems help organizations –Achieve great efficiencies by automating parts of processes –Rethink and streamline processes

34. Manufacturing and production: Assembling product, checking quality, producing bills of materials Sales and marketing: Identifying customers, creating customer awareness, selling Finance and accounting: Paying creditors, creating financial statements, managing cash accounts Human Resources: Hiring employees, evaluating performance, enrolling employees in benefits plans Examples of Business Processes
