Global E-Business: How Businesses Use Information Systems Chapter 6 (10E)

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

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

Examples of How IT Changes Business Processes Renting a movie (transform) Downloading a music track (brand new) Ordering a book (brand new) Returning a rental car (transform) Tracking a package (brand new) Trading stocks (transform) Paying bills (transform) Developing a photograph (transform) Designing an airplane/car (transform) Registering for a class (transform) Capturing and sharing employee knowledge (new)

Cross-Functional Business Processes: Transcend boundary between sales, marketing, manufacturing, and research and development Group employees from different functional specialties to a complete piece of work Example: Order Fulfillment Process Integrating Functions and Business Processes:

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

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

Transaction Processing Systems (TPS) Management Information Systems (MIS) Decision Support Systems (DSS) Executive Support Systems (ESS) MAJOR TYPES OF SYSTEMS IN ORGANIZATIONS

Ways to Organize Information Systems By the groups they serve Operational level Management level Strategic level By functional area Sales and marketing Manufacturing and production Finance and accounting Human resources

The Four Major Types of Information Systems by the Groups They Serve and Functional Area

Transaction Processing Systems (TPS) Basic business systems that serve the operational level A computerized system that facilitates daily routine transactions necessary to the conduct of the business and captures and stores data associated with the transaction

Typical Applications of TPS

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

Management Information Systems (MIS) (continued)

Management Information Systems (MIS) (continued) A sample MIS report

Structured and semi-structured decisions Report control oriented Past and present data Internal orientation Lengthy design process Characteristics of Management Information System (MIS)

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

Decision-Support Systems (DSS) (Continued) Voyage-estimating decision-support system

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

Top level management Designed to the individual Ties CEO to all levels Very expensive to keep up Extensive support staff Executive Support System (ESS)

Model of a Typical Executive Support System

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.

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)

Systems for Enterprise-Wide Process Integration Enterprise applications: Designed to support organization-wide process coordination and integration Examples of such systems Supply chain management systems (SCM) Customer relationship management systems (CRM) Knowledge management systems
