Complete information contains all of the important facts. Relevant information is important to the decision maker. Timely information is available when needed. Verifiable information can be checked to make sure it is correct. Accessible information can be obtained by the users who need it. Secure information is safe from unauthorized users. 8 4

5 thus... Usefulness of information depends on quality and accessibility BUT. Usefulness also depends on purpose and context Information comes in different forms - not all of which can be quantified: hard vs. soft data Ownership is difficult to maintain More is not always better 9 Definitions The business environment includes the firm itself and everything else that affects its success, such as competitors; suppliers; customers; regulatory agencies; and demographic, social, and economic conditions. A firm (or government organization) consists of a large number of interdependent business processes that work together to generate products or services in a business environment. A business process is a related group of steps or activities that use people, information, and other resources to create value for internal or external customers of a firm. 10 5

6 What is an Information System? An information system is the set of interrelated components that collect, process, store and distribute information used by/support one or more business process. Input: The collection of raw data. Processing: The manipulation of data into information. Output: Distributing valuable information. Includes both technology and people Information technology is the hardware, telecommunications and software that make information systems possible. 11 Functions of Information Systems Environment Organization Information System INPUT Processing Classify Arrange Calculate OUTPUT Feedback 12 6

8 Definitions Feedback Output that is returned to the appropriate members of the organization to help them evaluate or correct input. Computer-based information systems (CBIS) Information systems that rely on computer hardware and software for processing and disseminating information. Formal system System resting on accepted and fixed definitions of data and procedures, operating with predefined rules. 15 Examples of Information Systems 16 8

9 Definitions: Organization Standard operating procedures (SOPs) Formal rules for accomplishing tasks that have been developed to cope with expected situations. Knowledge workers People such as engineers or architects who design products or services and create knowledge for the organization. Data workers People such as secretaries or bookkeepers who process the organization's paperwork. Production or service workers People who actually produce the products or services of the organization. 17 Definitions: Management Senior managers People occupying the topmost hierarchy in an organization who are responsible for making long-range decisions.

11 Brief History of IS 1950's : Electronic Data Processing/ Automatic Data Processing 1960's : Management Information Systems (i.e. Report generating systems) 1970's : Decision Support Systems (DSS), Office Automation Systems 1980's : Information as strategic tool, End-User Computing, Managerial control 1990's : Integration: Core activities + Information as a product 21 The New Role of Information Systems in Organizations Widening scope of information systems Data processing -> management control -> decision support-> information as a resource Network revolution Networked enterprise Flattening organizations Separating work from location Reorganizing workflow Increasing flexibility of organization Mass customization: Products can be easily customized with no added cost for small production runs.
