An office automation system is an information system that supports the wide range of business office activities that provide for improved work flow between workers.

24 Role of Information Systems Enabling Processes and Functions in Organizations Supporting Processes and Functions in Organizations The websites of these companies enable the sale of products. These companies primarily do not have any shops/showrooms for consumers or may fail to operate efficiently without their websites. The websites of these companies support the sale of electronic products which are primarily done in the shops

25 Electronic Commerce: Sharing business information, managing business relationships and facilitating transactions with Internet technology. (linking buyers and sellers). Electronic Business: Executing all the firm s business processes with Internet technology. (sales, finance, human resources, manufacturing) Intranet: Business builds private, secure network based on Internet technology Extranet: Extension of intranet to authorized external users

26 Transformation of the Business Enterprise Flattening Decentralization Flexibility Location independence Low transaction and coordination costs Empowerment Collaborative work and teamwork

27 Business Perspective of Information Systems People Structure Procedures Politics Culture ORGANIZATION TECHNOLOGY INFORMATION SYSTEMS MANAGEMENT Hardware Software Storage Senior, middle, operational

28 Key Elements: Organizations People: Managers, knowledge workers, data workers, production or service workers Structure: Organization chart, groups of specialists, products, geography

29 Organizations Operating procedures: Standard operating procedures (SOP, rules for action) Politics: Power to persuade, get things done Culture: Customs of behavior

30 Levels: Management Senior managers: make long-range strategic decisions about products and services Middle managers: Carry out the programs and plans of senior management Operational managers: monitor the firm s daily activities

31 Computer Technology Tools managers use to cope with change Hardware: Physical equipment Software: Detailed preprogrammed instructions Storage: Physical media for storing data and the software

32 So what is the DIGITAL FIRM?
