  9. Transformation of economies • Industrial economies are being transformed to knowledge & information-based service economies • Manufacturing has been moving to low-wage countries • In the new economies, knowledge & information are key ingredients in creating wealth

  10. Knowledge & information • Knowledge & information revolution began at the turn of the 20th century and has gradually accelerated • Knowledge & information work now accounts for about 60% of the US gross national product and about 55% of the labor force • Knowledge & information are the foundations for many new services and products

  11. Knowledge & production • Knowledge & information intense products require great deal of learning and knowledge to produce • Knowledge utilization in production of traditional products has increased significantly

  12. Knowledge & IS • In knowledge & information-based economy, IT and systems take on great importance • Across all industries information and the enabling technologies have become critical strategic assets for business firms and their managers • Information systems are needed to optimize the flow of information and knowledge within the organization • Information systems also helps management maximize the firm’s knowledge resources

  13. Benefits of disintermediation The typical distribution channel has several intermediary layers, each of which adds to the final cost of a product, such as a sweater. Removing layers lowers the final cost to the consumer.

  14. Transformation of enterprise • Transformation of organizing and managing • Traditional business forms have been replaced • New business forms have developed • Traditional management has been transformed

  15. Traditional business forms • Hierarchical & centralized • Structured arrangement of specialists • Reliance on standard operating procedures • Delivering mass-produced products and services • Targeting general mass markets

  19. New management & IS • Information technology makes this style of management possible • Information technology makes the firm more dependent on knowledge, learning and decision-making of individual employees

  20. Outcomes of enterprise transformation • Flattening of the firm • Decentralization • Flexibility of workers • Location independence • Low transaction and coordination costs • Empowerment of the worker • Collaborative work and teamwork

  21. Transformation of business • How information systems are transforming business • Increase in wireless technology use, Web sites • Shifts in media and advertising • New federal security and accounting laws • Globalization opportunities • Internet has drastically reduced costs of operating on global scale • Presents both challenges and opportunities

  22. Capital Investment in IT Information technology investment, defined as hardware, software, and communications equipment, grew from 32% to 51% between 1980 and 2008.Source: Based on data in U.S. Department of Commerce, Bureau of Economic Analysis, National Income and Product Accounts, 2008.

  23. Digital firms • In the emerging, fully digital firm • Significant business relationships are digitally enabled and mediated • Core business processes are accomplished through digital networks • Key corporate assets are managed digitally • Digital firms offer greater flexibility in organization and management • Time shifting, space shifting

  24. Virtual Meetings: Smart Management • What are the advantages of using videoconferencing technologies? What are the disadvantages? • What is telepresence and what sorts of companies are best suited to use it as a communications tool? • What kinds of companies could benefit from using videoconferencing? Are there any companies that might not derive any benefits from this technology?

  25. Corporate goals • Growing interdependence between ability to use information technology and ability to implement corporate strategies and achieve corporate goals • Business firms invest heavily in information systems to achieve six strategic business objectives: • Operational excellence • New products, services, and business models • Customer and supplier intimacy • Improved decision making • Competitive advantage • Survival

  26. Operational excellence • Improvement of efficiency to attain higher profitability • Information systems, technology an important tool in achieving greater efficiency and productivity • Example: Wal-Mart’s RetailLink system links suppliers to stores for superior replenishment system

  27. Business model • Business model: describes how company produces, delivers, and sells product or service to create wealth • Information systems and technology: major enabling tool for new products, services, business models • Examples: Apple’s iPod, iTunes, and iPhone, Netflix’s Internet-based DVD rentals

  28. Customer & supplier intimacy • Serving customers well leads to customers returning, which raises revenues and profits • Example: High-end hotels that use computers to track customer preferences and use to monitor and customize environment • Intimacy with suppliers allows them to provide vital inputs, which lowers costs • Example: J.C.Penney’s information system which links sales records to contract manufacturer

  29. Improved decision making • Without accurate information: • Managers must use forecasts, best guesses, luck • Leads to: • Overproduction, underproduction of goods and services • Misallocation of resources • Poor response times • Poor outcomes raise costs, lose customers • Example: Verizon’s Web-based digital dashboard to provide managers with real-time data on customer complaints, network performance, line outages, etc.

  30. Competitive advantage • Delivering better performance • Charging less for superior products • Responding to customers and suppliers in real time • Example: Toyota and TPS (Toyota Production System) enjoy a considerable advantage over competitors – information systems are critical to the implementation of TPS

  31. Survival • Information technologies as a necessity for business • May be: • Industry-level changes, e.g. Citibank’s introduction of ATMs • Governmental regulations requiring record-keeping • Examples: Toxic Substances Control Act, Sarbanes-Oxley Act

  32. Organizations & IT In contemporary systems there is a growing interdependence between a firm’s information systems and its business capabilities. Changes in strategy, rules, and business processes increasingly require changes in hardware, software, databases, and telecommunications. Often, what the organization would like to do depends on what its systems will permit it to do.

  33. IS definitions • Information system: • Set of interrelated components • Collect, process, store, and distribute information • Support decision making, coordination, and control • Information vs. data • Data are streams of raw facts • Information is data shaped into meaningful form

  34. Data and Information Raw data from a supermarket checkout counter can be processed and organized to produce meaningful information, such as the total unit sales of dish detergent or the total sales revenue from dish detergent for a specific store or sales territory.

  35. IS activities • Three activities produce information organizations need: • Input: Captures raw data from organization or external environment • Processing: Converts raw data into meaningful form • Output: Transfers processed information to people or activities that use it

  36. Feedback loop • Feedback – output that is returned to the appropriate members of the organization to help them • Evaluate the output • Correct the input • Computers and software are technical foundation and tools, similar to the material and tools used to build a house

  37. Information systems & IT • Computers and related software programs are the technical foundations, i.e. tools and materials of modern information systems • Understanding information systems requires understanding: • Problems they are designed to solve, • Their architectural and design elements • The organizational process that lead to these solutions

  38. Computers & IS Using information systems effectively requires an understanding of the organization, management, and information technology shaping the systems. An information system creates value for the firm as an organizational and management solution to challenges posed by the environment.

  39. Organizational dimension • Hierarchy of authority, responsibility • Senior management • Middle management • Operational management • Knowledge workers • Data workers • Production or service workers

  40. Levels in a Firm Business organizations are hierarchies consisting of three principal levels: senior management, middle management, and operational management. Information systems serve each of these levels. Scientists and knowledge workers often work with middle management.

  41. Business functions • Separation of business functions • Sales and marketing • Human resources • Finance and accounting • Manufacturing and production • Unique business processes • Unique business culture • Organizational politics

  42. Management dimension • Managers set organizational strategy for responding to business challenges • In addition, managers must act creatively: • Creation of new products and services • Occasionally re-creating the organization

  43. Technology dimension • Computer hardware and software • Data management technology • Networking and telecommunications technology • Networks, the Internet, intranets and extranets, World Wide Web • IT infrastructure: provides platform that system is built on

  44. Example: UPS • Read the UPS Case and then discuss the following questions: • What are the inputs, processing, and outputs of UPS’s package tracking system? • What technologies are used by UPS? • How are these technologies related to UPS’s business strategy? • What problems do UPS’s information systems solve? • What would happen if these systems were not available?

  45. UPS tracking system • Dimensions of UPS tracking system • Organizational: • Procedures for tracking packages and managing inventory and provide information • Management: • Monitor service levels and costs • Technology: • Handheld computers, bar-code scanners, networks, desktop computers, etc.

  46. Business perspective • Information system is instrument for creating value • Investments in information technology will result in superior returns: • Productivity increases • Revenue increases • Superior long-term strategic positioning

  47. Business information • Business information value chain • Raw data acquired and transformed through stages that add value to that information • Value of information system determined in part by extent to which it leads to better decisions, greater efficiency, and higher profits • Business perspective: Calls attention to organizational and managerial nature of information systems

  48. Information value chain From a business perspective, information systems are part of a series of value-adding activities for acquiring, transforming, and distributing information that managers can use to improve decision making, enhance organizational performance, and, ultimately, increase firm profitability.

  49. Returns from IT investments • Investing in information technology does not guarantee good returns • Considerable variation in the returns firms receive from systems investments • Factors: • Adopting the right business model • Investing in complementary assets (organizational and management capital)

  50. Complementary assets • Assets required to derive value from a primary investment • Firms supporting technology investments with investment in complementary assets receive superior returns • E.g.: invest in technology and the people to make it work properly
