4 Welcome to the Information Age The Evolution of the Information Age: Typical Example, USA
Agricultural Age: The period up to the 1800s, when the majority of workers were farmers whose lives revolved around agriculture. Industrial Age: The period from the 1800s to 1957, when work processes were simplified through mechanization and automation. © Adapted from Pearson Prentice Hall

5 Welcome to the Information Age The Evolution of the Information Age : Typical Example, USA (Continued) Information Age: The period that began in 1957, in which the majority of workers are involved in the creation, distribution, and application of information. Knowledge Workers: Workers involved in the creation, distribution, and application of information. © Adapted from Pearson Prentice Hall

7 WHY? What has caused this? An information-based society has arisen.
Welcome to the Information Age The Characteristics of the Information Age (Continued) An information-based society has arisen. Information Society: A society in which more people work at handling information than at agriculture and manufacturing combined. Businesses depend on information technology to get their work done. WHY? What has caused this? © Adapted from Pearson Prentice Hall

8 Welcome to the Information Age The Characteristics of the Information Age (Continued)
What happened? Information and knowledge became assets. Those assets require: Generation/development Management (how to distribute, assign quality/quantity …etc) Storage Sell/buy © Adapted from Pearson Prentice Hall

9 Work processes are being transformed to increase productivity.
Welcome to the Information Age The Characteristics of the Information Age (Continued) Work processes are being transformed to increase productivity. Work Processes: The combination of activities that workers perform, the way they perform those activities, and the tools they use. Productivity: The relationship between the results of an activity (output) and the resources used to create those results (inputs). Effectiveness: The extent to which desirable results are achieved. © Adapted from Pearson Prentice Hall

11 Welcome to the Information Age The Characteristics of the Information Age (Continued)
Information technology provides the means to rethink/recreate/reengineer conventional business processes. Reengineering: The reshaping of business processes to remove barriers that prohibit an organization from providing better products and services and to help the organization capitalize on its strengths. Business Processes: Collections of activities, often spanning several departments, that take one or more kinds of input and create a result that is of value to a company’s customers. © Adapted from Pearson Prentice Hall
