The Network Economy
8. The New Economy A controversial issue
The importance of knowledge
High tech often replaces human communication and brainpower
Electronic transactions
9. The Network Economy The advent was foreseen in 1969 by Peter Drucker
Teacher, writer, consultant, thinker, and lecturer on the contemporary organization
Wall Street Journal editor and frequent HBR contributor
10. The Network Economy Connected World
Increasing Web traffic
Novice users acquire computes
New web participants
Web bots, intelligent agents, mobile objects, etc.
Moores Law
Gilders Law
Metcalfe's Law
11. The Network Economy The observation made in 1965 by Gordon Moore, co-founder of Intel.
The number of transistors per square inch on integrated circuits had doubled every year since the integrated circuit was invented.
Moore predicted that this trend would continue for the foreseeable future.
Currently, it is 18 - 24 months.
Most experts, including Moore himself, expect Moore's Law to hold for at least another two decades.
12. The Network Economy Gilders Law
The bandwidth of both wired and wireless networks has been continuously increasing
Follows the Gilders Law
Bandwidth grows three times as fast as the CPU speed
This trend facilitates the development of various innovative technologies, including wireless Internet access and mobile portals
13. The Network Economy Exponential Value
As the number of nodes increases linearly, the value of the network grows exponentially
The networks value is derived from plentitude
E.g., as volume of online transactions increases, the cost of every transaction diminishes
14. The Network Economy Exponential Value
Metcalfe's Law
Robert Metcalfe founded 3Com Corporation and designed the Ethernet protocol for computer networks
Metcalfe's Law states that the usefulness, or utility, of a network equals the square of the number of users
N*N N
15. The Network Economy Lifespan of Innovation
Ideas spread really fast
Hard to achieve a sustainable competitive advantage
Continuous innovation
16. The Network Economy Increasing Returns
After the dot-com crash, some individuals have become dot-com averse
Under investing vs. over investing
E.g., continuous investing in a market leader will make it stronger and weaken the competitors
17. The Network Economy Decreasing Prices
Consumers may count on superior quality for less price over time
Scientists find ways to get more out of less material
Computers, cars, electronic devices, computer memory, etc.
18. The Network Economy Information is the king!
The value of accurate and timely information increases
If you have perfect information, the best deal is guaranteed
Technology may empower the user
19. The Network Economy Information is the king!

21. The Network Economy People expect free
Freeware or at least trial versions of software programs are taken for granted
Get a product for free and pay for service or support
E.g., Java language
22. The Network Economy High Dependency
In a linked economy, the fate of an organization depends on other companies in the supply value chain, their competitors, and the external environment
Organizations have to become highly adaptive
23. The Network Economy High Rate of Displacement
The agricultural era industrial era
People have to change professions
Companies have to change product lines and restructure
24. The Network Economy Summary
Connected world
Exponential value
Lifespan of innovation
Increasing returns
Decreasing prices
Value of information
People expect free
Dependency

Foundations of Information Systems in Business Topic
26. Understand the concept of a system
Explain why IS knowledge is important
Provide examples of the components of real world systems and information systems
Explain classification of IS
Become familiar with IT careers Learning Objectives
27. Foundation Concepts Why study information systems and information technology?
Vital component of successful businesses
Helps businesses expand and compete
Improves efficiency and effectiveness of business processes
Facilitates managerial decision making and workgroup collaboration
28. Why Study IS? Does the area of MIS relate to common sense so that there is no point studying it?
High rate of MIS projects failures
Most MIS projects dont meet the deadlines and exceed the budget
Can we imagine an organization without an information system?
A great degree of expertise is required to implement IS projects or simply utilize the systems
29. System Concepts System Concepts
1. Whats a System?
2. Whats an Information System?
3. Components of an IS
4. Information System Activities
30. What is a System? A system is
A set of interrelated components
With a clearly defined boundary
Working together
To achieve a common set of objectives
By accepting inputs and producing outputs
In an organized transformation process
31. Basic Functions of a System Input
Capturing and assembling elements that enter the system to be processed
Processing
Transformation process that converts input into output
Output
Transferring transformed elements to their ultimate destination
32. Cybernetic System All systems have input, processing, and output
A cybernetic system, a self-monitoring, self-regulating system, adds feedback and control:
Feedback is data about the performance of a system
Control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goal
33. Add Feedback and Control Loops Feedback is self-monitoring
Feedback is data about the performance of a system.
Control is self-regulating
Control involves monitoring and evaluating feedback to determine whether a system is moving toward the achievement of its goals. The control function then makes necessary adjustments to a system's input and processing components to ensure that it produces proper output.
34. A Cybernetic System A home temperature control system
35. A Cybernetic System Company sales (a company is a system) decreased
Information (feedback) was sent to the sales manager
The sales manager acts (controls): reassigns salespersons, hires new salespersons, fires, changes reward structure, etc.
36. General Systems Theory Interdisciplinary science that studies structures and properties of systems
Was officially established as a scientific field in 1950s
The concepts trace back to 1600s
It is believed that a system consists of interacting components or groups of components that form a new whole
37. General Systems Theory
38. Other System Characteristics A system exists and functions in an environment containing other systems
Subsystem a component of a larger system
A larger is referred to as environment
Systems that share the same environment may be connected to one another through a shared boundary, or interface
Open versus closed system
Open interacts with other systems
Adaptive system a system that changes itself
39. Characteristics of Open Systems Input /Output Model: All systems transfer inputs into outputs. The system is viewed as a transformation process in a dynamic interaction with its environment.
Feedback and Control: The feedback of information regarding performance is used to adjust and control performance.
Interdependence: A system is composed of interrelated parts or elements
40. Characteristics of Open Systems (Conti..) Holism: The system is a whole, not merely the sum of its parts, and its performance should be viewed as an integrated system.
Goal seeking: Interaction between elements results in some final state or goal.
Steady State: The notion that systems are goal seeking implies that they are adaptive and self-regulating. It seeks a state of dynamic equilibrium.
41. Characteristics of Open Systems (Conti..) Differentiation: In complex systems, units perform specialized functions. Open systems tend to move towards increased differentiation.
Equifinality: In complex systems, an initial state may result in several possible final states, and a similar final states may be achieved from many different initial states.
Hierarchy: One system contains several other systems within it and is also a part of a large super-systems.
42. Characteristics of Open Systems (Conti..) Entropy: Open systems exchange information, energy, or material with their environment. Every transformation process involves the use of energy and resources. The tendency towards entropy is a movement towards disorder and eventually termination of functioning. To keep a system operating there must be an infusion of energy and resources.
43. A Business as a System
44. What is an Information System? An organized combination of
People
Hardware and software
Communication networks
Data resources
Policies and procedures
This system
Stores, retrieves, transforms, and disseminates information in an organization

E.g., create a backup at the end of each day, software installation instructions, email usage rules
49. Information System Resources Data Resources
Product descriptions, customer records, employee files, inventory databases
Valuable organizational resources
Data vs. Information
Data are raw unprocessed facts
Information is data converted to be useful to end users
Information is data that are
Aggregated, manipulated and organized
Its content is analyzed and evaluated
It is placed in a proper context for a human user
50. Data Versus Information
51. Data Versus Information Data resources in IS are typically organized, stored, and accessed through
Databases that hold processed and organized data. A report that is generated from the database is information
Knowledge bases that hold knowledge such as facts, rules, and case examples about successes and failures
52. Information System Resources Network Resources
Communications media twisted-pair wire, coaxial cable, microwave, cellular or other wireless technologies
Network Infrastructure
Hardware
Software
Data technologies
That are needed to support the operation and use of networks
E.g., communications processors, network access and control software
53. Information System Resources Information Resources
Management reports and business documents using text and graphics displays, audio responses, and paper forms
54. IS Activities Input of data resources
Data entry activities, e.g., optical scanning of bar-codes on tags
Processing of data into information
Calculations, comparisons, sorting, classifying, summarizing, and so on, e.g., calculating employee pay, taxes, parking deduction, etc.
Output of information products
Messages, reports, forms, graphic images, e.g., producing reports about sales performance
55. IS Activities Storage of data resources
During storage, data are retained in an organized manner for later use
Databases
Control of system performance
Monitoring and evaluating feedback about input, processing, output and storage
Adjustments to the processes may be made
E.g., total is different from subtotals correct some procedures
56. Recognizing Information Systems Business professionals should be able to look at an information system and identify
The people, hardware, software, data, and network resources they use

E.g., develop a complex AI-based system Other Competitive Strategies
85. Leverage Investment in IT
Develop products and service that would not be possible without a strong IT capability
E.g., the development of intranets and extranets enables companies to leverage their previous investment in IT infrastructure (PC, databases, networks, software, etc)
Implication: when investing in new IT, analyze its future areas of application, e.g., Is it going to be compatible with other major technologies in future? Other Competitive Strategies
86. View the firm as a chain of basic activities that add value to its products and services
Primary processes directly relate to manufacturing or delivering products
Support processes help support the day-to-day running of the firm and indirectly contribute to products or services
Use the value chain to highlight where competitive strategies will add the most value The Value Chain and Strategic IS
87. Using IS in the Value Chain
88. Strategic Uses Of Information Technology IT may be viewed as a major competitive differentiator. In this case, IT may be used for:
