1 Why study Information Systems and Information Technology?
Vital component of successful businesses Helps businesses expand and compete Businesses use IS and IT To improve efficiency and effectiveness of business processes For managerial decision making For workgroup collaboration You might just as well ask why study accounting, finance, operations management, marketing, human resources, management. Most business majors include a class in IS.

2 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 Almost everything is a system One system can be made up of other systems or can be part of a bigger system

3 What is an Information System?
An organized combination of People Hardware Software Communications networks Data resources Policies and procedures That stores, retrieves, transforms, and disseminates information in an organization This is a simple definition that we will expand upon later What’s an example? Smoke signals to transmit information Card catalogs in a library Book bag with day planner, notebooks, that allows you organize inputs from lectures, presentations and discussions. The output is homework and good exam grades Cash register at restaurant Other examples?

4 Information System (IS) versus Information Technology (IT)
IS is all the components and resources necessary to deliver information and functions to the organization IT is hardware, software, networking and data management In theory, IS could be paper based But we will focus on Computer-Based Information Systems (CBIS) Definition of IS from prior slide: An organized combination of People Hardware Software Communications networks Data resources Policies and procedures That stores, retrieves, transforms, and disseminates information in an organization In theory, an IS could be pencil and paper based

5 IS Knowledge Framework for Business Professionals

6 What should a Business Professional know about IS?
Foundation Concepts: fundamental behavioral, technical, business and managerial concepts Information Technology: Hardware, software, networks, data management and Internet-based technology Business Applications: Major uses of the IS in the organization Development Processes: How to plan, develop and implement IS to meet business opportunities Management Challenges: The challenges of effectively and ethically managing IT Refers back to figure 1.2 on prior slide Foundation Concepts: Examples: general systems theory, competitive strategies. Covered in chapters 1, 2 Information Technology: Covered in chapters 3-6 Business Applications: Chapter 7: applications in functional areas, Chapter 8: electronic commerce applications and Chapter 9: decision making Development Processes: By both business professionals and IS specialists. Chapter 10. Management Challenges: Managing IT at the end user, enterprise and global levels of a business. Chapter 11 is security challenges and Chapter 12 is how to manage IT in global businesses.

7 Fundamental Roles of IS in Business
Support of business processes and operations. Support of decision making by employees and managers. Support of strategies for competitive advantage.

8 What does IS do for a business?
Examples of business processes: record purchases, track inventory, pay employees, etc. Business would stop without such IS. Examples of decision making: what lines of merchandise need to be added, what kind of investment required. Examples of competitive advantage: put kiosk in store to connect to e-commerce website. Help gain advantage over competitor without such a kiosk.

9 Trends in Information Systems
Note that while IS has expanded, they are still doing the same basic things that they’ve been doing. What has changed is: more integration of functions, greater connectivity across components, better use for maximum advantage of business and strategic opportunities

10 What is E-business? The use of Internet technologies
to work and empower business processes, electronic commerce, and enterprise collaboration within a company and with its customers, suppliers, and other business stakeholders. An online exchange of value.

11 How e-business is being used

12 E-business use Reengineer internal business processes
Enterprise collaboration systems: support communications, coordination and collaboration among teams and work groups, e.g., virtual teams Electronic commerce: buying, selling, marketing and servicing of products and services over computer networks

13 Types of IS

14 Operations support systems
What are they? Efficiently process business transactions Control industrial processes Support communications and collaboration Update corporate databases

15 Types of Operations Support Systems
Transaction Processing Systems Record and process data from business transactions Examples: sales processing, inventory systems, accounting systems Process Control Systems Monitor and control physical processes Example: in a petroleum refinery use sensors to monitor chemical processes Enterprise Collaboration Systems Enhance team and work group communications Examples: , videoconferencing

16 Two ways to process transactions
Batch Processing: Accumulate transactions over time and process periodically Example: a bank processes all checks received in a batch at night Online Processing: Process transactions immediately Example: a bank processes an ATM withdrawal immediately

17 Management Support Systems
What are they? Provide information and support for effective decision making by managers

18 Types of Management Support Systems
Management Information Systems (MIS) Provide reports and displays to managers Example: daily sales analysis reports Decision Support Systems (DSS) Provide interactive ad hoc support for decision making Example: A what-if-analysis to determine where to spend advertising dollars Executive Information Systems (EIS) Provide critical information for executives and managers Example: easy access to actions of competitors

19 Operational or Management Systems
Expert Systems Provide expert advice Example: credit application advisor Knowledge Management Systems Support creation, organization and dissemination of business knowledge throughout company Example: Intranet access to best business practices Support either operations or management applications

20 Classifications of IS by scope
Functional business systems Focus on operational and managerial applications of basic business functions Examples: support accounting, finance or marketing Strategic information systems Help get a strategic advantage over its customers Examples: shipment tracking, e-commerce web systems Cross-functional information systems Systems that are combinations of several types of information systems Provide support for many functions In reality most systems are Cross-functional

21 Challenges and Opportunities of IT

29 IS Function represents
Major functional area of business Important contributor to operational efficiency, employee productivity, morale, customer service and satisfaction Major source of information and support for effective decision making Vital ingredient in developing competitive products and services in the global marketplace Dynamic and challenging career opportunity Key component of today’s networked business

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 Repeating definition from earlier but adding accepting inputs, producing outputs, and transformation

31 Systems have three basic functions:
Input involves capturing and assembling elements that enter the system to be processed Processing involves transformation process that convert input into output Output involves transferring elements that have been produced by the transformation process 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 towards the achievement of its goal

33 A Cybernetic system A cybernetic system has both feedback and control. A home thermostat accepts the desired room temperature as input and sends a message to fire the furnace. The thermostat provides feedback to shut the system down when the desired temperature is reached.

34 A business as a system A business can be viewed as a system. This system does not operate in a vacuum rather it functions in an environment containing other systems. A business is an open system in that it interacts with other systems in the environment. It is also an adaptive system in that it can change itself or its environment in order to survive.

35 Information systems model
Major components of an information: people, hardware, software, data and networks. These components perform input, processing, output, storage, and control activities.

36 Components of an IS People Resources Hardware Resources
End users: the people who use the IS or the information from the IS IS specialists: the people who develop and operate IS Hardware Resources All physical devices used in information processing Machines, data media, peripherals Software Resources All information processing instructions including programs and procedures System software, application software and procedures Hardware: Peripherals include keyboard, mouse, video screen, printer

37 Components of an IS (cont.)
Data Resources Facts about the business transactions Processed and organized information Databases of organized data Network Resources Communications media Network infrastructure: hardware and software The Internet, intranets and extranets Communications media: twisted pair wire, coaxial cable, wireless technologies

38 Data versus Information
Data are raw facts about physical phenomena or business transactions Information is data that has been converted into meaningful and useful context for end users Example: Sales data is names, quantities and dollar amounts Sales information is amount of sales by product type, sales territory or salesperson

39 IS Activities Input of data resources
Data entry activities Processing of data into information E.g., calculate, compare, sort, classify, summarize Output of information products Messages, reports, forms and graphic images Storage of data resources Data elements and databases Control of system performance Monitoring and evaluating feedback

40 Recognizing IS As a business professional, you should be able to look at an IS and identify The people, hardware, software, data and network resources they use The type of information products they produce The way they perform input, processing, output, storage and control activities
