3. Information Technology (IT) Computer Technology (Hardware and Software) Processing and Storing Information Communication Technology Transmitting information

5. CIS 300 - MIS The MIS Concept Why Studying IS/MIS What You Need to Know System Concepts Types of Business Information Systems Roles; Trends RolesTrends Managerial Challenges of IT Course Website

6. The MIS Concept The MIS concept addresses the use of IT to improve individual and organizational performance at two levels: 1)producing better tangible outputs 2)developing tools and processes that allow better management decision making

7. Level 1: Better Tangible Outputs IT is used to make the process in producing a tangible output more efficient and more effective Implication Issues whether or not to use IT selecting the proper IT employing correct procedures for the utilization of the IT

8. Level 2 : Intangible Outputs A schematic view - the information/decision levelA schematic view MIS involves identifying the key decisions that are related to reaching objectives, on determining the proper information needed to make these decisions, and on improving the decision processes employed to make the decisions. Implications: Activity at this level concentrates on developing tools and processes that allow better management decision making

9. The MIS Concept - Level 2: Intangible Outputs (achieving desired objectives)

10. System Concepts What is a system? A set of components that interact to accomplish goals Systems can be viewed as process models in terms of their inputs, outputs, processing, and feedback/control mechanisms. Examples.Examples What is an IS? A set of interrelated components that collect input, process, and output data and information and provide a feedback/control mechanismcollect input, process, and output data and information and provide a feedback/control mechanism What is a CBIS? An IS that uses IT. Components: hardware, software, databases, networks, people, proceduresprocedures

11. System Examples University – an example Inputs: students, faculty, textbooks Processing mechanisms: teaching, research, service Output: graduates Goal: acquisition of knowledge The Manufacturing System Other Examples Subsystem, interface, open, adaptive BoundaryFeedback

12. Manufacturing Process Input of Raw Materials Output of Finished Products Environment Other Systems Control by Management Control Signals Control Signals Feedback Signals Feedback Signals System Boundary A Manufacturing System: Generic Components

13. Systems: Some Examples University Inputs: Students, Faculty, Textbooks Processes: Education/Courses Output: graduates Feedback: surveys, grades Toyota Plant Inputs: raw materials, components Processes: assembly line Output: mini-vans Feedback: customer surveys, quality reports Fast Food IS Inputs: consumer orders Processes: processing software Output: receipts, cooks order list Feedback: invalid entry message Video Store IS Inputs: rentals, returns Processes: processing software Output: reports, rental agreement Feedback: error repots

14. System Classifications and Characteristics OpenClosedAdaptiveNonadaptive Subsystem System Boundary Interface Open, Adaptive Systems

15. Input, Processing, Output, Feedback/Control INPUTS Gathering and capturing raw data PROCESSING Converting or transforming data into useful outputs OUTPUTS Producing useful information, usually in the form of documents. Feedback/Control Output that is used to make changes to input or processing activities

16. Procedures Procedures - set of instructions used by people to complete a task Procedures include the strategies, policies, methods, and rules for using the CBIS. Examples: procedures describe When each program is to be run Who can have access to database What is to be done in case of a disaster

17. System Performance Standards: Efficiency and Effectiveness Efficiency: a measure of what is produced divided by what is consumed an improved product the same level product produced cheaper or faster the improvement in the product exceeds the increased cost Effectiveness: a measure of the extent to which a system achieves its goals. Goal: to reduce damaged parts by 100 units Q: Actual reduction in damaged parts using a control system is only 85 units. Effectiveness? A: The effectiveness of the control system is 85 percent

18. What You Need to Know Foundation Concepts: Fundamental concepts about the components and roles of IS IT: Major concepts, developments, and management issues in information technologies Business Applications: The major uses of IS for the operations, management, and competitive advantage Development Processes: How end users or information specialists develop and implement IS The challenges of effectively and ethically managing information technologies, strategies, and security at the end user, enterprise, and global levels of a business

19. Major Roles of Information Systems Support of Strategic Advantage Support of Managerial Decision Making Support of Business Operations

23. What uses of IT might be considered improper, irresponsible, or harmful to other individuals or to society? What is the proper use of an organizations information resources? What does it take to be a responsible end user of IT? How can you protect yourself from computer crime and other risks of IT? Ethical Dimensions of IT
