Slide 2:Several Terms

E-World; Digital Age; Digital Firms Information Technology (IT) Information Systems (IS) Office Workers; Knowledge Workers; End-Users; End-User Managers E-Business; E-Commerce Business initiatives drive IT choices

Slide 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 Managerial Challenges of IT Course Website

Slide 6:The MIS Concept

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

Slide 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

Slide 8:Level 2 : Intangible Outputs

A schematic view - the information/decision level 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

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

Slide 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. What is an IS? A set of interrelated components that collect 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, procedures

Slide 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 Boundary Feedback

Slide 12:A Manufacturing System: Generic Components

Slide 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, cook�s order list Feedback: invalid entry message Video Store IS Inputs: rentals, returns Processes: processing software Output: reports, rental agreement Feedback: error repots

Slide 14:System Classifications and Characteristics

Subsystem System Boundary Interface Open, Adaptive Systems

Slide 15:Input, Processing, Output, Feedback/Control

Output that is used to make changes to input or processing activities

Slide 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

Slide 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

Slide 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

Slide 19:Major Roles of Information Systems

Slide 20:History of the Role of IS

Slide 21:Trends in ISs

Data Processing: 1950s - Transaction processing, record keeping, traditional accounting applications Management Reporting: 1960s - MIS � predefined management reports for decision-making purposes Decision Support: 1970s - DSS � interactive ad hoc support of the managerial decision-making process Strategic and End User Support: 1980s - EUC, Executive Information Systems, Expert Systems, Strategic Information Systems Electronic Business and E-Commerce: 1990s -
