  2. COURSE DESCRIPTION Catalog Description For current and potential engineering and technology managers. Knowledge of information systems and technology to lead the specification, selection, implementation, and integration of information technology in manufacturing and service organizations. Management issues involved in the use of information technology in organizations. Prerequisites Graduate standing or consent of instructor.

  3. COURSE OBJECTIVES • To develop an awareness of modern information systems concepts, such as database architectures, computing architectures, application architectures, the Internet, and Intranets, and their impact on organizational performance. • To identify the different phases in the design, development, implementation, and maintenance of effective information systems. • To understand the basics of content creation, management, and distribution.

  4. COURSE OBJECTIVES • To understand and evaluate commercially available systems and solutions for data management and report generation. • To develop an understanding of the technical and human issues involved in managing, controlling, and administering information technologies. • To explore “new” organizational structures (e.g. virtual corporations) resulting from the use of modern information systems and technology.

  8. GRADING POLICY Method of Instruction Two seventy-five minute class periods per week. Class will consist of lecture and discussion. Grading Policy Graded work will be weighted as follows: Mid-term Examination 20% Homework (8-10 sets) 30% Term Paper 25% Final Examination 25%

  9. GRADING POLICY • Grades will be given on a 90, 80, 70, 60 basis. The instructor reserves the right to lower the curve as circumstances warrant. • Homework assignments are expected to be well organized and neatly presented. They will be graded and returned to the student. • Academic dishonesty will not be tolerated. When the instructor feels beyond reasonable doubt that dishonesty has occurred, he will take disciplinary action in accordance with university policies and procedures. • Spring Syllabus Attachment • www2.okstate.edu/acad/sylatsp00.html

  13. INFORMATION SYSTEMS An arrangement of people, data, processes, interfaces and geography that are integrated for the purposes of supporting and improving the day-to-day operations in a business, as well as fulfilling the problem-solving and decision-making information needs of business managers Source: Whitten, J.L. and L.D. Bentley(1998), Systems Analysis and Design Methods, pp. 38, Fourth Edition Irwin McGraw-Hill, Boston

  14. MAIN IDEA DISCUSSED BY ZACHMAN • There is a set of architectural representations produced over the process of building a complex engineering product representing the different perspectives of the different participants.

  15. INFORMATION SYSTEM PERSPECTIVES S Y S T E M A N A L Y S T S System Owners INFORMATION SYSTEM SCOPE (purpose and vision; goals and objectives; costs and benefits) System Users INFORMATION SYSTEM REQUIREMENTS (WHAT the system “is” and “must do” independent of technology) System Designer INFORMATION SYSTEM DESIGN (HOW the system will be implemented using technology) System Builders INFORMATION SYSTEM COMPONENTS (the actual, technical implementation of the system) Source: Whitten, J.L. and L.D. Bentley(1998), Systems Analysis and Design Methods, Fourth Edition Irwin McGraw-Hill, Boston

  16. CLASSIFICATION OF STAKEHOLDERS • System owners pay for the system to be built and maintained • System users are the people who actually use the system to perform or support the work to be completed • System designers are the technical specialists who design the system to meet the customer requirements • System builders are the technical specialists who construct, test and deliver the system into operation

  17. MAIN IDEA DISCUSSED BY ZACHMAN • The same product can be described, for different purposes, in different ways, resulting in different types of descriptions.

  18. DIFFERENT DESCRIPTIONS OF THE SAME PRODUCT • Material description: It talks about WHAT the thing is made of • Functional Description: It talks about HOW the thing works • Location Description: It talks about WHERE the flows exist

  19. I/S ANALOGS FOR THE DIFFERENT DESCRIPTIONS

  20. FOCUSES • DATA: the raw material used to create useful information • PROCESSES: the activities that carry out the mission of the business • INTERFACES: how the system interacts with people and other systems • GEOGRAPHY: where the data is captured and stored; where the processes happen; where the interfaces happen

  23. WHITTEN-BENTLEY’S ADAPTATION OF ZACHMAN’S FRAMEWORK System Data System Processes System Interfaces System Geography Methodology S Y S T E M A N A L Y S T S System Designer Database Schema Translation of data requirements into databases Application Schema Implementa- tion of bus.processes using computers Interface Schema Properties, system states, events and their responses Network Schema Model indentifying all centers involved in an application Configuration Phase System Builders Database Programs Closest to database technology foundation Application Programs Language based representation of what a process should do Component Programs GUIs - Visual BASIC Delphi Powerbuilder Network Programs Machine readable specifications of computer communication parameters Construction Phase

  24. INTERESTING FEATURES OF THE FRAMEWORK • Each element on either axis of the matrix is explicitly differentiable from all other elements on that one axis. • These representations are not merely successive levels of increasing detail but are actually different representations.
