Preface
Welcome to the distance mode offering of Computer Science G, Introduction to Management Information Systems. This text was written with the aim of introducing the concepts of Management Information Systems. Management Information Systems (MIS) is the application of information technology to organizational and managerial needs. After reading and doing the SAQs and activities in this text, you should already be aware of what information technology can contribute to an organization and how to bring that solution to fruition. Your strength after taking this course lies in your ability to apply the knowledge of information systems and technology to help organizations compete more successfully in the marketplace or to streamline current operations. Here you will be trained to utilize your business-based backgrounds in working with managers and users to specify technology needs that benefit the organization. Another skill expected of you after this course is to be able to analyze and implement enterprise-wide solutions to information problems and manage telecommunications efforts. You might also be expected to know how to implement and manage corporate-wide information systems projects. Gee! It seems that there are a lot of things expected of you. Well, the idea of this course is to introduce you to the concepts of MIS. Learning MIS does not usually occur after doing a semester course. You have to practice it in your organization and apply what you learned. As you go along, you become more experienced and learning should become faster due to the correct foundation provided by this course. Good luck and I encourage you to allocate enough time for this course. For any comments and corrections, please contact one of the authors using the address below.
