Education in information systems is critical for workers in every discipline. Today,information systems are used for business processes from communications to order processing to customer support and in business functions ranging from marketing to human resources to accounting and finance. Chances are, regardless of your future occupation, you need to understand what information systems can and can-not do and be able to use them to help you accomplish your work. You may even be asked to suggest new uses for information systems and participate in the design of solutions to business problems employing information systems. You will be chal-lenged to identify and evaluate information systems options. To be successful, you must be able to view information systems from the perspective of business and organizational needs. For your solutions to be accepted, you must identify and address their impact on fellow workers, customers, suppliers, and other key busi-ness parmers. For these reasons, a course in information systems is essential forstudents in today's high-tech world.
　　Principles cf Information Systems: A Martagerial Approach, Sixth Edition, continues the tradition and approach of the previous editions. Our primary objective is to provide the best information systems text and accompanying materials for the first information technology course required of all business students. Through survets, questionnaires, focus groups, and feedback that we have received from current and past adopters, as well as others who teach in the field, we have been able to develop the highest-quality set of teaching materials available.
　　Principles of Information Systems: A Managerial Approach, Sixth Edition, stands proudly at the beginning of the IS curriculum and remains unchallenged in its position as the only IS principles text offering the basic IS concepts that every business student must learn to be successful. In the past, instructors of fiae intro ductory course faced a dilemma. On one hand, experience in business organiza tions allows students to grasp the complexities underlying important IS concepts.
　　For this reason, many schools delayed presenting these concepts until students completed a large portion of the core business requirements. On the other hand,delaying the presentation of IS concepts until students have matured within the business curriculum often forces the one or two required introductory IS courses to focus only on personal computing software tools and, at best, merely to introduce computer concepts.
　　This text has been written specifically for the principles course in the IS curriculum. Principles of Information Systems: A Managerial Approach, Sixth Edition,treats the appropriate computer and IS concepts together with a strong manage rial emphasis.
