The ninth edition of Accounting Information Systems stresses electronic commerce applied within the context of business processes, transaction cycles, and internal control. Detailed material on business processes and internal control is central to the topical organization. The business process chapters are SAPTM-oriented and rely on SAP concepts to illustrate contemporary ERP systems. However, these chapters do not require the instructor to possess technical expertise in SAPTM. The detailed material on internal controls in these chapters is consistent with other, non-SAP, approaches to ERP There is an extensive CPA examination problem set pertaining to business processes and internal controls, with complete answers and explanations in the Instructor's Manual. The ninth edition has three fewer chapters than the eighth edition. This has been done to emphasize the textbook's core coverage of business processes, transaction cycles, and internal controls. These topics have been central to this textbook since its original publication in 1980. The recent passage of the Sarbanes-Oxley Act is a testament to the continuing importance of these topics. An understanding of business processes is fundamental to contemporary auditing, professional, and legal considerations relating to an organization's internal control processes. Each process is subject to loss exposures. Management should develop detailed control objectives for each process. Such control objectives provide a basis for analysis and audit of an organization's internal control processes as well as a basis for managing the loss exposures that are associated with an organization's dependence on information systems. Each chapter contains the following instructional aids: Learning Objectives Glossary Chapter Quiz Review Questions The chapters in Part I survey information technology, systems techniques, electronic commerce, internal control, and computer security.
