the problem of providing students a comprehensive, but interesting knowledge base of AIS However, we all know that it is difficult to find the right balance of coverage of technical concepts and student comprehension When addressing this issue of balance, we began to see clearly that a better, more comprehensible approach was needed With this book, we have achieved a good balance of covering technical concepts while still making the text easy to read and understand Our textbook also reinforces AIS concepts with relevant, real‐world examples and reasonable end‐of‐chapter materials This text incorporates the important content found in a typical AIS course, but has five distinguishing characteristics Five characteristics we focus on throughout the text are simplicity and understandability of the writing, business processes, accounting and IT controls, examples from Microsoft Dynamics GP (an ERP/AIS system), and ethics as it relates to accounting systems We place extra emphasis on the students’ understanding We explain AIS in the context of business processes and incorporate many real‐world examples The richness of these examples improves the text, the discussion questions, and end‐of‐chapter exercises and cases We explain IT controls by employing the framework in the AICPA Trust Services Principles This is an encompassing, but easy to understand, framework of IT controls We provide examples in the text of an AIS/ERP system, Microsoft Dynamics GP Instructors are able to add a hands‐on learning of Microsoft Dynamics GP that complements the theoretical concepts in the text Finally, we believe that ethics continues to increase in importance as a topic to be included in accounting texts We have included an ethics section in each chapter We think that including all these characteristics in a single text has resulted in an extremely user‐friendly product: one that will help your students achieve a better foundation in AIS Features The book is designed to enhance student learning with a focus on ease of use, business processes and the related controls, and ethics and corporate governance as they relate to accounting information systems (AIS) Ease of Use This AIS textbook will allow students to easily read and comprehend the material, understand the charts and graphs, and successfully answer questions and cases at the end of the chapters To attain ease of use, we included several features, including the following: • An approach to technical topics with a writing style that is easy to understand vii www.freebookslides.com viii Preface • Process maps and document flowcharts that provide a picture of business processes and that are easy to understand While there are several approaches to charts that depict systems, we have used the types of charts that illustrate business processes in the simplest, yet complete manner Especially in the chapters focused on business processes, we use matched process maps, document flowcharts, and data flow diagrams to illustrate the processes that occur, and the related flow of information and documents These charts are easy to follow and they will enhance the understanding of the business processes • AICPA Trust Services Principles framework for IT controls Controls within Information Technology can be a very difficult subject to comprehend because of the underlying complexity of the technology While COBIT is the most comprehensive source of IT control information, it is not typically easy for students to understand This is especially true for students who have not had the opportunity to gain work experience with IT systems and business processes We use the simplest framework available for the explanation of IT controls: the AICPA Trust Services Principles The Trust Services Principles categorize IT Controls into five areas: security, availability, processing integrity, online privacy, and confidentiality • Control and risk tables that summarize internal controls and the related risks Internal controls are easier to understand when students can see the corresponding types of risks that the controls are intended to lessen We use control/risk exhibits to present risks that are reduced when controls are used • Real‐world examples to illustrate important concepts Concepts are often easier to comprehend when presented in a real‐world scenario Each chapter includes examples of issues faced by actual business organizations that help illustrate the nature and importance of concepts in the chapter Real‐world discussions are boxed in a feature titled “The Real World.” • Microsoft Dynamics GP screen shots to present topics in the context of a real computer system New concepts are often easier for students to understand while presented within a real‐life application We use screen shots from Microsoft Dynamics GP software to show how various aspects of business processes would appear in this computer system In addition, in this version, we have added the ability for instructors to add hands‐on learning of Microsoft Dynamics GP to the coursework See the textbook website for details This add‐on tool provides access to a cloud‐based version of Microsoft Dynamics minimizing the involvement of a university’s IT staff • The IT technology that underlies AIS continually evolves and allows enhancements to those systems Several chapters integrate the concept of cloud computing and the increasing use of cloud computing The effects of cloud computing on the risk benefits and auditing in AIS are also described • End‐of‐chapter questions, problems, and cases that match well with the chapter content It is important to provide material at the end of each chapter that helps students reinforce the topics presented It is equally important that this material be relevant and understandable We have devoted our attention to providing a variety of end‐of‐chapter activities that are meaningful and manageable, including a concept check, discussion questions, brief exercises, Web exercises, problems, cases, and a continuing case In addition, most chapters include activities adapted from professional (CPA, CMA, and CIA) examinations Business Processes, Accounting Controls, and IT Controls Business transactions are portrayed within the text in terms of business processes, which are widely recognized throughout the accounting profession These business processes are described in a manner that is applicable to many different business environments www.freebookslides.com INDEX 545 General controls for IT systems,

Online Data Storage Off-page Connector Decision Terminator (beginning or end) File www.freebookslides.com PROCESS MAP SYMBOLS An oval is used to show the start and/or finish of a process The start is usually the input of the business process, and the finish is the output The input and output may be materials, activities, or information A rectangle shows a task or activity in the process Typically, only one arrow comes out of a rectangle (one output) However, many arrows can come into a rectangle (inputs) A diamond represents a point in the process when a decision must be made In many cases the decision is a yes/no decision, but not always An arrow shows the direction of flow within the process A A circle with a letter or number inside is used as a connector A connector is used when there is a break in the process The connector is used at the beginning of the break in the process, and again where the process resumes DATA FLOW DIAGRAM SYMBOLS A square is a terminator It represents both sources and destinations of data A rectangle with rounded corners represents a process Any tasks or functions performed are depicted by this rectangle An open-ended rectangle is a data store or the storage of data Storage could be in manual records or computer files An arrow shows the direction of flow of data www.freebookslides.com A LIST OF FLOWCHARTS IN THIS TEXTBOOK Exhibit Page Title
