Information Systems Audit

Information Systems Audit An information system audit examines and evaluates an organization’s information systems, practices, and operations. The audit is designed to confirm that the information system is safeguarding the organization’s assets, ensuring data integrity, and performing in an efficient way so as to meet the organization’s goals. Information system audit plans seek to evaluate the robustness of the organization’s information system. Is the system available at all times when needed by the organization? What are the security mechanisms in place to ensure confidentiality and security of data? Is the information provided by the systems accurate? Audits of information systems may be initiated to address these individual specific issues within the overall IS environment.

In a business context, information technology (IT) is defined as "the study, design, development, application, implementation, support or management of computer-based information systems". The prompt growth in information technology (IT) competencies and the longing of businesses of all sizes to obtain competitive advantage have led to a dramatic increase in the use of IT systems to make, process, store and communicate information.

...allow for faster system connections, staying updated with the available upgrade for the information system, faster connections to enhance business transactions, such as ordering supplies. Also, I would recommend adding a Wi-Fi connector to the system to enable customers to use their iPhones, blackberries, or droids while in the club. A Wi-Fi connection would allow consumers to place an order, which would allow the servers to spend less time running back and forth from the same table. By enabling wireless ordering one person can run the system, like an expeditor, while the other servers are seeing to the speedy delivery of the items. This is not only a benefit for the consumer but also the employees. The return on the investment for this will be significant seeing how this will allow a rise in productivity and at the same time lower costs. . When staff is to be trained on the wireless ordering system, it should be conducted by a person who is experienced in the function of the system. Although, this will cause an expenditure for the trainer and the pay of the employees, it will be minimal compared to the profitability the system will provide. The training should be offered to the employees when the club is closed, such as during the day. The training should begin with an explanation of the system and then hands-on training to allow the employees to better understand how the system will work. Next, I would recommend installing a transaction processing system (TPS) and an online...

Accounting Information System

...accountant is affected. Later in the chapter, we provide a roadmap showing you where each component is covered in this textbook. Before beginning, let us tell you two things. First, the study of AIS, is our broad view, while the accounting information system itself, is our narrow view of an AIS. Second, you shouldn’t assign any meaning to the placements of the elements in figure 1.1. The figure just tells you that there are ten elements. 1. Business Operations: An AIS operates in concert with business operations. Many AIS inputs are prepared by operating departments, the action or work centers of the organization; and many AIS outputs are used to manage these operations. Therefore, we must analyze and manage an AIS in light of the work being performed by the organization. For example, to advise his management and to prepare reports for management decision making, a management accountant must understand his organization’s business. In our scenarios, Jill had to understand corporate takeovers to prepare the relevant analysis. 2. Transaction Processing: An organization Processes Transactions, such as sales and purchase; these Transactions mirror and monitor and business operations. these Transactions have operational, management information system(MIS), and AIS aspects. To design and use the MIS and the AIS, an accountant must know what the Transactions are how they are processed, and how each transaction is recorded. For example, Jill used data collected for fixed asset transactions...

As the management is in complete know of everything transpiring in the company, it leverages on this advantageous position. Using it, a company is able to record and document all facts pertaining to its procedures and methodologies. The basic intent is to manage and control all of the company’s employees and material through MIS. Importance of Management Information System: Using an MIS, an organization is able to establish its hierarchical structure and work-flow charts. Every employee in the organization knows the employees he has authority over and to whom he is responsible for work. The work then progresses without glitches. The company’s operating and procedures are listed by an MIS. The preparation of audits also gets simplified. Benefits of Management Information System: There are numerous pluses in using an MIS. The organization records and tabulates all its key strategic functions. As and when deviations from the planned course happen, the organization is able to take corrective action at once. Communication channels are enforced. As the authority-responsibility diagrams are well established, the superiors delegate work to their subordinates and the subordinates turn to them for guidance and suggestions. The MIS mechanism enables the organization to weigh the pros and cons...

...An accounting systemThe personnel, procedures, devices, and records used by an organization to develop accounting information and communicate that information to decision makers. consists of the personnel, procedures, technology, and records used by an organization (1) to develop accounting information and (2) to communicate this information to decision makers. The design and capabilities of these systems vary greatly from one organization to another. In small businesses, accounting systems may consist of little more than a cash register, a checkbook, and an annual trip to an income tax preparer. In large businesses, accounting systems include computers, highly trained personnel, and accounting reports that affect the daily operations of every department. But in every case, the basic purpose of the accounting system remains the same: to meet the organization’s needs for information as efficiently as possible. Many factors affect the structure of the accounting system within a particular organization. Among the most important are (1) the company’s needs for accounting information and (2) the resources available for operation of the system. Describing accounting as an information system focuses attention on the information accounting provides, the users of the information, and the support for financial decisions that is provided by the information. These relationships are depicted in Exhibit 1–2. While some of the terms may not be familiar to you at this early point in your...
