1 Accounting Information Systems: An Overview

2 Presentation Outline The Users of Accounting Information
Information Systems Transaction Processing Cycles The Internal Control Process Organization Interaction with Information Systems The Development of Systems

3 I. The Users of Accounting Information
External Users of Accounting Information Internal Users of Accounting Information Mandatory vs. Discretionary Information

4 A. External Users of Accounting Information
Creditors Investors Stockholders Customers and Vendors Government Agencies

5 B. Internal Users of Accounting Information
Lower Level Managers Middle Managers Top-Level Managers Characteristic of Information Operational Control Management Control Strategic Planning Source Largely internal External Level of Aggregation Detailed Aggregate Time Horizon Historical Future Required Accuracy High Low

6 C. Mandatory vs. Discretionary Information
Mandatory Information Certain types of information must be generated regardless of the cost: Government reports Payroll Basic bookkeeping Evaluation Criteria For mandatory information, the primary concern is minimization of cost. In contrast, discretionary information should provide greater benefits than the cost of generating it.

7 II. Information Systems
The term information system suggests the use of computer technology in an organization Hardware Software Information System Information for Decision Making Data Electronic Data Processing (EDP) or Data Processing (DP) Management Information Systems (MIS) Decision Support Systems (DSS) Expert Systems (ES) Executive Information Systems (EIS) Accounting Information Systems (AIS) Information systems can be manual or computerized. A “computer-based” system is a collection of computer hardware and software designed to transform data into useful information.

8 A. Electronic Data Processing (EDP) or Data Processing (DP)
Use of computer technology to perform an organization’s transaction-oriented data processing. DP systems serve routine, recurring, general information needs.

9 B. Management Information Systems (MIS)
Use of computer technology to provide managers with decision-oriented information beyond what a normal DP system provides. Subsystems include: Marketing information system Manufacturing information system Human resource information system Financial information system Functional MIS subsystems provide a logical rather than physical way of implementing the MIS concept in organizations.

10 C. Decision Support Systems (DSS)
Processes data into a decision making format for end users. Decision support systems (DSS’s) process nonroutine information requests on an ad hoc basis. Requires the use of decision models and specialized databases beyond what is in a DP system.

11 Inference engine – process by which expert makes the decision.
D. Expert Systems (ES) I know the answer. Emulates an experts decision making process to provide a decision. Different from DSS which only provides information for making a decision. Two components of the ES are as follows: Knowledge base – special knowledge that an expert possesses in the decision area. Inference engine – process by which expert makes the decision.

12 E. Executive Information System (EIS)
Executive information systems tailor information to the strategic needs of top-level management. Much of the information used by top-level management comes from sources outside the organizations information system. (i.e., meetings, memos, television, periodicals, and social activities). Which direction?

13 F. Accounting Information Systems (AIS)
A computer-based system designed to transform accounting data into information. Can also include transactions processing cycles, the use of information technology, and the development of information systems.

14 III. Transaction Processing Cycles
The transaction processing cycles provide a means of viewing the activities of a business. Revenue Cycle Expenditure Cycle Production Cycle Finance Cycle Financial Reporting Cycle

15 A. Revenue Cycle Events related to the distribution of goods and services to other entities and the collection of related payments

16 B. Expenditure Cycle Events related to the acquisition of goods and services from other entities and the settlement of related obligations.

17 C. Production Cycle Events related to the transformation of resources into goods and services.

18 D. Finance Cycle Events related to the acquisition and management of capital funds, including cash. The treasurer is responsible for the finances of the business.

19 E. Financial Reporting Cycle
Not an operating cycle This cycle obtains accounting and operating data from other cycles and processes this data so that financial reports can be prepared. A controller is in charge of the accounting function.

20 IV. The Internal Control Process
Since management is far removed from the scene of operations in a large organization, personal supervision of employees is often replaced with various control techniques. Definition of Internal Control The Five Elements of the Internal Control Process Segregation of Accounting Functions The Internal Audit Function

21 A. Definition of Internal Control
Internal control is a process designed to provide reasonable assurance regarding the achievement of objectives relating to: Reliability of financial reporting Effectiveness and efficiency of operations Compliance with applicable laws and regulations The concept of internal control structure is based on two major premises: management’s responsibility and reasonable assurance.

22 B. Five Elements of the Internal Control Process
Control environment – Overall values and integrity of organization. Risk assessment – Identification and evaluation of risks (Potential loss x Probability = Exposure). Control activities – Activities undertaken to reduce probability of loss due to significant risks. Information and communication – Communicating information about the control environment and control activities. Monitoring – Keeping watch over and changing internal controls so that they function effectively and efficiently.

23 C. Segregation of Accounting Functions
I kept the records and the cash. Segregate the following duties: Authorization Record keeping Custody of assets

24 D. Internal Audit Function
Internal auditing is an independent appraisal function charged with monitoring and assessing compliance with organizational policies and procedures.

25 V. Organization Interaction With Information Systems
The Steering Committee End-User Computing Quick-Response Technology

26 A. The Steering Committee
A committee advising the Chief Information Officer that is composed of high-level members of user functions such as manufacturing and marketing. The committee provides a means by which managers from other areas can influence the information services process.

27 B. End-User Computing (EUC)
Functional end users do their own information processing activities through an EUC application such as a database that uses a query language feature to generate specific information needed by the end user to make decisions. (See Fig. 1.7 on p. 13) Potential EUC Problems Inadequate system development – May solve wrong problem or have poor documentation. Ineffective use of resources – Underutilized equipment or inefficient design. Data integrity and security problems – Inadvertent alteration of data or failure to implement security controls. See contrast to traditional approach in Figure 1.8 on page 14.

28 C. Quick-Response Technology
Just-In-Time Web Commerce Electronic Data Interchange Extensible Business Reporting Language Computer Integrated Manufacturing Electronic Payment Systems

29 1. Just-in-Time Purchase orders for inventory items are made on a “demand-pull” basis rather than a fixed interval “push” basis to restock store inventory levels. Adds flexibility to meet customer needs and reduces product rework.

30 Provides worldwide availability of products on a single computer.
2. Web Commerce Provides worldwide availability of products on a single computer. Specially trained CPAs offer the Web Trust seal to sites that meet certain security and privacy criteria.

31 3. Electronic Data Interchange
Electronic data interchange (EDI) is the direct computer-to-computer exchange of business documents via a communications network. EDI differs from in that EDI messages are created and interpreted by computers without human intervention. Also makes use of universal product code (UPC) bar code. (See Fig on p. 15)

32 4. Extensible Business Reporting Language
Extensible Business Reporting Language (XBRL) is a language that facilitates the exchange over the Internet of all kinds of business documents and financial statements. The SEC permits companies to file their financial reports electronically using XBRL format.

33 5. Computer-Integrated Manufacturing (CIM)
Components of CIM typically include computer-aided design (CAD) workstations, real-time production monitoring and control systems, and order inventory and control systems. Makes use of scanner technology and machine-readable bar codes.

34 6. Electronic Payment Systems
Electronic funds transfer (EFT) systems are electronic payment systems in which processing and communication are primarily or totally electronic.

35 VI. The Development of Systems
Blueprinting Systems Development Behavioral Considerations

36 A. Blueprinting The company uses generic or industry standard stock blueprints rather than designing its own system.

37 The Result of Poor Systems Development
B. Systems Development A systems development project ordinarily consists of three phases: systems analysis, systems design, systems implementation. The procedure attempts of improve information quality, internal control, and minimize cost. The systems approach consists of six steps: The Result of Poor Systems Development Statement of system objective(s) Creation of alternatives Systems analysis Systems design Systems implementation Systems evaluation User cooperation to operate the system should be insured during the design of a system, not afterward. Personnel training should also occur at this time rather than being initiated after the system is installed.

38 C. Behavioral Considerations
The users of systems should be included throughout the steps of systems development. Users provide valuable input into what is needed and must accept the system that is developed.

39 Summary Five Types of Information Systems
Five Transaction Processing Cycles The Internal Control Process Steering Committee and EUC Quick-Response Technology The Steps of Systems Development EDP, MIS, DSS, ES, AIS Revenue, Expenditure, Production, Finance, Financial Reporting Achievement of objectives relating to: reliability of financial reporting, effectiveness and efficiency of operations, compliance with applicable laws and regulations. Steering Committee and End-User Computing The Importance of Systems Development Statement of systems objectives Creation of alternatives Systems analysis Systems design Systems implementation Systems evaluation
