Accounting Systems and Subsystems
• A system is a set of interdependent elements that together accomplish specific objectives.
• A subsystem is the interrelated parts that have come together, or integrated, as a single system, which we have named System 1.0.

Information System Model
• An information system (IS) or management information system (MIS) is a manmade system that consists of an integrated set of computer-based and manual components established to collect, store, and manage data and to provide output information to users.
• The figure on the next slide depicts the functional components of an information system.

Purpose of AIS
• Collect, process and report information related to the financial aspects of business events.
• Often integrated and indistinguishable from the overall information system.
• Like the IS, the AIS may be divided into components based on the operational functions supported.

1. Management hires personnel and establishes the means foraccomplishing
the work of the organization.

2. Management establishes broad marketing objectives and assigns specific sales quotas by which progress toward the long-run objective can be measured. In addition, management designs the IS procedures for facilitatingoperations, such as the procedures used to pick and ship goods to thecustomer.

5. The IS sends a request to the warehouse to ship goods to the customer. This request identifies the goods and their location in the warehouse.
18

Management Problem Structure and Information Requirements

Management Problem Structure and Information Requirements
• Horizontal flows relate to specific business events, such as one shipment, or to individual inventory items. The information moves through operational units such as sales, the warehouse, and accounting.
• Vertical flows relate to the flow of information to and from strategic management through tactical management, operations management, and operations and transaction processing.
31
Accountant’s Role in Current Business Environment
• Designer — application of accounting principles, auditing, information systems, and systems development.
• User — participate in design.
• Auditor — provide audit and assurance services.
