Learning Objectives Appreciate the complex, dynamic environment in which
accounting is practiced. Know the relationship between the AIS and the
organization’s business processes. Know the attributes of information. Recognize how information is used for different types of
decisions and at various levels in the organization. Recognize how the information system supports the
management function. Recognize the accountant’s role in relation to the current
environment for the AIS.

Systems and Subsystems System: a set of interdependent elements
that together accomplish specific objectives. A system must have organization, interrelationships, integration, and central objectives.
Subsystem: a part of a system. Within limits, any system or subsystem can be divided into its component parts.

The Information System (IS)An information system (IS) or
management information system (MIS) is a man-made 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.

Functional Model of an Information System
![Page 14: Accounting Information System ch 01 ppt1](https://reader036.vdocuments.us/reader036/viewer/2022081511/5541eda3550346b90e8b45b0/html5/thumbnails/14.jpg)

The Accounting Information System (AIS)Accounting information system (AIS) is a
specialized subsystem of the IS.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. Components are called business processes or AIS subsystems.
![Page 15: Accounting Information System ch 01 ppt1](https://reader036.vdocuments.us/reader036/viewer/2022081511/5541eda3550346b90e8b45b0/html5/thumbnails/15.jpg)
Three Business Process Components Information process: portion of the overall IS
related to a particular business process. Operations process: man-made system
consisting of the people, equipment, organization, policies, and procedures whose objective is to accomplish the work of the organization.
Management process: man-made system consisting of the people, authority, organization, policies, and procedures whose objective is to plan and control the operations of the organization.

Management Problem Structure and Information Requirements
![Page 24: Accounting Information System ch 01 ppt1](https://reader036.vdocuments.us/reader036/viewer/2022081511/5541eda3550346b90e8b45b0/html5/thumbnails/24.jpg)
Structure of DecisionsStructured decisions: those for which all
three decision phases (intelligence, design, and choice) are relatively routine or repetitive.
Unstructured decisions: those for which none of the decision phases (intelligence, design, or choice) are routine or repetitive.

Horizontal and Vertical Information FlowsHorizontal information 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 information flows service a multi-level management function from operations and transaction processing through tactical, operations, and strategic management.
