Internal & External Information Flows
3Internal Information Flows
Horizontal flows of information used primarily at the operations level to capture transaction and operations dataVertical flows of information
downward flows — instructions, quotas, and budgets
upward flows — aggregated transaction and operations data

Information Objectives
The goal of an information system is to support
To support the stewardship function of management,
To support management decision making, and
To support the firm’s day-to-day operations.

What is an Information System?
An information system is the set of formal procedures by which data are collected, processed into information, and distributed to users.6
Transactions
A transaction is a event that affects or is of interest to the organization and is processed by its information system as a unit of work.Financial transactions
economic events that affect the assets and equities of the organization
e.g., purchase of an airline ticket
Nonfinancial transactions
all other events processed by the organization’s information system
e.g., an airline reservation — no commitment by the customer

What is an Accounting Information System?Accounting is an information system.
It identifies, collects, processes, and communicates economic information about a firm using a wide variety of technologies.
It captures and records the financial effects of the firm’s transactions.
It distributes transaction information to operations personnel to coordinate many key tasks.

AIS versus MIS
Accounting Information Systems (AIS) process
financial transactions; e.g., sale of goods
nonfinancial transactions that directly affect the processing of financial transactions; e.g., addition of newly approved vendors
Management Information Systems (MIS) process
nonfinancial transactions that are not normally processed by traditional AIS; e.g., tracking customer complaints
10
AIS versus MIS?
11AIS Subsystems
Transaction processing system (TPS)supports daily business operations
General Ledger/ Financial Reporting System (GL/FRS)
produces financial statements and reports
Management Reporting System (MRS)
produces special-purpose reports for internal use

General Model for AIS
Data Sources
Data sources are financial transactions that enter the information system from internal and external sources.External financial transactions are the most common source of data for most organizations.
E.g., sale of goods and services, purchase of inventory, receipt of cash, and disbursement of cash (including payroll)
Internal financial transactions involve the exchange or movement of resources within the organization.
E.g., movement of raw materials into work-in-process (WIP), application of labor and overhead to WIP, transfer of WIP into finished goods inventory, and depreciation of equipment

Transforming the Data into Information
Functions for transforming data into information according to the general AIS model:1. Data Collection
2. Data Processing
3. Data Management
4. Information Generation

Characteristics of Useful Information
Regardless of physical form or technology, useful information has the following characteristics:Relevance: serves a purpose
Timeliness: no older than the time period of the action it supports
Accuracy: free from material errors
Completeness: all information essential to a decision or task is present
Summarization: aggregated in accordance with the user’s needs
20
Organizational Structure
The structure of an organization helps to allocateresponsibility
authority
accountability
Segmenting by business function is a very common method of organizing.
21
Functional Segmentation
Materials Management
purchasing, receiving and stores
Production
production planning, quality control, and maintenance
Marketing
Distribution
Personnel
Finance
Accounting
Information Technology
22
Accounting Independence
Information reliability requires accounting independence.Accounting activities must be separate and independent of the functional areas maintaining resources.
Accounting supports these functions with information but does not actively participate.
Decisions makers in these functions require that such vital information be supplied by an independent source to ensure its integrity.
23
IT: Data Processing
24Centralized Data
Processing
Distributed Data
Processing
Most companies fall in between.
All data processing
is performed by
one or more large
computers housed
at a central site
that serves users
throughout the
organization.
Primary areas:
database administration
data processing
systems development
systems maintenance
Reorganizing the
computer services
function into small
information processing
units that are distributed
to end users and
placed under their control
Distributed Data Processing Model
Accountants’ Unique Roles in AIS
Accountants must be able to clearly convey their needs to the systems professionals who design the system.The accountant should actively participate in systems development projects to ensure appropriate systems design.
26
Accountants as System Designers
Accountants are the domain experts and responsible for the conceptual design of the AIS.
Conceptual system design involves specifying the criteria for identifying delinquent customers and the information that needs to be reported.
As the domain expert, the accountant determines the nature of the information required, its sources, its destination, and the accounting rules that need to be applied.
27
Accountants as System Auditors
External (Financial) AuditsInternal Audit
Fraud Audit
28
External (Financial) Audit
Independent attestation regarding the fairness of the presentation of financial statementsTwo types of evidence
Tests of controls
Substantive tests
29
Attest Service versus Advisory Services
SOX restricts non-audit services to clients. Auditor may not provide:bookkeeping or other services related to the accounting records or financial statements of the audit client
financial information systems design and implementation
appraisal or valuation services, fairness opinions, or contribution-in-kind reports
actuarial services
internal audit outsourcing services
management functions or human resources
broker or dealer, investment adviser, or investment banking services
legal services and expert services unrelated to the audit
any other service that the Board determines, by regulation, is impermissible.
30
Internal Audit
an independent appraisal function established within an organization to examine and evaluate its activities as a service to the organization.
Different constituencies from external audit
31
Fraud Audit
investigate anomalies and gather evidence of fraud that may lead to criminal conviction.Initiated
When corporate management suspects employee fraud.
Or, boards of directors hire fraud auditors to investigate their own suspected executives
32
The Role of the Audit Committee
A subcommittee of the Board of Directors that has special responsibilities regarding audits.an independent “check and balance” for the internal audit function and liaison with external auditors
Usually three people (outsiders)
SOX requires one to be a “financial expert”
