1.0 What is Business Information Systems?
A business information system is defined as:
Verbatim Definition: "A group of interrelated components that work collectively to carry out input, processing, output, storage and control actions in order to convert data into information."
Purpose and Use:
This information can support the following organizational activities:
Forecasting
Planning
Control
Coordination
Decision Making
Operational Activities
The Business Environment & Business Information Systems
Influences:
All business organizations operate within an environment that affects their operations. An example includes:
Legislation: Controls some of the organization's activities.
Data Collection:
Business information systems collect data from the business environment and convert this data into usable information for effective management.
Components of the Business Environment

Specific environment
Data vs. Information
Definitions:
Data: A collection of nonrandom facts recorded by observation or research.
Information: Data that has been processed/transformed so that it is meaningful.
Process: Business information systems seek to collect business data from the business environment and convert this into business information for managerial use.
2.0 Characteristics of Valuable Business Information
1. Accessible: Information should be easily accessible by authorized users in the right format and at the right time.
2. Accurate: Information should be error-free; inaccuracies can occur due to incorrect data input into the transformation process.
3. Complete: Information must contain all important facts without excess detail.
4. Timely: Information should be provided when needed; e.g., last week's weather conditions may not assist in today's decisions.
5. Economical: Information production should be cost-effective, balancing the value of information with the production cost.
6. Flexible: Information should be adaptable for multiple uses, e.g., inventory data serves various organizational roles.
7. Relevant: Information must be pertinent to decision-makers' requirements.
8. Secure: Protection against unauthorized access is essential.
9. Reliable: Dependability of information is crucial; reliability is influenced by data collection methods and sources.
10. Simple: Simplicity in information is key; complexity can lead to information overload affecting decision-making.
11. Verifiable: Information should be confirmable through multiple sources, ensuring accuracy.
Components of Business Information Systems
Utilization of IT:
Modern organizations use extensive information technology in business information systems, focusing on Computer-based systems.
Key Components:
1. Hardware: Machinery aiding data input, processing, storage, and output.
2. People: Users and personnel managing, running, programming, and maintaining the system.
3. Software: Computer programs governing computer operations, enabling various tasks.
4. Procedures: Strategies, policies, methods, and rules governing the use and maintenance of information systems.
5. Telecommunications, Networks, and the Internet: Includes electronic signal transmission facilitating organizational processes.
6. Databases: Organized collections of related facts and information.
5.0 Types of Business Information Systems
Various types of business information systems include:
1. Transaction Processing Systems (TPS)
2. Customer Relationship Management Systems (CRM)
3. Supply Chain Management Systems (SCM)
4. Executive Support Systems (ESS)
5. Management Information Systems (MIS)
6. Decision Support Systems (DSS)
7. Electronic Business (E-business) systems
8. Enterprise Resource Planning (ERP) systems
9. Knowledge Management Systems
Value Addition of Business Information Systems
1. Improving quality and reduced costs:
Example: Monitoring machinery to notify operators when performance falls outside acceptable limits to maintain quality and reduce waste.
2. Improving efficiency:
Example: Timely information enabling just-in-time manufacturing requires up-to-date data on inventory locations.
3. Sharing knowledge:
Example: CPA firms using information systems for sharing best practices and enabling communication among offices, allowing access to expertise.
4. Improving supply chain efficiency and effectiveness:
Example: Allowing customers direct access to inventories reduces costs and increases customer retention.
5. Improving internal control structure:
An Accounting Information System (AIS) with proper controls defends against fraud and system failures.
6. Improving decision making:
Enhanced decision-making capabilities arise from the use of appropriate information systems.
Detailed Types of Business Information Systems
1. Transaction Processing Systems (TPS):
Defined as an organized collection of components used to record completed business transactions, including:
Revenue system
Purchasing system
HR Management/Payroll system
Production system
General Ledger & Reporting system
2. Customer Relationship Management Systems (CRM):
Designed to manage customer relationships effectively to identify, acquire, and retain customers.
3. Supply Chain Management Systems (SCM):
Aims to manage relationships within the supply chain, including suppliers and distribution networks, focusing on cost-effectiveness and operational efficiency.
4. Executive Support Systems (ESS):
Specialized systems to assist top-level executives in strategic decision making, including hardware, software, data, procedures, and people. Sometimes referred to as Executive Information Systems (EIS).
5. Management Information Systems (MIS):
An organized collection to provide routine information to managers and decision-makers, supporting operational efficiency across various business functions.
6. Decision Support Systems (DSS):
Support problem-specific decision making, focusing on effectiveness rather than efficiency, helping managers to make the right decisions.
