Study Notes

What is a System?

A system is a set of elements or components that work together to achieve a goal.
Systems take inputs, transform them, and produce outputs.
They exist within an environment but are separate from it.
Systems are made up of sub-systems.
They use feedback from their environment for control.

Information Systems

An information system is a set of components that collect, process, and disseminate data and information.
They provide a feedback mechanism to meet a specific objective.
Information Systems are often referred to as IS, short for Information Systems or Information Services.
In many companies, IS is the name of the department responsible for computers, networking, and data management.
Other companies may refer to the department as IT (Information Technology) or MIS (Management Information Services).

Schematic Model of an Information System

Input: The activity of gathering and capturing data.
Processing: Converting or transforming data into useful outputs.
Output: Useful information, usually in the form of documents and/or reports.
Feedback: Information that helps to improve the system.

Components of Information Systems

The six key components are:
- Hardware: Devices like monitors, processors, printers, and keyboards that accept, process, show data and information.
- Software: Computer programs and their supporting manuals. They provide machine-readable instructions that direct hardware to produce information.
- Data: Facts used by programs to create useful information.
- Telecommunications/Networks: Electronic transmission of signals for communication. Used to connect computers and equipment locally, nationally, and globally, enabling electronic communication.
- People: The most important element. They manage, run, program, and maintain the system. Examples include IT professionals.
- Procedures: Strategies, policies, methods, and rules for using the information system. They guide people in using the system effectively.

Types of Information Systems

There are four main types:
- Transaction Processing Systems (TPS): Collect, store, modify, and retrieve data transactions for an enterprise. Examples include sales order entry, payroll, and shipping. Ideal for routine, repetitive tasks.
- Management Information Systems (MIS): Use TPS data to create reports that managers can utilize for making routine business decisions. Serve Middle Management.
- Decision Support Systems (DSS): Interactive computer-based systems that help decision makers use various forms of data, knowledge, and models to solve problems.
- Executive Support Systems (ESS): Used by senior management for strategic decision-making. Address non-routine decisions that require judgment and evaluation.

Relationship of Systems

The different types of systems in an organization are interconnected.
TPS are major producers of information needed by other systems, which then generate information for other systems.
It is advantageous to integrate these systems to enable smoother information flow and provide a comprehensive view of organizational performance.

Other classifications of Information Systems

Expert Systems (ES): Knowledge-based systems offering expert advice and acting as expert consultants. Examples include credit application advisors and diagnostic maintenance systems.
Knowledge Management Systems: Support the creation, organization, and dissemination of business knowledge within an enterprise. Examples include intranet access to best practices, sales proposal strategies, and customer problem resolution systems.
Strategic Information Systems: Support operations or management processes that provide a firm with strategic products, services, and capabilities for competitive advantage. Examples include online stock trading, shipment tracking, and e-commerce systems.
Functional Business Systems: Support operations and managerial applications of basic business functions. Examples include information systems for accounting, finance, marketing, operations management, and human resource management.

Benefits of Information Systems

Businesses can:
- Quickly, easily, and reliably collect and gather large amounts of data.
- Store and organize large amounts of data.
- Quickly, accurately, and consistently manipulate data.
- Retrieve and communicate information in various useful forms.
- Enforce business rules.

What is Information Management?

IM is the collection and management of information from multiple sources.
The goal is to distribute this information to various audiences.
It aims to capture, store, and deliver the right information to the right people at the right time.
The objective is to help organizations and individuals access and utilize information effectively and efficiently to add value.
IM involves people, policies/processes, technology, and data/information.
