Study Notes
Introduction to System Theory
- System theory analyzes phenomena as a whole, not just the sum of parts.
- Focus is on interactions and relationships between parts.
- Used to understand organization, functioning, and outcomes of an entity.
Definition of System
- A system is a complex combination of resources (people, materials, equipment, hardware, software, facilities, data, information, services).
- These resources work together to fulfill a specific operational requirement.
- Each element directly supports the accomplishment of a given mission scenario.
Definition of System Theory
- A theoretical perspective analyzing a phenomenon as a whole, not just individual elements.
- Emphasis is on the interactions and relationships between parts.
- Aims to understand an entity's organization, functioning, and outcomes.
System Characteristics
- Systems are composed of interconnected components working towards a shared goal.
- Resources include humans, materials, equipment, hardware, software, facilities, and data.
- Many functions often require considerable personnel, equipment, and data resources.
- Effective implementation requires carefully integrating resources.
- Systems exist within a hierarchy; performance is influenced by higher-level systems.
System Characteristics (cont.)
- A system can be broken down into subsystems and related components.
- Interactions among components are crucial for effective design.
- Analyzing components separately is insufficient for effective design; system should be viewed as a whole.
- Interrelationships between components must be understood.
- Systems have a purpose to serve identified needs or objectives.
- Overall objective needs to be achieved in a cost-effective manner.
System Classification
- Systems can be classified as physical, conceptual, natural, human-made, closed-loop, open-loop, static, and dynamic systems.
- Physical systems consist of real components occupying space.
- Conceptual systems are ideas, specifications, and plans for organization.
- Natural systems arise from natural processes.
- Human-made systems are developed by humans.
System Classifications (cont.)
- Closed-loop systems are relatively self-contained, not interacting significantly with the environment.
- Open-loop systems interact with their environments.
- Static systems have unchanging structure and responses depend solely on current input.
- Dynamic systems have varying structure involving components and outputs influenced by past/future inputs.
Understanding Information Systems
- Information Technology (IT) encompasses hardware and software used by firms.
- An information system is a collection of interdependent components for collecting, processing, storing, and distributing information.
- Supports decision making and control in organizations.
Information System (cont.)
- Activities include input, processing, and output.
- Input involves collecting raw data.
- Processing transforms raw data.
- Output is the result of processing, providing useful information for decision making.
Functions of Information Systems
- Systems contain organization and environmental information (e.g., competitors, customers, suppliers).
- Input: Raw data from internal and external environments.
- Processing: Transforming data into useful information.
- Output: Distributing processed information for decision-making and control.
- Feedback: Information returned for subsequent action.
