M1S1 Business System Concepts Flashcards
is a systematic process that includes phases such as planning, analysis, design, deployment, and maintenance.
System Development
What are the two major components of System Development?
System Analysis
System Design
This refers to examining a business situation to improve it through better procedures and methods.
System Analysis and Design
Planning a new business system or one to replace or complement an existing system.
System Design
Examining a business situation to improve it through better procedures and methods.
System Analysis
A component of system development that falls under the responsibility of the systems analyst.
System Analysis
any set of components functioning in an interrelated manner for a common cause or objective.
System
orderly grouping of interdependent components linked together according to a plan to achieve a specific objective.
System
signifies an organized relationship among functioning units or components.
System
What are the Three Basic Implications of the study of systems concepts?
- A system must be designed to achieve a predetermined objective
- Interrelationships and interdependence must exist among the components.
- The objectives of the organization as a whole have a higher priority than the objectives of its subsystems.
An orderly grouping of interdependent components linked together to achieve a specific objective.

Five Characteristics of a System
O I I I CO
Organization
Interaction
Interdependence
Integration
Central Objective
It implies structure and order.
Organization
A computer system revolves around input, processing, output, and storage units. Together, they work as one to produce information.
Organization
Refers to the arrangement of components aimed at achieving objectives.
Organization
This means that parts of the organization or computer system depend on one another. They are coordinated and linked together according to a plan
Interdependence
refers to how each component functions with other components of the system.
Interaction
parts of the system work together within the system even though each part performs a unique function.
Integration
refers to the holism of systems.
Integration
In a business system, hierarchical relationships, starting with the president at the top and extending downward to blue-collar workers, represent the _________________.
organizational structure
follows analysis to achieve the central objective of the organization.
Synthesis
is concerned with how a system is tied together more than sharing a physical part or location;
Integration
A product of a successful integration
synergistic effect
Produced a greater total impact than if each component works separately
Integration
The last characteristic of a system can be real or stated, the user must know this for a successful design and conversion.
Central Objective
Elements of a System

What is the primary objective of a system?
A primary objective of a system is to generate an output that holds value for its user.
The elements that enter the system for processing.
Input
Responsible for the actual transformation of input into output.
Processor
Represents the outcomes of processing
Output
operational core of the system
Processor
may wholly or partially modify the input based on output specifications.
Processors
Guides the system as the decision-making subsystem that directs the sequence of activities involving input, processing, and output
Control
regulates how much and what kind of data enters the system to maintain stability based on desired outputs.
Control
Four Types of Feedback
Positive
Negative
Routing
Informational
Measures output against standards and influences system behavior.
Feedback
External context within which the system operates.
Environment
reinforces the performance of the system.
Positive feedback
generally provides the controller with information for action.
Negative feedback
The “suprasystem” within which an organization operates
Environment
often determines how a system must function
Environment
Limits of the system’s influence and its interaction with other systems.
Boundaries and Interface
