Midterms Exam Reviewer M1S1 Flashcards
is a systematic process that includes phases such as planning, Analysis, Design, Deployment and Maintenance.
System Development
Major Components of System Development:
- System Analysis
- System Design
Refers to the process of examining Business Situation with the intent of improving it with better procedure and methods
System Development
is the process of planning a new business system or one to replace or complement an existing system.
System Design
Gathering and interpreting facts, diagnosing problems and using the information to recommend improvements to the system.
System Analysis
may be referred to as any set of components which function in an interrelated manner for a common cause or objective.
System
System is Derived from the Greek Word “______”
Systema
this means an organized relationship among functioning units or components.
Systema
is an orderly grouping of interdependent components linked together according to a plan to achieve a specific objective.
System
Characteristics of a system:
- Organization
- Interdependence
- Central objective
- Interaction
- Integration
It implies structure and order
Organization
it is the arrangement of components that helps to achieve objectives.
Organization
refers to the manner in which each component functions with other components
Interaction
this means that part of the organization or computer system depend on one another. they are coordinated and linked together according to plan
interdependence
refers to the holism of system. synthesis follows analysis to achieve central objectives of the organization. “__________” is concerned how a system is tied together.
Integration
it means that parts of the system work together within the system even though each part performs a unique function. successful “_____________” will typically produce synergistic effect and greater total impact than if each component works separately;
Integration
the last characteristic of a system is its “_______________”
Central Objective
“______________” may be real or stated. although a stated “_____________” may be the real “_____________”, it is not uncommon for an organization to state one objective and operate to achieve another.
Objective
user must know the “__________________” of a computer application early in the analysis for a successful design and conversion
Central Objectives
Elements of a System:
Input -> Processor (Control) -> Output -> Feedback
Boundaries and interfaces (Output)
Environment
a major objective of a system is to produce an “_______” that has value to its user.
Output
are the elements (Materials, Human Resources and information) that enters the system for processing
Input
is the outcome of processing
Output
is the element of a system that involves the actual transformation of input into output.
Processor
It is the operational component of a system.
Processor
“___________” may modify the input totally or partially, depending on the specification of the output.
Processor
as the output specification change so does the “___________”. in some cases, input is also modified to enable the “______________” to handle the transformation.
Processor
element that guides the system. it is the decision - making subsystem that “__________” the pattern of activities governing input, processing and output
Control
Control in a dynamic system is achieve by “______________”
Feedback
Measures output against a standard in some form of cybernetic procedure that includes communication and control.
Feedback
may be positive or negative, routing or informational.
Feedback
reinforces the performance of the system.
Positive Feedback
generally provides the controller with information for action.
Negative Feedback
is the “suprasystem” within which an organization operates. it is the source of external elements that impinge on the system
Environment
