FINAL EXAM (M1S1) PART 1 Flashcards
is a systematic process that involves Planning, Analysis, Design, Deployment and maintenance
System Development
Two Major Component of System Development:
- System Analysis
- System Design
Refers to the process of examining a business situation with the intention of improving it through better procedures and methods.
System Development
is the process of planning a new business system or one to replace or complement an existing system.
System Design
is the process of gathering and interpreting facts, diagnosing problems, and using the information to recommend improvements to the system.
System Analysis
may be referred as any set of components, which functions in an interrelated manner for a common cause or objective.
System
Greek Word of system?
Systema
an organized relationship among functioning units or components.
Systema
is an orderly grouping of interdependent components linked together according to plan to achieve a specific objective.
System
The study of systems concepts, then, has three basic implications:
- A system must be design to achieve predetermined objectives.
- interrelationship and interdependence must exist among the components
- the objectives of the organization as a whole have a higher priority that the objectives of subsystem
Characteristics of a system:
- Organization
- Independence
- Central Objectives
- interaction
- Integration
it implies structure and order
Organization
refers to the manner in which each components functions with other components of the system
Interaction
it is the arrangement of components that helps achieve the objectives
Organization
it means that parts of the organization or computer system depend on one another.
interdependence.
they are coordinated and linked together according to plan.
Interdependence
refers to the holism of system.
Integration
synthesis follows analysis to achieve the central objectives of the organization.
Integration
is concerned how a system is tied together.
Integration
it means parts of the system works together within the system even though each part performs a unique functions.
Integration
the last characteristic of a system
Central Objectives
Although a stated objective may be the real objective, it is not uncommon for an organization to state one objective and operate to achieve another;
Central Objective
user must know this for a successful design and conversion
Central Objectives
Elements of a system
Input - Process (Control) - Output (Boundaries) - Feedback
Environment
a major objective of a system is to produce an “___________” that has value to its user.
Output
are the elements (material, human resources and information) that enter the system for processing.
input
the outcome of processing
Output
element 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 specifications of the output.
Processor
