These tools relieve the systems analysts of many repetitive tasks, develop clear documentation, and, for larger projects, coordinate team member activities.
CASE
Another name for system implementation.
conversion
An information system is a collection of hardware, software, people, procedures, and:
data
Prototyping and RAD are alternatives to the systems ___.
life cycle
The last and ongoing phase of the systems life cycle is system ______.
maintenance
Prototyping involves building a prototype or ___.
model
Systems designers evaluate the following types of feasibility: economic, technical, and ___.
operational
What type of feasibility evaluates whether the people within the organization will embrace or resist a new system?
operational
What document shows the levels of management and formal lines of authority?
organization chart
The conversion approach in which the old and new systems are operated side by side until the new one proves to be reliable.
parallel
he approach in which the new system is implemented gradually over a period of time.
phased
System analysis involves suggesting alternative ______.
solutions
Method of analysis in which each component is broken down into smaller and smaller components.
top-down
Systems life cycle phase that studies the present system in depth.
analysis
Diagram that traces data from its origin through processing, storage, and output.
data flow
The type of feasibility that considers the costs of the new system and how long will it take for the new system to pay for itself.
economic
The analysis tool that shows the flow of input data to processing and finally to output is the system:
flowchart
The system analysis tool that shows the relationship between input and output documents.
grid chart
Which systems analysis tool shows the relationship between input and output documents?
grid chart

implementation
Which approach to conversion begins by trying out a new system in only one part of an organization?
pilot
What is the first phase in the systems life cycle?
preliminary investigation
An alternative to the systems life cycle approach using powerful development software, small specialized teams, and highly trained personnel.
RAD
Two alternative approaches to the systems life cycle, that require much less time, are prototyping and:

analysts
The system phase where new hardware and software are acquired, developed, and tested.
development
The four approaches to conversion are parallel, pilot, phased, and ______.
direct
