Cards

Term
Systems Construction
Definition
the development, installation and testing of system components.
Term
systems implementation
Definition
the installation and delivery of the entire system into production.
Term
Unit or program test
Definition
a test performed on an entire program
Term
systems test
Definition
a test performed on an entire system.
Term
systems acceptance test
Definition
a test performed on the final system wherein users conduct verification, validation, and audit test.
Term
audit test
Definition
a test performed to ensure a new system is ready to be placed into operation.
Term
Systems Performance
Definition
The throughput and response time for processing.
Term
Peak workload processing performance
Definition
The ability for a system to perform during peek processing periods.
Term
human engineering test
Definition
Test the ability for users to learn and use the system.
Term
Methods and Procedures test
Definition
Tests to see if methods and procedures have to be modified if they prove to be awkward and inefficient from the end users' standpoint.
Term
Backup and recovery testing
Definition
the testing of backup and recovery procedures. Simulating a data loss disaster.
Term
Abrupt cut-over
Definition
On a specific date (usually a date that coincides with an official business period such as month, quarter or fiscal year), the old system is terminate and the new system is placed into operation. This is a high-risk approach but no transition costs.
Term
Parallel Conversion
Definition
Under this approach, both the old and new systems are operated for some time period. This ensures that all major problems in the new system have been solved before the old system is discarded. The final cut-over may be either abrupt or gradual. This strategy minimizes the risk of major flaws in the new system. High Cost.
Term
Location Conversion
Definition
When the same system will be used in numerous geographic locations, it is usually converted at one location first.
Term
Staged Conversion
Definition
Like location conversion, staged conversion is a variation on the abrupt and parallel conversions. A staged conversion is based on the version concept introduced earlier. Each successive version of the new system is converted as it is developed. Each version may be converted using the abrupt, parallel, or location strategy.
Term
Verification Testing
Definition
Runs the system in a simulated environment using simulated data. (alpha testing).
Term
stubed test
Definition
a test performed on a subset of a program.
Term
Chief programmer teams
Definition
Team consists of a Chief Programmer who takes responsibility for program design strategy, standards, and construction. A backup chief programmer, program librarian, programmers and specialists.
Term
test scripts
Definition
test all possible events and responses
Term
unpopulated
Definition
database structure is implemented but data has not been loaded.
