Acceptance Test - ANSWER Testing covers the complete information system,including all usual processing scenarios. During an acceptance test, users add
data, including samples of actual or live data, run queries, and generate reports
to imitate actual operational settings. To guarantee that the system works
properly, users and the IT project development team test all processing choices
and outputs. Also known as a system test.
Application Development - ANSWER The process of creating the programs and
code modules that form the foundation of an information system. An application
development group within a traditional IT department consists of systems
analysts and programmers who design, create, and deploy information systems.
Bug tracking software - ANSWER System engineers use defect tracking
software, also known as bug tracking software, to document and track program
defects, code changes, and patches.
Capability Maturity Model (CMM) - Answer SEI developed a model that
incorporates software and systems development into a process improvement
framework.
coding: ANSWER The process of converting program logic into particular
instructions that a computer may execute.
Cohesion - ANSWER A measure of a module's breadth and processing
capabilities. A module that performs a single function or activity has a high
level of coherence, which is desired.

level module that directs lower-level modules known as subordinate modules.
coupling - ANSWER Assesses module linkages and dependency. The reverse of
cohesiveness.
Customer - ANSWER The main user of a system, service, or product.
Data conversion - ANSWER Existing data is loaded into the new system and
altered as necessary. Depending on the system, data conversion might occur
before, during, or after the operating environment has been completed.
Data pair - ANSWER In a structure chart, a data pair represents the data that
one module transmits to another. An arrow with an empty circle symbolizes a
data pair.
ANSWER System engineers use defect tracking software, also known as bug
tracking software, to document and track program faults, code modifications,
and patches.
Design Walkthrough - ANSWER A session with users to assess the interface
with a diverse group of people who will use the new system. This is a
continuation of the modeling and prototyping work that started early in the
systems development process.
