QoS Metric ___ is the amount of time a system is
not available for processing
QoS Metric ___ is the available storage space,
number of users, number of connections, or
number of packet
Maintenance Phase
The ___ ___ of the SDLC involves day-to-day
operation of the system, making modifications to
improve performance, and correcting problem
User Documentation
___ ___ describes how to interact with the system
to accomplish specific task
Distributed Processing

processing tasks are distributed to servers and
Test Area
A ___ ___ is a place where software testing can
occur without disrupting the organization's regular
information system
QoS Metric ___ is the amount of data processed
in a particular time interval
User Levels
QoS Metric ___ ___ is the number of users at
peak, average, and low times
QoS Metric ___ is the number of errors occurring
in a particular time interval for a particular function
Application Testing
___ ___ is the process of trying out various
sequences of input values and checking the results
to verify that the application works correctly
Request for Proposal
A ___ ___ ___ (RFP) is a document that describes
the information system problem and the
requirements for the solution
Unit Testing
As each application module is completed, it
undergoes ___ ___ to ensure that it operates
reliably and correctly
System Testing
After unit and integration testing are completed,
___ ___ ensures that all hardware and software
components work together correctly

located computer
Integration Testing
When all modules have been completed and
tested, ___ ___ is performed to ensure that the
modules operate together correctly
Pilot Conversion
___ ___ works well in organizations with several
branches that have independent information
processing systems because the new information
system is activated at one branch at a time
Response Time
