Information Knowledge Wisdom)
Data in DIKW - <<<ANSWER>>>The input directly received
by the user (or computer). It is generally not usable until it has

,Information in DIKW - <<<ANSWER>>>Having been inferred
from data; one or more processes have been applied to the data

having both knowledge and experience.
Maintenance - <<<ANSWER>>>Modifications or corrections
to the system are made
Alpha Testing - <<<ANSWER>>>System developers assist end
users as they interact with new system; simulated data is used

2. Final Documentation
3. End User Training
Direct Conversion - <<<ANSWER>>>Old system is turned off
and the new system is turned on at a specific data and time
Parallel Conversion - <<<ANSWER>>>There is a period of
time in which both systems are operating concurrently
Pilot Conversion - <<<ANSWER>>>Involves starting the
conversation with a portion of end users
Phased Conversion - <<<ANSWER>>>Deploys a subset of the
system first, rather than deploying the whole system at once
Business Continuity - <<<ANSWER>>>The activity performed
by an organization to ensure that critical business functions will
