Which of the following systems implementation approaches should be used if you want to run old system and the new system at the same time for a specified period?
Which of the following systems implementation approaches should be used if you want to run old system and the new system at the same time for a specified period?
The correct option is D Parallel
Parallel systems implementation
approaches should be used if you want to run old system and the new system
at the same time for a specified period.
Parallel running is a strategy
for system implementation where a new system slowly assumes the roles of the
older system while both systems operate simultaneously. This conversion takes
place as the technology of the old system is outdated so a new system is needed
to be installed to replace the old one.
Parallel change over:-
In a parallel changeover, the new
system runs simultaneously with the old for a given period of time. Of all the
techniques, this tends to be the most popular, mainly because it carries the
lowest risk. If something goes wrong at any point, the entire system can be
reverted back to its original state. A primary disadvantage in running two
systems at the same time is higher costs. The parallel changeover process also
can be quite time-consuming.
