A) parallel conversion
B) phased-in-phased-out conversion
C) plunge conversion
D) pilot conversion

Accepted Answer

This method is called phased-in-phased-out conversion, where modules of the new system are implemented gradually while the corresponding parts of the old system are retired in phases. This helps reduce the risk and impact of potential errors or issues that may arise during the implementation process.

Question 5

With the _____ approach, an organization chooses an outsourcing company in any part of the world, as long as it can provide the needed services.
A) onshore outsourcing
B) nearshore outsourcing
C) offshore outsourcing
D) inshore outsourcing

D) pilot conversion

Accepted Answer

This is the definition of pilot conversion, where a limited area of the organization is used to test the information system before a full implementation throughout the entire organization.

Question 9

In _____ of the implementation phase of the systems development life cycle (SDLC), an old system is stopped and a new system is implemented.
A) parallel conversion
B) phased-in-phased-out conversion
C) plunge conversion
D) pilot conversion

Accepted Answer

Plunge conversion, also known as direct conversion, involves stopping the old system and implementing the new system all at once. This approach is suitable for small systems or organizations with limited resources and time. However, it is considered risky because any problems with the new system can cause significant disruption to business operations.
