Identify the method of system changeover that maintains the old system operational after the new system is launched.

Question

The practice of keeping an old system operational after a new system has been launched is known as:

A. Direct Changeover

B. Parallel Changeover

C. Phased Changeover

D. Pilot Changeover

E. Concurrent Changeover

Answer

B. Parallel Changeover

Explanation: The correct answer is B because Parallel Changeover involves running the old and new systems simultaneously for a period of time. This method allows for comparison and ensures that the new system works correctly before fully phasing out the old system. It minimizes risk by allowing users to revert to the old system if issues arise with the new system.
