The systems conversion technique of totally removing the existing system and immediately implementing the new system is called a A. pilot conversion B. crash conversion C. phased conversion D. parallel run E. None of the above

pilot conversion
crash conversion
phased conversion
parallel run E. None of the above

The correct answer is: B. crash conversion.

A crash conversion is a systems conversion technique of totally removing the existing system and immediately implementing the new system. It is also known as a “big bang” conversion. This type of conversion is usually done when there is a need to quickly implement a new system, such as when the existing system is no longer meeting the needs of the organization.

A pilot conversion is a systems conversion technique in which the new system is first implemented in a small part of the organization, such as one department or division. This allows the organization to test the new system and make any necessary changes before it is implemented throughout the organization.

A phased conversion is a systems conversion technique in which the new system is implemented in stages, with each stage being implemented in a different part of the organization. This allows the organization to gradually transition to the new system and minimize disruption to operations.

A parallel run is a systems conversion technique in which the new system is run alongside the existing system for a period of time. This allows the organization to compare the results of the two systems and make any necessary changes before the new system is implemented permanently.

E. None of the above is not a valid answer.
