In a parallel conversion strategy, the new system:
a. and the old system are run together for a period of time.
b. replaces the old system at an appointed time.
c. is introduced only to a limited area first.
d. is slowly converted from the old system.
e. is tested by an outsourced company.
The correct answer and explanation is :
The correct answer is a. and the old system are run together for a period of time.
Explanation:
In a parallel conversion strategy, both the old system and the new system run concurrently for a period of time. This allows users to operate both systems simultaneously while ensuring that the new system functions properly. The idea is to allow for a smooth transition from the old system to the new system, with a safety net. By running both systems side by side, any issues or problems in the new system can be detected and addressed before fully switching over.
The primary advantages of a parallel conversion strategy are:
- Reduced Risk: The major benefit is the safety it provides. If the new system fails or encounters issues, the old system is still operational, so there’s no disruption to the business. This makes it one of the safest methods of system conversion.
- Immediate fallback: If users experience problems with the new system, they can quickly revert to using the old system without significant disruption.
- Increased Costs and Resources: Running both systems in parallel can be costly and resource-intensive, as it requires more infrastructure and personnel to support both systems. This might not always be feasible, especially for large-scale organizations.
- Time-Consuming: The parallel approach also takes more time. Businesses may need to continue using both systems for weeks or months, depending on the complexity of the new system.
