What characteristic defines a phased changeover?

• A. Both systems are fully operational at the same time
• B. Transition occurs gradually with partial implementation
• C. There is an immediate switch from the old system to the new
• D. Testing is only performed after the new system is adopted

Answer: (B)

A phased changeover is characterized by a gradual transition from an old system to a new system, allowing for partial implementation at each stage. This method is often employed to minimize disruptions and risks, enabling organizations to test new system components incrementally while still operating the old system. This approach allows for adjustments and corrections based on real-time feedback, which can significantly enhance the overall effectiveness and reliability of the transition. For instance, in a phased changeover, different functionalities might be migrated over a set timeline, giving users a chance to adapt to the new system in manageable segments rather than all at once. This reduces the potential for significant operational disruptions and provides opportunities for addressing issues as they arise during the transition. The other methods of changeover present different approaches, such as immediate switches or simultaneous operations, which do not align with the definition of a phased changeover. Therefore, recognizing the significance of gradual implementation is crucial in understanding how a phased changeover operates effectively.
