Which conversion method gradually adds volume to the new system while still operating the old system?

The phased conversion method is characterized by gradually introducing the new system in increments while still keeping the old system functional. This approach allows organizations to implement the new system component by component, which can help mitigate risks associated with full-scale deployment. By gradually adding the new system's functionalities, users can adapt over time, and any issues that arise can be addressed without the chaos of a complete system switchover.

This method is particularly beneficial for organizations that want to ensure the stability of processes and data continuity, as it allows for a more controlled integration. It also provides the opportunity for training employees in a phased manner, reducing the burden of learning everything at once. Consequently, if any problems occur, organizations can revert to the original system without significant disruption.

Understanding this method is critical for ensuring effective system implementation and management within the broader scope of Information Systems and Controls.
