What is System Changeover?
System changeover refers to the process of transitioning from an existing system to a new one while ensuring minimal disruption to an organization’s daily operations. Since multiple systems are often interconnected, careful planning and execution are required to avoid errors during the transition.
Types of System Changeover Methods
Direct Changeover:
The old system is replaced immediately by the new system.
It is the fastest method but carries a high risk if the new system encounters issues.
Suitable for cases where the old system is outdated or unreliable.
Parallel Running:
Both the old and new systems operate simultaneously for a period.
The new system is fully adopted only after proving its efficiency and reliability.
This method is safer but more resource-intensive.
Phased Implementation:
The new system is introduced gradually, replacing the old system in stages.
This approach minimizes disruptions and allows for troubleshooting at each phase.
Ideal for complex system changes that require careful testing and user adaptation.
Choosing the right system changeover method depends on factors like system complexity, risk tolerance, cost, and operational requirements.
