What is System Changeover?
System changeover refers to enabling a smooth shift from one way to another way of doing things. Its primary focus is to reduce the hindrances that could be caused due to the changeover. The three forms of changeover practiced among the companies are:
- Phased Implementation: only one part or module of the system will be changed from old to new. Once it is effective, the changes of the other modules follow.
- Parallel Implementation: the new, as well as the old systems, run parallelly until the managers evaluate the efficiency of the new one. Once the new system delivers desired output, the old one will be removed.
- Direct Implementation: it is the immediate change where the new system takes over the old system. It is identified to be the cheapest yet risky system changeover.
