Direct changeover: there’s
a single, fixed point where one system stops being used and the new one becomes live
. This is the cheapest, quickest and easiest form of system changeover but is also the riskiest – if the system is broken or inefficient, the whole organisation suffers.

because of the need to operate the two systems at the same time
. It is a great expense in terms of electricity and operation costs. … Parallel running implementation also requires a lot of time and needs frequent maintenance.
What are the four changeover methods?
- Direct cutover.
- Parallel operation.
- Pilot Operation.
- Phased Operation.
What is pilot system implementation?
A pilot implementation is
an activity undertaken in the context of systems development and implementation to test a system in a realistic setting
and thereby learn about the fit between the system and its organizational use situation and about changes necessary prior to full-scale deployment.
What is direct implementation?
With this approach, the system is
implemented and tested to ensure it performs properly
. Then the old system is removed and the new one put in its place without any overlap or limited roll out. The system is not critical to the organisation, so if it has a problem, it will not be too serious. …
