Hamid needs to shift users from using the application from the existing (Old) system to the replacing (new) system.
His manager Lily has suggested he uses an approach in which the newer system is changed over from the older system on a cutoff date and time and the older system is discontinued once the changeover to the new system takes place.
Which of the following changeover approach is suggested by Lily?

In the abrupt changeover approach the newer system is changed over from the older system on a cutoff date and time, and the older system is discontinued once changeover to the new system takes place.
Changeover refers to an approach to shift users from using the application from the existing (old) system to the replacing (new) system.
Changeover to newer system involves four major steps or activities Conversion of files and programs; test running on test bed Installation of new hardware, operating system, application system and the migrated data.
Training employees or user in groups Scheduling operations and test running for go-live or changeover Some of the risk areas related to changeover includes: Asset safeguarding - Data integrity - System effectiveness - Change management challenges - Duplicate or missing records - The following were incorrect answers: Parallel changeover " This technique includes running the old system, then running both the old and new systems in parallel and finally full changing over to the new system after gaining confidence in the working of new system.
Phased Changeover -In this approach the older system is broken into deliverables modules.
Initially, the first module of older system is phased out using the first module of a new system.
Then, the second module of the newer system is phased out, using the second module of the newer system and so forth until reaching the last module.
Pilot changeover " Not a valid changeover type.
Lily's suggestion is an example of the Abrupt changeover approach. In this approach, the old system is discontinued once the changeover to the new system takes place on a specific date and time.
The abrupt changeover approach is also known as the direct changeover or the cut-off approach. It involves the immediate replacement of the old system with the new system. The users stop using the old system and switch to the new system on a specific date and time. This approach is usually quick and straightforward, and it requires minimal resources and time.
However, the abrupt changeover approach is also a high-risk approach as it can result in significant disruption to the organization's operations. If the new system has any problems or issues, the entire organization may face operational difficulties, and it may take time to resolve the issues. Moreover, if the users are not adequately trained on the new system, it can lead to confusion and frustration, further disrupting operations.
In contrast, parallel changeover involves running both the old and new systems simultaneously, while phased changeover and pilot changeover involve implementing the new system gradually, either by phasing it in over time or by introducing it in a small area of the organization to test its effectiveness before rolling it out to the entire organization.
In summary, Lily's suggestion is an example of an abrupt changeover approach, which involves discontinuing the old system and replacing it with the new system on a specific date and time. While this approach is quick and straightforward, it also poses high risks and can result in significant disruption to the organization's operations.
