William has been assigned a changeover task.
He has to break the older system into deliverable modules.
Initially, the first module of the older system is phased out using the first module of a new system.
Then, the second module of the old system is phased out, using the second module of the newer system and so forth until reaching the last module.
Which of the following changeover system William needs to implement?

A. B. C. D.B.
In phased changeover 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.
Some of the risk areas that may exist in the phased changeover area includes: Resource challenge - Extension of the project life cycle to cover two systems.
Change management for requirements and customizations to maintain ongoing support of the older systems.
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.
Abrupt changeover " 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.
Pilot changeover " Not a valid changeover type.
The changeover task assigned to William involves breaking down the older system into deliverable modules and replacing them with corresponding modules from a newer system. This is a form of changeover strategy that helps to ensure a smooth transition from an old system to a new one.
The four types of changeover strategies are:
A. Parallel Changeover - Both the old and new systems run simultaneously for a period of time, during which data is entered into both systems. Once the new system has been tested and verified, the old system is discontinued, and the new system takes over completely.
B. Phased Changeover - This approach involves gradually implementing the new system in stages. Each phase involves the replacement of a module or part of the old system with the corresponding module from the new system. The process continues until the old system is entirely replaced by the new system.
C. Abrupt Changeover - This approach involves stopping the old system entirely and switching over to the new system immediately. There is no overlap between the two systems, and users must adapt to the new system immediately.
D. Pilot Changeover - This approach involves implementing the new system in a small, controlled environment, such as a single department or location. Once the new system is tested and verified, it is rolled out to the rest of the organization.
Given that William is tasked with phasing out the older system using the corresponding modules of the new system, the correct answer is B - Phased Changeover. In this approach, the system is phased out in stages, and each phase involves the replacement of a module or part of the old system with the corresponding module from the new system.
