The four possible approaches that help CCPS in system change over are:
Direct Cutover: The implementation of direct cut over causes immediate change of the existing system to the new system. In Capricornia Car Pool System, clerk manages all the processes like booking, vehicle fleet maintenance and reporting. In the new system that automatically generates daily reports, vehicle logistics and vehicle tracking, it could be difficult for the clerk to manage changes, detect errors. Besides this, in direct cut over implementation, if the system has totally failed there would be no way that you can get back to the old system, also, clerk may perform mistakes in the process of getting used to the new system and he may require some training to work with it. So, it is not possible to implement direct cut over in enhancing the performance of the system.
Parallel Operation: The use of parallel operation method in implementing the new system is recommended to some extent. In this process of using both the systems simultaneously, some of the problems mentioned in direct cut over can be conquered. The outputs of both the systems can be compared, helping the employee in finding errors in the new system. Parallel operation method provides time for the employees to get used to the new system (training) and expertise in it. Hence if the clerk or other staff find errors in booking a vehicle or generating invoice, they could easily identify and manage the situation. Parallel operation method has some disadvantages as well. It increases the cost of implementing the system and also increases workload on the employees, as they have to observe and work with both the systems, thereby decreasing the work speed.
Pilot Operation: This operation includes both the operations of direct cutover and parallel operation. The difference is that it operates in parallel in a particular branch or in particular department and depending on its success value direct cutover occurs in the rest of the branches. So implementing and testing both new and old system in one of the branches of CQU and depending on its success value and expertise of employees it can be implemented in other areas too. Therefore, pilot operation overcomes the factor cost of operation and thereby it overcomes all the anomalies of direct cut over and parallel operations.
Phased Operation: As the name itself says, Phased operation is performed in phases, say, departments in a factory, or other sub systems and then finally to the whole system. These changes in phases or sub systems may occur using any of the three changeover methods. In CCPS, the first change may occur in reservation phase and then move on to the other sub systems. If the reservation and logistic systems succeed in performing its operations, it would support the success of invoice system too. Advantages of the system include minimization of errors and thereby failures, efficient maintenance of the new system and so on.
