Change over methods:

System change over is helps to get more effective results and smooth running of the process/business. An appropriate system change over is assigned depending upon the structure and organization of the company.In this blog we have to think about system change over in Cornucopia University. Depends on the costs and requirements we should select one of the approaches.

 Approaches are:

1)      Direct cutover: – In this approach the old system is replaced by the new system. It is not preferable method to implement in Cornucopia University because it is a very risky process even though it is very less expensive when compared to other methods. Major errors might abnormally terminate the process and it is even difficult to find out the minor errors because we don’t have the old system.

2)      Parallel operation: – In this approach the new system runs along with the old system. The out put of the new system is compared with the old system and when the management get satisfied with the new system then they will terminate the old system. This is very good method to implement in organizations rather than for small purposes. It is very good to implement in our cornucopia university to reduce the risk of failure but we should not implement this method because it is very expensive to run different types of systems and temporary staff to maintain those systems. So it is not a good idea to put big investment for small processes.

3)      Pilot Operation: – In this aproach a complete system is established and then that system is placed in one of the branches of organization. For that instance a pay roll system is implemented in only one department and this new system is called pilot site. In Cornucopia University it is not possible to implement this method because we have only one department to accomplish all about the student records and course selection system.

4)      Phased operation: – In this approach total system implemented through stage-by-stage/module-by-module basis. If one module runs successfully then we implement to other branches also. In university it is good to implement it to one branch initially and then if it is successful then it is good to spread to other branches as well. It is also very easy to separate the work into modules and then to integrate those modules. Here in this method risk is very low, even though if some errors arise it will effect only that module and the cost is also less when compared to parallel operation.
