WEEK 9 While using this system change over in the student record system & course selection system is that the new information system is implemented while terminating the old system which is giving a lot of trouble to the administration as well as the student also to knew about them.¨ IN this direct cut over system student and the administration is existing it on full of risk because if the new system is failed to work and they don’t have the old system also where they can store the data of the student. On the other hand it is not expensive and the process can be implemented at one time only. Some time while implementing this method some time administration can use this method also.¨ In this parallel operation change over method the administration can check the record of the student also on both the ways with the help of new system as well as the old system also in this there is lower risk also because if one system fail to work the other system is there to have a look on the student record as well as course selection system .¨ In this pilot operation system the old system is terminated and the whole system is work on this new system only .But some time during pilot operation the old system continue to operate for the administration.¨ In this Phased operation method allows the administration & the student for the changes in stages or in modules& there is risk of errors or failures is limited to implement in modules only& it is less expensive also. In this student administration has there work load less and faster also to access the student record & the course selected for the student is done faster.
