Ques. On page 447 the textbook discusses four possible approaches to changing from one information system to another. Post an entry to your blog the explains the implications of using each of these approaches might be used at CQU to change from the existing manual Capricornia Car Pool System (CCPS) to the new system you have been designing in assignments 1 and 2. Your post should include discussion of the benefits and problems associated with each approach
Ans Direct Cut Over:-This change system is the change of current old system to new system swiftly just by stopping the Current system and starting the new system straight away. in the Capricornia Car pool system if we implement the new system just by stopping current legacy system it wont be a feasible option as the cars are always taken by some current staff who actually got it booked through the old system it would be hard updated those details on the new system.
Parallel Operation:- This Change option refers that the old and new information system will operate fully at the same time for a period of time to check the complexities of new system without hampering the old system which is also fully functional. But This kind of change require more manpower to manage. If we follow the same approach in the current Capricornia car pool system we will need more staff member this will increase the management cost for the University. Doesn’t seem to be a feasible option.
Pilot Operation:- This kind of change method involve implementing current system at selected location and then get it tested by the user in that location to find drawbacks and benefits and then implement on all the other locations. This Approach Could be Considered a Ideal option for the implementation for the new Carpool system in Central Queensland University. The Newly designed system could be first implemented in one of the campuses of CQU to be tested and then finally implemented on all the other campuses.
Phased Operation :- This Changeover method allows to implement the new system in stages , or modules. Considering the case of Current Carpool system it wont be a feasible option to implement the new system in module because the old system is totally manual and the new system is total computerized at the same time Capricornia Car pool system is not a complex system with large number of modules but there are fixed modules so it would basically led to more complexities if implemented in phased approach as would increase management cost require more staff to manage two different modules.
