Direct Cutover
Through this approach Capriconia Car Pool System cut over the existing manual system to new system.
Benefits:
- There is less possibility of total system failure so it’s less risk oriented.
- Timing is imporortant factor of each system, if any cyclic information related to time is given to the Capriconia Car Pool System then it can only converted through the cutover method.
Limitations:
- It is not risk free. If total system fails then whole information may lost.
- Without testing it may cause the errors. In new Capriconia Car Pool System if we insert
The wrong information then it may cause the errors. E.g.: while giving input to the system if we give the wrong staff member’s name then it will cause the problem.
3. Detecting minor error is also a problem. In new Capriconia Car Pool System when we will
Enter the huge data then it is quite difficult to find the minor errors.
Parellel Operation:
Banefits:
- It has backup of old system. If the new Capriconia Car Pool System doesn’t gives the require out put we have the old system.
- We can compare the result of new Capriconia Car Pool System with the old system either it is correct or not.
Limitations
1.costly
2. Both system must to do same task.
Pilot Operation:
Banefits:
- Less expensive: when we implement the new system in part of organization instead of the whole organization
- Reliable and reduce the system failure : if it works in part of system then it will work successfully in whole organization.
Phased Operation:
Banefits:
- When we enter the new system into the subsystem of the existing system then there is less possibility of errors. For eg. While implement the whole system if implement the new automatic system in the part of Capriconia Car Pool System then there will be less possibility of errors.
- It is less expensive than the implanting the whole system at once.
Limitations:
- If we can not divide the Capriconia Car Pool System into modules then it can not be implanted.
