Question

In data installation whatchageover strategy would you suggest for the new accounting system?explain your answer

Answer 1

In the case of accounting systems, two strategies can be used for system changes which are as follows:

Direct Cutover -:
In simple words direct cutover approach is a direct approach where old system is cut and over write by new system. The direct cutover approach causes the changeover from the old system to the new system to occur immediately when the new system becomes operational. This is a least expensive method among all four but involves high risk of data loss. With the direct cutover method, company cannot revert to the old system as a backup option. Direct cutover involves more risks of total system failure and if there is a system failure in health centre then it will be difficult to store information of child who visits health centre and this will result in improper storage of data. But as there is lack of funds, this approach will be a possible option because of its low cost application among all four approaches.

If the concerned organization have multiple branches, then the following technique is much more suitable.

Pilot Operation -:
The pilot operation changeover method involves implementing the complete new system at a selected location of the company. The group that uses the new system first is called the pilot site. The old system continues to operate for the entire organization including the pilot site. After the system proves successful at the pilot site, it is implemented in the rest of the organization, usually using direct cutover method. Pilot operation is combination of parallel operation and direct cutover methods. Pilot site assure the working of new system and reduces the risk of system failure. This is also less expensive than the parallel operation as only at one section both system works for limited period. This is less expensive and safer approach as its combination of both direct cutover and parallel operation. It will save money of health centre and also keep their data safe with smooth working.
