Abstract
As the cost for system maintenance is only increasing, the savings on the system maintenance cost is one of the important task that needs to be continuously worked through I would like to suggest the offshore of maintenance as a solution for the cost savings. Maintenance of the application requires high level operations, knowledge, and in addition to these, prompt and accurate action and quality is also required. To maintain the service level after transferring offshore, it is essential to succeed in KT: Knowledge Transfer. In this article, I will explain the methodology how to lead the application maintenance transfer to off-shore successfully.
