Business Drivers

The tax auto-optimization system architecture is relatively mature after years of development. Although system users still raise new requirements, keeping a whole development team in the US is not cost efficient. To optimize resource utilization, the client decided to transfer maintenance and production support work to China and only kept a small group for communication and deployment work. The key objectives of the China project are:

• To implement users’ enhancement requirement
• To monitor system health and find exception
• To fix all the issues in old system
• To be on call for any emergency system issue from front-desk
• To improve system scalability and performance
