Our customer is a global telecommunications giant

Keeping the changing market scenario in mind, the customer took a business decision to discontinue its B-RAS product. However the existing B-RAS customers had to be supported.

The customer chose Wipro for the complete maintenance ownership of the product. The challenge was to provide global support at a low cost, without compromising on the quality and to do the transition in just 3 months time without affecting the already planned release schedules to the end customer.

During the initial onsite phase of 3 months the project management team interfaced with the Customer managers and captured the priorities. A detailed project execution plan was prepared. The project team underwent general training that included build procedures, debugging tools and test tools. Individual team members underwent trainings related to the modules of their responsibility.

Parallely the lab/network management team prepared the lab resource procurement and shipment plan. The lab and the development and test environment setup was completed in two weeks at Wipro Bangalore. During this time, the onsite team completed the maintenance release of the B-RAS software. After the release the onsite to offshore transition was completed and steady state maintenance activities started.

As of today a small Wipro team working from Bangalore, India handles support activity by providing solutions and software maintenance releases to customers around the world, from Korea and Australia in the Asia Pacific through UK and Saudi in EMEA to the Americas.
