The most significant challenges were the need for a quick ramp up and replacing a bigger team with a well qualified team. Wipro handled all the challenges in a phased manner and successfully took over the engineering ownership of the product:

	Wipro engineers underwent introductory training on the product for 2 weeks at the customer site. After the initial training, Wipro engineers underwent on the job training and started fixing bugs with guidance from client engineers. This secondary ownership phase lasted about 2 months. From the third month, Wipro took complete engineering ownership and started migrating work offshore. This was well ahead of the client’s expectation of migrating engineering ownership to Wipro offshore.
	A six member team of Wipro engineers transitioned the engineering responsibility from an existing team of ten engineers, with one onsite coordinator and the rest located at offshore.
	Towards the end of secondary ownership phase, Wipro set up an offshore lab with VPN connectivity to the client site. The offshore lab was fully functional within a week of equipment arrival. This helped in a seamless migration of work offshore.
	Wipro engineers provided quality fixes in the areas of core OS running as a layer over VxWorks, HTFS, snapcopy, NFS, CIFS, FTP, networking, RAID, SCSI and FC.
	The average outstanding problem reports used to be 18-20 bugs. After Wipro taking over the sustenance engineering responsibility, the average has come down to 2-4 bugs. This clearly indicates the improvement in product stability.
