Was just reviewing this Forrester Report available here, Which is a scorecard for Indian SAP Service providers:

Some interesting Excerpts:

Wipro, a tier one Indian vendor, is a strong choice for end-to-end SAP implementations, upgrades, global rollouts, and ongoing maintenance and support. The firm has an extremely strong SAP energy and utilities practice, as well as the strongest telecom experience of any of the Indian vendors. Wipro has done end-to-end implementations for companies such as National Grid and recently delivered a complex end-to-end SAP implementation for SANYO. Although part of the project's complexity was related to SANYO's business processes and supply chain, another part was due to the fact that the implementation was done in Mandarin, Taiwanese, and English.

Forrester evaluated Wipro's current offering and strategy for SAP services against 24 criteria (Attached Figure - Wipro-SAP Service-Evaluation Overview). The firm scored extremely well in all categories, but it was particularly impressive in terms of the number and complexity of global rollouts and implementations, as well as its approach to and investment in SAP centers of excellence (COEs). This means that Wipro is an especially good fit for buyers that:

• Require global rollout skills. Wipro's SANYO implementation is an excellent example of the types of complex and multilingual projects that the company is so good at executing. Customers with similar requirements should consider Wipro as a top choice.
• Are looking for innovation or SAP-sponsored customization. Wipro's investment in its COEs and its relationship with SAP ensures that clients have access to cutting-edge SAP innovation and vertical and/or horizontal customizations.
