Senior or Principal Consultants generally span all functional and technical areas of SAP solutions. If SAP has a product or industry focus, there is a Platinum Consultant somewhere who specializes in it.
Platinum Consultants are not limited to providing typical system-based consulting. As SAP customers and the industry have changed over the years, it is not enough to have superior product knowledge. The best consultants must also be change agents who can help customers architect new business solutions, solve problems, and extract more value out of their SAP solution.
The primary qualification for a Platinum Consultant is product expertise. They need to have expert-level knowledge in their area of focus above what one would expect from a Senior Consultant.
