The goal of this independent auditing service was to provide businesses and consumers a level of confidence in dealing with new vendors.  In order to be certified, a supplier had to submit a list of all clients they've had over the past to an independent research group based at California State University, San Francisco.  These researchers contacted a large sample of clients to judge customer satisfaction.  Only after completing this rigorous examination (along with requirements for liability insurance, business licenses, etc.) was the company allowed to become certified.  In the most recent survey, Penrose Productions received a 100% satisfaction rating.
