GGI has established partnerships and alliances with industry-leading development firms and factories in the United States, Central America, Europe, Southeast Asia, and China. GGI continues to discover and certify new factories. If GGI's existing factory selection does not have the specific manufacturing skill, GGI will use their network of factory connections to find a new factory that meets the highest standards necessary for a product.

GGI verifies that the quality system requirements conform to the industry needs. High-tech industries often require statistical process control tools including Cpk requirements, trend-charts, data sampling analyses, and sophisticated metrology. GGI’s factory-approval process ensures that factories supporting those industries will have the required capabilities.

GGI is experienced with one-off prototypes, small batches, and management of production manufacturing of over 1-billion parts per year. The quantity ordered will affect the factory cost but not the level of service provided by GGI.
