~ His analysis and report generation was excellent and provided valuable insightinto the manufacturing processes. It involved complex statistical analysis andwas done in the time frame planned for and met all project goals. His later work

CORNING in the factory involved data collection and analysis of ongoing production.Discovering Beyond Imogination

John is a dedicated Engineer with a strong work ethic and discipline. His leavingCorning was due to the downturn in our business.

Sincerely,

Gordon Jo s, PECOE Manager, Manufacturing Process EngineeringCorning Incorporated
