Pico MES is a fresh approach to factory operating systems and enables a connected environment to limitless factory tools, capturing data for visibility into the supply chain. Pico MES has migrated dozens of mid-sized factories off of paper-based systems and helped improve product quality for American factories in battery manufacturing, automotive, and aerospace.
