Industrial sites use products from hundreds of Equipment OEMs. If each had a proprietary copilot, sites would face massive security validation efforts, and workers would need to manage learning different copilot tools. 

The OCA standardizes how Equipment OEM Copilots are published and subscribed to. Workers access all copilots through one app, while sites manage subscriptions with a single account. 

Expertise flows down, while analytics and feedback flow up, enabling seamless integration across many OEMs and suppliers.
