ABOUT COLLABORATIVE SYSTEMS INTEGRATION

Pioneering Open
Process Automation

Founded by the architects of the Open Process Automation initiative, CSI brings unmatched expertise to industrial automation.

OUR MISSION

Our Mission

CSI exists to accelerate the adoption of open, standards-based process automation. We believe owner-operators deserve control over their automation infrastructure — freedom to choose best-of-breed components, ability to upgrade on their own timeline, and security of standards-based architecture.

We don’t just advise on OPA — we build it. Our team has designed, commissioned, and supported open automation systems in refining, chemicals, power, and pharmaceutical environments.

OUR VALUES
Open Standards First

Every solution is grounded in published, vendor-neutral standards.

Owner-Operator Advocacy

We work for you, not for vendors. Your interests drive every recommendation.

Engineering Rigor

Mission-critical systems demand precision. Decades of field experience in every engagement.
