Open Process Automation: Architecture, Execution, and Transformation

The comprehensive reference work on open process automation — written for the engineers, system integrators, and decision-makers navigating the most significant structural transition in industrial control in a generation.

Open Process Automation: Architecture, Execution, and Transformation

About the Book

Industrial control systems have shaped the modern world quietly and continuously — but the architectures that delivered decades of reliability did so through tight integration, vendor-defined platforms, and long lifecycle lock-in. Open Process Automation is the response: not a new product or a single technology, but a redefinition of how control systems are structured.

This book explains what the O-PAS standard defines, what it does not, and what it takes to move from architectural intent to operating reality. It does not assume traditional systems are flawed — it examines, clearly and practically, how open architecture changes engineering, procurement, operations, and economics across the full system lifecycle.

  • 20 chapters — architecture through transformation
  • Appendices — financial analysis framework, procurement templates, ExxonMobil OPAF case study
  • For — engineers, system integrators, and decision-makers
