The supplier ecosystem for Open Process Automation is more mature than the integrator ecosystem.
This is the operational fact about OPA in 2026 that operators most consistently encounter and least often anticipate. Components exist. Conformance works. Standards are stable. What's scarcer is the system integrator capable of assembling those components into a production-grade system with full architectural integrity, managing the multi-vendor coordination that the assembly requires, and supporting the resulting system through its operational lifecycle.
Why the scarcity is structural
Traditional system integration is organized around vendor platforms. Integrators specialize in specific DCS systems, develop deep expertise in their tools and workflows, and earn margins by efficiently delivering projects within those platforms. The skill set is platform-specific. The economics work because the platform contains the complexity.
OPA inverts this. The architecture is no longer contained within a platform; it spans components from multiple suppliers. The integrator's role is no longer coordination of activities within a vendor's scope; it is custodianship of the architecture across the entire system. This requires different expertise, different methodology, and different commercial structures.
What this means for procurement
Integrator selection is more consequential under OPA than under traditional procurement. An integrator with a vendor-aligned approach will produce a system that drifts toward vendor-aligned structures regardless of which components were nominally selected. An integrator with architectural authority will produce a system that maintains its architectural properties across the lifecycle.
The integrator selection effectively determines whether the architectural intent of the procurement is realized.
What to look for: demonstrated execution on multi-vendor OPA projects — not adjacent platform work that's been rebranded. Independence from any single supplier. Internal expertise on conformance validation. Methodology specific to OPA, not traditional methodology with OPA terminology. Willingness to push back against single-supplier pressure during integration.
If your shortlist of OPA integrators is the same as your shortlist of traditional DCS integrators with no adjustments, your shortlist is wrong.
