Operational Project Architecture Working Group
ICxA’s operationalisation initiative – where standards meet delivery
Introduction
ICxA has published a rigorous, globally applicable commissioning standard set, the governance framework, that the infrastructure and process industries have long needed.
The next step is equally important: showing companies the simplified steps to translate these standards into operational reality in major capital projects. The Operational Project Architecture (OPA) Working Group connects standards to operational excellence. OPA bridges the gap between standard-setting and real-world delivery, creating a structured feedback loop that carries field intelligence from live projects back into the bodies responsible for developing and refining the standards.
Standards are the foundation. Operationalisation is the frontier.
The OPA value loop: standards operationalised, field intelligence returned, framework strengthened.
What OPA Does – Three Functions, One Feedback Loop
Operationalise ICxA standards in the field
OPA collaborates directly with ICxA Operating Partners and industry organisations undertaking major capital projects – with the goal to gather field-level feedback – for translation back into ICxA frameworks, roles, and verification systems – making the standards more robust and actionable where they matter most.
Captures field intelligence systematically
Through Operating Partner Steering Groups embedded in live project delivery, OPA gathers structured feedback on how ICxA standards perform in practice – what works, what requires clarification, and where the standards can be strengthened.
Feeds evidence back into standards development
OPA distils field intelligence into structured submissions to both the Advisory Council and the Technical Committee – giving ICxA’s standard-setting process an empirical, ground-truth evidence base that drives continuous improvement and informs the Body of Knowledge.
Three functions, one continuous loop: Operationalise · Capture · Feed Back.
ICxA Standards Architecture – Where OPA Fits
OPA operates at the third tier of ICxA’s standards architecture:
Level 1 · Governance Standards – The framework for outcome assurance across the asset lifecycle
Level 2 · Execution Standards – The technical how-to across every phase of the commissioning and operational readiness lifecycle
Level 3 · Operationalisation – OPA’s domain – where standards meet live delivery, and field intelligence returns to strengthen the framework – this is how companies and project teams transform ICxA standards into project value
This three-tier structure means ICxA standards are not simply published and adopted – they are tested, observed, and refined through a governed feedback mechanism. OPA is that mechanism.
Why OPA Matters
Major capital projects face a persistent operationalisation gap: commissioning, operational readiness, and outcome assurance standards exist, but the distance between what a standard says and what a live project delivers is rarely governed or closed. OPA exists to systematically close that gap, and with the empirical intelligence that allows ICxA to identify early signals from the field and adapt when the standards require it.
OPA is not an internal review body – it is ICxA’s boots on the ground – the function that ensures the standards reflect the reality of project outcome delivery, not just the intent of governance.
As ICxA’s global footprint continues to expand, OPA scales with it. Each new Operating Partner Steering Group adds a new field intelligence channel, feeding a common evidence base.
OPA Leadership
Founding Chair
James Peter Henry Tuller, CxPM – VP Scandinavia Regional Governance, ICxA Advisory Council Member
OPA Liaison
David Tain – VP LATAM, Caribbean, Mediterranean Regional Governance, Chair ICxA Technical Committee
David brings technical standards expertise directly into OPA’s operationalisation work and carries field intelligence back into the Technical Committee from the inside – ensuring the TC understands what is being observed in live delivery, and that operating partners understand the technical intent of the standards.
Heinz Inabnit – Chair ICxA Standards Advisory Council
Heinz holds a formal ex-officio liaison role within OPA. Strategic intelligence generated through OPA’s field network is submitted to the Advisory Council through this channel. The ex-officio structure preserves OPA’s operational independence while ensuring direct access to the body responsible for strategic standards governance.
The Scandinavian pilot – currently underway in a live Norwegian process industrial project – is the first operationalisation of ICxA’s Outcome Assurance model in the region, and the first live application of the OPA feedback model.
