ISO 22549-1:2020

Overview

ISO 22549-1:2020 - "Automation systems and integration - Assessment on convergence of informatization and industrialization for industrial enterprises - Part 1: Framework and reference model" defines the basic principles for assessing the convergence of informatization and industrialization (CII) in industrial enterprises. The standard provides an assessment framework, a reference model and component definitions to guide digital transformation efforts that integrate information technology into industrial production.

Key topics and requirements

The standard focuses on structured, repeatable assessment elements rather than prescriptive technical implementations. Key topics include:

• Assessment scope and objectives

  • Assess current CII status, identify weaknesses, and recommend improvements.
  • Input/output architecture for enterprise assessing systems.

• Assessment framework elements

  • Use of evaluation questionnaires, a maturity model, and an assessment reference model to drive assessments and aggregate results.

• Assessment reference model structure

  • Four primary aspects: Infrastructure, Domain application, Comprehensive integration, and Collaborative integration.
  • Infrastructure subcomponents: capital investment, organization & planning, equipment & facilities, information resources, information security.
  • Domain application components: product design, process design, production management, materials management, sales, financial, security, project, maintenance, HR, document, quality, EHS, energy management.
  • Comprehensive integration examples: product-design/manufacturing integration; production management & control integration; production/supply/marketing integration; operation decision support.
  • Collaborative integration: linking functional applications between different enterprises.

• Data and levels

  • Assessment draws on data from functional Level 2 (process control), Level 3 (workflow/production operations) and Level 4 (business activities) per IEC 62264 hierarchy.

• Methodology references

  • Uses object-process methodology notation (ISO/PAS 19450) for graphical modeling and refers to existing assessment terminology (ISO/IEC 33001).

Practical applications

ISO 22549-1:2020 is designed to support:

• Digital transformation planning and benchmarking of CII maturity.
• Gap analysis to prioritize investments in OT/IT, security, and process integration.
• Third‑party assessments by consultants or government bodies evaluating industrial enterprise CII.
• Internal assessments by production, quality, inventory or IT departments preparing roadmaps for integration and automation.

Who should use it

• Industrial enterprise managers, CIOs/CTOs, production and operations managers.
• Systems integrators, industry consultants, auditors and policy-makers focused on manufacturing digitalization.

Related standards

• IEC 62264 (functional hierarchy for manufacturing operations)
• ISO/PAS 19450 (object-process methodology notation)
• ISO/IEC 33001 (assessment process terminology)

ISO 22549-1:2020 helps organizations structure CII assessments, align OT/IT integration efforts, and create actionable roadmaps for improved productivity and resource allocation.
