- Scalable for all sizes/industries; 6-18 months typical.
- Involves training, audits, continual improvement.
ISA 95 Details
What It Is
ISA-95 (ANSI/ISA-95, IEC 62264) is an international reference architecture framework for integrating enterprise business systems with manufacturing operations. Its primary purpose is to define models for information exchange between Level 3 (MES/MOM) and Level 4 (ERP) using a hierarchical, activity-based approach based on the Purdue model.
Key Components
- Hierarchical Levels 0-4 defining system boundaries
- Activity models (Part 3) for production, quality, maintenance
- Object models (Parts 2,4) for equipment, materials, personnel
- Transactions and messaging (Parts 5-8) for standardized exchanges
- No formal certification; compliance via architectural alignment
Why Organizations Use It
- Reduces integration risk, cost, errors in IT/OT convergence
- Enables semantic consistency for OEE, traceability, analytics
- Supports Industry 4.0, digital twins, regulatory compliance
- Builds stakeholder trust through shared vocabulary and governance
Implementation Overview
- Phased: assessment, canonical modeling, pilot, rollout
- Applies to manufacturing industries globally; cross-functional teams
- Focuses on governance, data stewardship; no mandatory audits
