Introduction: Smart Manufacturing Is at an Inflection Point
For more than a decade, Smart Manufacturing initiatives have been driven by systems. ERP, MES, PLM, IIoT platforms, analytics stacks, and now AI have dominated transformation roadmaps.
Yet across industries and geographies, in many current implementations, a consistent pattern has emerged:
This is no longer purely a technology gap.
It is increasingly a standards and data-governance gap.
Manufacturers have successfully connected systems—but often struggle to scale meaning, trust, and reuse across operations.
Smart Manufacturing is now entering a new phase, where how data is defined, governed, and consumed matters more than which system produces it.
For manufacturing operations specifically, this shift affects:
- Production execution consistency
- KPI reliability (including OEE alignment)
- Quality traceability
- Cross-plant performance benchmarking
This marks a structural shift in how digital manufacturing ecosystems must be designed.
Why the Current Approach Is Reaching Its Limits
Traditional manufacturing digitalization has relied heavily on:
- Platform-centric data models
- Custom point-to-point integrations
- Project-specific interpretations of data meaning
- Inconsistent OEE calculations across sites, due to varying definitions of Availability, Performance, and Quality (misalignment with ISO 22400)
- Digital Twins stagnating after commissioning, as-built and as-maintained data lack governed semantic continuity
- AI models failing to scale across plants, because contextual definitions differ
- Genealogy breaks impacting compliance and recall management
- Data is consumed, not copied
- Access is governed, not hard-coded
- Meaning is standardized, not inferred
- KPI reinterpretation across plants
- Quality context loss between MES and QMS
- Supplier-to-OEM genealogy discontinuities
- Manual reconciliation during audits
- Suppliers, OEMs, operators, and service partners collaborate without duplicating data
- Intellectual property remains protected
- Ownership and control are preserved across organizational boundaries
- Architectural rather than contractual
- Embedded rather than renegotiated
- Governed rather than improvised
- Production Operations Management
- Quality Operations Management
- Maintenance Operations Management
- Inventory Operations Management
- As-designed
- As-ordered
- As-built
- As-delivered
- As-maintained
- Consistent OEE benchmarking across lifecycle stages
- Traceable genealogy across supplier and production events
- Preserved quality context from design through field service
- Audit-ready regulatory compliance
- Living Digital Twins
- Scalable AI in production
- Predictive and prescriptive operations
- Regulatory traceability
- Limited widely adopted end-to-end data standards
- Lack of enterprise-wide canonical operational data models
- Vendor optimization for platform integration rather than interoperability
- Data semantics defined per project rather than per lifecycle
- AI scales experiments, not stable production outcomes
- Digital Twins inform monitoring, not closed-loop decisions
- OEE comparisons lack consistent definitions across plants
- Genealogy and compliance reporting require manual reconciliation
- Ecosystem collaboration remains fragile
- The largest platform
- The most features
- The fastest deployment
- Standardize operational data meaning
- Align KPI definitions across sites
- Govern data usage across lifecycle and partners
- Enable ecosystem-level interoperability
- From systems to standards
- From integration to interoperability
- From projects to ecosystems
