Industry 4.0 (Industrie 4.0)
Industry 4.0 (Industrie 4.0) is the German-led strategic initiative for next-generation manufacturing, originally launched in 2011 as part of the German high-tech strategy and now adopted as terminology globally. Industry 4.0 envisions cyber-physical production systems where machines, products and people communicate via Internet-of-Things protocols, enabling new degrees of automation, customisation and operational intelligence. For DACH ERP-bearing manufacturers, Industry 4.0 is the conceptual framework for digital-manufacturing investments accumulated over the past decade.
Core principles
Industry 4.0 builds on four foundational principles. (1) Interconnection: machines, devices, sensors and people communicate via IoT protocols. (2) Information transparency: digital models (digital twins) of physical assets provide real-time context for decision-making. (3) Technical assistance: cyber-physical systems augment human capabilities through real-time data, predictive maintenance and remote assistance. (4) Decentralised decisions: embedded systems make autonomous decisions where possible, escalating to humans only when necessary. The combination produces flexible factories capable of mass customisation at near-mass-production efficiency, rapid product changeover and predictive maintenance that reduces unplanned downtime.
RAMI 4.0 reference architecture
The RAMI 4.0 (Reference Architecture Model Industrie 4.0) is the standardised architecture framework defined by ZVEI, BITKOM and VDMA. RAMI 4.0 provides three axes for orchestrating Industry 4.0 deployments. (1) Lifecycle: from product type definition through instance manufacturing to end-of-life. (2) Hierarchy: from field-device level through machine, workstation, production line, factory, enterprise. (3) Architecture layers: asset, integration, communication, information, functional, business. The Asset Administration Shell (AAS) specification provides the technical implementation of RAMI 4.0 concepts, with the IDTA (Industrial Digital Twin Association) driving standardisation of submodel templates per asset category.
Building-block technologies
- OPC UA (see OPC UA) — the dominant industrial communication standard
- Digital twins (see digital twin) — virtual models of physical assets
- Predictive maintenance (see predictive maintenance) — ML-driven failure prediction
- Edge computing — local processing at the machine and factory level
- 5G connectivity — high-bandwidth low-latency wireless for industrial automation
- Augmented reality — worker guidance for complex assembly and maintenance
- Collaborative robots (cobots) — human-machine collaboration on production lines
- Autonomous logistics — AGVs, automated material handling
ERP integration role
ERP plays the strategic-coordination role in Industry 4.0 architectures. The shop floor (machines plus MES) produces high-frequency operational data; the ERP consumes aggregated metrics for business-level planning and reporting. Specific integration patterns. (1) ERP-to-shop-floor planning: production orders flow from ERP to MES with detailed execution context. (2) Shop-floor-to-ERP feedback: production results, scrap rates, OEE metrics flow back for accounting and analytics. (3) Asset performance feedback: predictive-maintenance signals trigger ERP-side maintenance work orders. (4) Energy and sustainability data: machine-level energy consumption feeds CSRD reporting via ERP. The ERP rarely processes raw IoT streams; that is the MES or IoT-platform's job. ERP consumes the structured outcomes.

Frequently Asked Questions
Is Industry 4.0 still a meaningful term in 2026?
Yes in DACH, less so internationally. German industrial associations (VDMA, BITKOM, ZVEI) continue to drive Industry 4.0 standardisation. International conversations have largely shifted to specific technologies (digital twin, predictive maintenance, IoT) rather than the umbrella term. DACH manufacturers benefit from continued Industry 4.0 framing because the standards (RAMI 4.0, AAS, umati) emerged from this initiative.
How much does Industry 4.0 adoption cost?
Highly variable. Pilot projects: 100,000-500,000 EUR. Single-line transformations: 1-5 million EUR. Multi-line factory upgrades: 5-50 million EUR. Greenfield smart factories: 50-500 million EUR. Most DACH mid-market operations approach Industry 4.0 incrementally rather than as big-bang transformation.
Where does Industry 5.0 fit in?
The European Commission introduced Industry 5.0 (2021) emphasising human-centric, sustainable and resilient manufacturing as evolution beyond Industry 4.0's automation focus. The boundary is more positioning than substance — Industry 5.0 principles overlap broadly with Industry 4.0 implementation. The term has had less industrial uptake than Industry 4.0 maintained.
