In 2025, factories are moving from AI pilots to scaled outcomes. EU AI Act timelines keep governance front-of-mind, while leaders report hard results in quality, throughput and energy use. Focus your roadmap on use cases with measurable ROI, minimal data requirements, and deployment patterns that slot into MES/QMS.
2025 use cases that pay back
Start where ROI shows up on the P&L. Computer-vision QA reduces scrap and rework; “lighthouse” sites report defect cuts up to double-digit and occasionally order-of-magnitude levels within months. Predictive maintenance limits unplanned stops and extends asset life. GenAI copilots grounded in SOPs shorten troubleshooting and onboarding time on the line. Not hype. Documented impact.
- Vision QA: case studies show up to 49% defect reduction in four months after scaling CV across work centers.
- Predictive maintenance: PdM connects sensor data, CMMS and workflows to avoid costly unplanned downtime and trigger parts/logistics automatically.
- Technician copilots: SOP-aware assistants cut MTTR and onboarding time when paired with targeted training.
- Planning/throughput: AI demand and scheduling models lift service levels and productivity at lighthouse sites.
Reality check: if the use case doesn’t move a KPI (scrap, OEE, MTTR), park it. Numbers or nothing.
Data and infrastructure you actually need
Don’t overbuild. For vision QA, you need stable optics, labeled defect images, and edge inference for latency. For PdM, start with vibration/temperature streams plus clean asset hierarchies in CMMS. For copilots, use RAG to ground answers on approved SOPs and work instructions; index documents and control prompts. Keep inference close to the line to cut latency and cloud egress; sync summaries to the lakehouse for fleet analytics.
• Edge inference: reduces latency and bandwidth, keeps sensitive data local.
• RAG playbook: index, chunk, hybrid-search, re-rank, cite sources.
• Data minimisation: collect what the model needs, not everything.
Avoid cargo-cult stacks. Start with the smallest data slice that can prove value, then widen scope as models stabilise and operators trust results.
The latest cohort of Lighthouses has observed an average 53% boost in labour productivity and 26% reduction in conversion costs.

Build vs buy and deployment patterns
Three questions decide it: speed to first impact, fit with MES/QMS, TCO at scale. Leaders “assetise” AI packaging models, connectors, and training, so solutions deploy line-by-line with minimal engineering. Where off-the-shelf matches your images, sensors and takt time, buy; otherwise, build the last-mile layer (data adapters, prompts, UI) and reuse the rest. Integrate with MES/QMS for work instruction updates and non-conformance workflows; without that hook, insights die in dashboards.
- Pattern: edge model + MES connector + operator UI + feedback loop.
- Scale lever: solution libraries and no-/low-code wrappers to replicate use cases fast.
- Decision rule: if customization exceeds reuse, re-scope or switch vendor.
No shiny PoCs. Shipable assets, versioned and supportable, or don’t start.
Governance, risk and change management
Compliance isn’t a sidebar. The EU AI Act schedule is locked; plan for inventorying AI systems, documenting data, and proving human oversight, especially for higher-risk applications. Use the NIST AI RMF to structure risk controls (map, measure, manage, govern) and align with your QMS. Train operators on failure modes and escalation paths; build a model-validation SOP (hold-out sets, drift checks, rollback). Track decisions and citations for copilots. If you can’t explain a model’s behaviour and updates, you can’t scale it.
- Policy guardrails for data, prompts, and logs.
- RACI: product owner, process engineer, data/MLOps, site champions.
- Change kits: micro-training, job aids, and rollout playbooks.
Governance that slows nothing yet documents everything, that’s the bar.
FAQ
Vision QA, PdM and SOP-grounded copilots—each tied to scrap, MTTR or service KPIs.
Less than you think: stable images for CV, a few sensor channels for PdM, and indexed SOPs for copilots.
