The industrial automation industry has made substantial progress over the past two decades. Inside manufacturing facilities and warehouses, automation penetration is high, the technology is mature, and the return on investment is well understood. Most large-scale manufacturers are not debating whether to automate their production lines or storage systems. Those decisions have already been made.
What has not been resolved is what happens between buildings.
This article benchmarks automation maturity across the full logistics stack, identifies where the gap exists, and explains why closing it is no longer a future consideration.
The current state of indoor automation
| Function | Automation level | Common technologies |
| Raw material infeed | 70–90% | Conveyors, AGVs, scanners |
| Production line movement | 80–95% | AMRs, AGVs, conveyors |
| Palletising and packing | 95–100% | Robotic palletisers |
| Internal warehouse handling | 60–90% | AMRs, AS/RS |
| Storage and retrieval | 90–100% | AutoStore, SSI Schäfer |
| Inbound / outbound scanning | 80–95% | Cognex, Honeywell |
The picture is consistent: most large manufacturers already operate individual buildings as highly automated environments. The indoor automation problem, for these companies, is largely solved.
What automation looks like between buildings
| Function | Automation level | Reality |
| Outdoor pallet transport between buildings | <5% | Forklifts and tuggers dominate |
| Weather-exposed logistics | ~0% | Rare custom pilots only |
| Yard-to-warehouse transfer | 5–10% | Predominantly human-operated |
| Factory-to-warehouse transport | ~0% | No standard automated solution exists |
The contrast with indoor automation is stark. A facility running palletizers at 98 percent, AS/RS at 95 percent, and AMRs across its production floor is likely still moving pallets between buildings with forklifts on rotating shifts. The indoor and outdoor automation environments are not connected. They are separated by a manual process that operates on a fundamentally different logic from everything else on the site.
This is the automation gap.
Why the gap is a structural problem, not an operational one
The persistence of the automation gap is sometimes attributed to technical difficulty or cost. Neither is the complete explanation.
The actual cause is a category boundary. Every major automation vendor designs products for indoor environments. Conveyors, AMRs, AGVs, and AS/RS systems are built for controlled floors, defined pathways, and protected spaces. They stop at the building exit by design — the outdoor environment introduces weather, variable terrain, road crossings, and mixed-traffic conditions that indoor automation is explicitly not engineered for.
On the outdoor side, forklifts and yard equipment have historically been the de facto transport system. Flexible and familiar, but expensive to operate, dependent on labor, and disconnected from the data and scheduling systems that govern indoor automation.
The gap between these two categories has never been filled by a standardized commercial product. Most industrial sites have invested substantially in indoor automation while continuing to operate their outdoor logistics exactly as they did before any of that automation existed.
The four-layer model
End-to-end automation on an industrial site — what the industry calls automated source-to-sink pallet transport — requires four layers to operate without interruption.
| Layer 1 | Inside-building automation. 80–95% penetration. Largely solved. |
| Layer 2 | Loading and unloading dock integration. Partially addressed on modern sites. |
| Layer 3 | Between-building transport. <5% penetration. This is the automation gap. |
| Layer 4 | Receiving dock integration at the destination building. Partially addressed, dependent on Layer 3. |
The consequence of a missing Layer 3: Layers 1, 2, and 4 cannot deliver their full designed performance. Indoor automation is only as effective as the flow it is connected to. When the handover between buildings is manual, variable, and unpredictable, the efficiency gains from everything else on the site are capped by that constraint. This is why throughput improvements on automated lines frequently plateau — the machine is not the bottleneck. The gap between buildings is.
Quantified impact of the gap
Labor cost
A single cross-building route with three-shift coverage typically requires four to five operators. Annual labor cost per route: €180,000 to €275,000.
Throughput impact
Forklift-based transport does not operate at a consistent cycle time. Variability of 30 to 50 percent above the theoretical minimum is common. This variability propagates into indoor systems: palletizers buffer output, AS/RS inbound queues extend, AMR missions are rescheduled. Sites that have measured the correlation between outdoor transport timing and indoor output consistently find that 1 to 3 percent of total production capacity is lost to outdoor transport inconsistency alone. For a site generating €50 million annually, that is €500,000 to €1.5 million in unrealized output per year — not from equipment failure, but from a forklift route that nobody assigned to a KPI.
Safety exposure
Outdoor forklift operations in mixed-traffic environments are the primary vehicle-related incident risk on most industrial campuses. EU-level data consistently identifies forklifts as the primary source of fatal and serious injuries in industrial logistics outdoor environments.
Asset underperformance
An AS/RS or palletizer running below its rated capacity because outdoor flow is inconsistent represents a real return-on-investment shortfall on systems already installed and paid for. Closing the outdoor gap directly improves the utilization of those assets.
The competitive landscape against the four-layer model
Mapping the competitive landscape against the four-layer model produces a clear picture of where each category sits and where the gap remains.
Indoor automation vendors operate entirely within Layer 1. Well-matched to that layer. Cannot address Layer 3 by design.
Forklift and yard equipment manufacturers serve as the de facto Layer 3 operators on most sites. Flexible, but at a cost and operational profile incompatible with the predictability requirements of modern automated production.
Custom outdoor automation projects — large outdoor AGVs, underground tunnel installations — have been commissioned by individual large industrial facilities. Engineering-intensive, capital-heavy, site-specific, and not a scalable commercial category. Inaccessible to mid-sized industrial sites where the economics of the gap are equally compelling.
The gap in the competitive landscape is precise: no standardized, commercial, pallet-level, cross-building automation category exists at scale. Every company currently handling outdoor pallet transport between buildings is using equipment that was not designed for that purpose — at a cost and performance level that the rest of their automation stack cannot compensate for.
What closing the gap delivers
| Dimension | Impact | Data basis |
| Labor cost | 30–60% reduction on automated routes | ~ ecoro estimate; direction consistent with AGV ROI research [2] |
| Safety | Immediate elimination of forklift-pedestrian conflict on the route | Physical outcome, not modeled |
| Throughput | 10–25% improvement on connected indoor assets | ~ ecoro deployment data; named customer case is stronger evidence |
| ROI payback | 1.4–2 years on qualifying 3-shift deployments | ✓ AGV Network [2]; ecoro reference case [~] |
| Scalability | Additional routes via configuration, not additional headcount | System architecture — no external citation required |
The business case for closing the automation gap is driven by factors that are all moving in the same direction at the same time. Labor availability for forklift operators is declining. Safety regulations around outdoor forklift operation are tightening. Sustainability commitments are creating pressure to eliminate fossil fuel-powered outdoor logistics. Indoor automation investments are returning less than their potential because they are connected to an unautomated outdoor layer.
Companies that benchmark their automation stack against the four-layer model — rather than against their indoor performance alone — consistently identify between-building transport as the highest-impact, lowest-automation area remaining in their operations.
