93% of Manufacturers Own MES, Only 23% Fully Integrate It

The deployment-integration divide

Nearly every large manufacturer has purchased a manufacturing execution system. The vast majority have failed to make it work across their enterprise. A Rockwell Automation report released in July 2026 surveyed 1,560 manufacturing and industrial operations decision-makers across 17 countries and found that while 93% have deployed MES technology, only 23% have achieved full integration.

That 70-percentage-point gap represents a fundamental challenge that has nothing to do with whether the software functions. The problem is organizational: manufacturers are paying for enterprise platforms but operating them as isolated, plant-level tools.

Why it matters

This integration shortfall directly undermines the business case for MES investments. Without bidirectional data flows connecting production floors to ERP, supply chain planning, and quality systems across multiple sites, manufacturers lose real-time visibility, rely on manual reconciliation, and cannot respond quickly when demand shifts or exceptions occur. The gap costs money in operational delays and prevents the coordinated decision-making that justified the original purchase.

What full integration actually requires

Deploying MES at a single plant can track production orders, manage quality records, and report overall equipment effectiveness for that location. Full enterprise integration means something fundamentally different: production, quality, and inventory data flowing in both directions between MES and corporate systems across all facilities, enabling centralized visibility and coordinated planning.

Reaching that level requires clean data models, aligned governance between IT and operational technology teams, and sustained organizational commitment. None of those elements ship with the software license. Many manufacturers deployed MES solutions site by site over years, often with different vendors or versions, making a unified enterprise layer difficult to retrofit later. Others implemented systems primarily to satisfy regulatory or audit requirements, where plant-level functionality was sufficient and the business case for deeper integration was never fully developed.

The operational cost of partial deployment

For operations and IT leaders evaluating their current technology stack, the Rockwell Automation data establishes a clear peer benchmark. If an MES is not feeding real-time production, quality, and inventory data into ERP and supply chain planning systems, it is functioning well below its designed value. That shortfall appears as delayed exception responses, manual data reconciliation between systems, and an inability to model cross-site capacity when demand changes.

The report's scope—17 countries and more than 1,500 respondents—makes it a credible industry benchmark rather than a vendor-specific result. Operations leaders can use the 23% figure as a direct measure against their own integration maturity.

Next steps for manufacturing leaders

Organizations should audit current MES data flows to determine whether their systems feed ERP, quality, and supply chain platforms in real time or if production data still requires manual export and reconciliation. The 23% benchmark serves as an internal scorecard: either the organization has solved this problem or it belongs to the large majority with more work ahead.

When evaluating integration architecture before selecting or renewing MES contracts, procurement teams should ask vendors specifically about bidirectional ERP and supply chain connectivity across multi-site deployments, not just single-plant functionality. The integration gap is rarely a software limitation—it is most often an organizational one, requiring clear ownership of data standards and system interfaces across both IT and OT domains.

The findings were first reported by Rockwell Automation in their "Scaling MES Across the Enterprise" report and highlighted by IndustryWeek editors as a standout development in manufacturing technology.
