90% ETA Accuracy Myth: What Visibility Tools Miss

Supply chain visibility vendors have marketed a standardized 90% ETA (estimated time of arrival) accuracy metric for years, repeating the figure across sales presentations, RFP responses, and conference keynotes until it became accepted industry gospel. However, new research based on 25 interviews across shippers, carriers, forwarders, visibility vendors, and finance leaders reveals a critical problem: the industry has never defined what this 90% figure actually measures, meaning the metric itself may be meaningless or misleading. This lack of measurement rigor creates substantial operational risk for enterprises relying on visibility tools for demand planning, inventory management, and customer service commitments.

When ETA accuracy claims lack standardized definitions, companies cannot accurately assess vendor performance, compare competing solutions, or build reliable forecasting models. The consequences ripple across supply chain operations, unreliable ETAs inflate safety stock requirements, worsen customer experience through missed delivery windows, and undermine the entire value proposition of modern visibility platforms. The research highlights a structural accountability gap in the visibility software industry: vendors optimize for marketing claims rather than operational precision.

Supply chain leaders must demand transparent, standardized ETA measurement definitions and audit vendor performance against real operational outcomes rather than accepting industry-standard but unverified accuracy percentages. This shift toward evidence-based vendor evaluation represents a critical evolution in how companies select and measure the technology that underpins modern logistics networks.
