Manufacturers have long relied on layered process audits to maintain quality, safety, and compliance across plant floors. Yet a sweeping new analysis from Ease.io suggests that having an audit program in place and running it effectively are two very different things. The findings expose a persistent gap between audit completion and meaningful execution, one that carries real consequences for manufacturers operating under strict OEM requirements.

Manufacturing Audits at Scale: What the Data Reveals
The Ease.io Layered Process Audit Benchmark Report is the most comprehensive analysis of LPA performance published to date. Drawing from over 2.3 million audits conducted across more than 2,200 manufacturing sites worldwide, the report establishes clear performance benchmarks and highlights where most organizations fall short.
On the surface, the numbers appear encouraging. The average organization completed over 8,700 audits and closed approximately 1,460 findings in the period analyzed. Overall audit completion rates exceed 80% on average. However, when measured against best practice benchmarks, the picture changes significantly.
The On-Time Completion Problem
Completion rates alone do not tell the full story of LPA program health. Fewer than one in three manufacturers meet best practice standards for on-time audit completion, and only 28% of organizations close more than 60% of their audit findings on time.
For automotive and aerospace suppliers, where layered process audits are mandated by most major OEMs, these delays carry significant compliance risk. Falling behind on audit closure timelines is not merely an operational inefficiency; it can directly affect supplier status and regulatory standing.
"Those numbers reinforce what leading manufacturers already know: layered process audits are a powerful lever for operational excellence," says Adam Wegel, CEO. "But what we discovered is that having the right tools is just part of the picture. The real issue is an accountability and execution gap."
Frontline Disengagement: The Zero-Findings Problem
One of the report's most telling findings concerns the quality of audits at different organizational levels. A striking 84% of Layer 1, or frontline, audits result in zero findings. In contrast, upper-level management audits report zero findings only about half the time.
This disparity points to a deeper issue: frontline employees are completing audits without surfacing the issues these audits are designed to detect.
"This shows a clear leadership gap in terms of supporting these critical checks required by industry and customers," says Josh Santo, Senior Director of Industry Strategy & Solutions. "In many cases, that's because people up and down the chain don't truly understand the impact they can make with LPAs, so they treat it like a check-the-box activity."
Leadership Engagement as the Primary Performance Driver
The report identifies leadership participation as the single most influential factor in LPA program maturity. Plants where leaders are consistently involved in the audit process are 20% more likely to complete audits on time across the board.
This finding underscores a broader framework that Ease.io identifies as central to LPA success: People, Process, and Tools. While digital systems clearly play a role, with companies using digital audit platforms showing measurable improvement in completion rates within two years and a reduction in the share of low-performing sites, technology alone is not sufficient.
"All of these findings drive home the fact that the People-Process-Tools framework is the key to success," says Santo. "Engaged leaders are what differentiate top-performing plants from the rest."
Digital Adoption and the Path to LPA Maturity
The data does offer a clear path forward. Organizations that transition to digital audit systems demonstrate improved overall completion rates within a two-year window, and the proportion of underperforming companies declines meaningfully over that period. This suggests that technology adoption, when paired with strong leadership engagement and process discipline, can meaningfully close the execution gap the report identifies.
The Ease.io LPA Benchmark Report makes clear that audit program success is not simply a function of completing audits. It requires on-time execution, genuine engagement from frontline workers, active participation from plant leadership, and the right digital infrastructure to support it all. For manufacturers under pressure to meet OEM compliance requirements, the accountability and execution gaps revealed in this report represent both a significant risk and a solvable problem.
