Layered Process Audits (LPA) are structured audits conducted across multiple organizational levels to ensure process compliance. In an LPA system, auditors at different management levels use role-specific checklists to assess workplace areas and standards. Unlike traditional quality inspections, which often examine the finished product, LPAs are proactive: they verify that the processes used to create the product are being followed correctly. The approach emphasizes adherence to standardized work rather than merely finding errors. This helps organizations identify deviations early, reduce defects and rework, and foster a culture of continuous improvement.
