Layered Process Audits (LPAs) are structured evaluations that span multiple organizational levels to ensure adherence to established processes and enhance performance [10]. They involve observations and interviews with employees to define standards and identify improvement opportunities, conducted by trained auditors from different departments, not just Quality [5]. Key elements include:
Daily audits by shop floor supervisors
Weekly audits by middle management
Monthly/quarterly audits by plant managers and executives [7]
The goal is to consistently follow procedures, maintain quality standards, rectify deviations promptly, and drive continuous improvement [8]. LPAs help instill a culture of quality as senior managers demonstrate its importance.
Implementing an effective Layered Process Audit (LPA) program involves a systematic approach and adherence to industry best practices [9]. The key steps include:

Additionally, senior management support, clear communication, and ensuring the audits have a genuine impact are crucial for the program's success [4].
