Layered Process Audit (LPA)

Layered Process Audits (LPA) are a form of internal audits that focus on the critical manufacturing process. Audits can be performed by multiple levels of organization personnel, including top management. Users can define layers, frequency, duration, how many auditors are involved, whether they need an approver, and create the checklist defining machines and production lines. LPA is a cultural change that drives importance from board rooms to shop floors, each layer implies the importance of the activities done on each shop floor. There are four critical elements that comprise LPA:

• LPA provides insights from the verification of compliance to documented manufacturing/assembly processes.
• You can ensure leadership involvement, as various levels of management will verify quality audits by operators.
• Audits can be conducted at varying frequencies, based on the level of management.
• LPA can continually improve quality and ultimately reduce defect rates.
