With most endeavors the amount of detail and forethought you devote to your preparations, the better your final result, and layered process audits (LPAs) are no exception. One of the most significant tasks of implementing an LPA system is writing the questions for your LPA checklists. Spending time upfront to investigate what has gone wrong in the past with your processes provides valuable insight for preparing an audit checklist that covers all the bases to satisfy your customers and promote a culture of quality throughout your organization.
