LPA (Layered Process Audit)
Layered Process Audit
Frequent short process audits performed by different management levels to verify critical standards and controls.
Examples
- 01In the LPA schedule, team leaders check torque settings daily, supervisors weekly and the plant manager monthly.
- 02LPA results are reviewed every week, and repeated 'no' answers on one question point to a weak standard.
- 03When an LPA finds the error-proofing switched off, the station is stopped immediately and the last hour of production is checked.
