8.6 Internal Systems Audits (ISO 19011)

While LPAs check the floor execution, Internal Audits verify the management system against the ISO standard.

• Independence: Auditors cannot audit their own department. Engineering audits Purchasing; Purchasing audits HR. This ensures objectivity.
• Evidence-Based: Findings must be supported by Objective Evidence (samples, records, observations). "I think" is not a valid audit finding.
• The Audit Schedule: Audits must be scheduled based on risk. Critical areas (SMT Reflow, IQC) are audited more frequently than low-risk areas (Training Records).
