Audits designed to understand risk

Factory audits provided by third parties often differ in terms of their aim, scope and auditing techniques. PI Berlin focuses on audits designed to assess risk for the buyer or investor – a process which doesn’t just assess the manufacturers’ compliance to their own quality standards, but also evaluates risks in the standards themselves. This ensures that all manufacturers are held to the same high standard and results can be bench-marked across manu- facturers.

A PI Berlin factory audit typically consists of the following major components:

■ Certification compliance

■ Bill of material (BOM) controls

■ Incoming quality controls (IQC)

■ In-line process and quality controls (IPQC)

■ Outgoing quality controls (OQC)

■ Equipment maintenance and calibration

■ Supplier, quality, product and engineering change management

■ Human resource management
