"Audits are conducted by reputable third-party auditors, typically every 12 to 24 months. Several factors, including the results of the previous audit, dictate audit frequency. Audits are usually scheduled in advance with the suppliers, in order to foster a relationship of trust and cooperation, but unannounced audits are also conducted."
