The AS9100 implementation process goes through a few simple steps. First get management support, identify your requirements and scope and define and implement all your processes. Next rain everyone to the level needed and choose a certification body that will benefit your company. Operate your system to collect records, perform internal audit and management review to identify and corrections or improvements needed, and put in place corrective actions. Finally, the certification auditors will conduct a stage 1 documentation audit and a stage 2 certification audit where they will review all your processes against the AS9100 standard and your internal and customer requirements.
