AS9100 Internal Audit Procedure

When auditing an aerospace business process it is important to determine how much process planning has gone into the creation of the process and the system of processes that it belongs to. Many aircraft manufacturers appear to combine their business processes together with little systems planning, that it is no wonder why it is hard to achieve planned results.

Business process planning means that each element of the process has been determined. As an AS9100 auditor, we want to understand how much the process participants (employees) understand about their process. The AS9100 Internal Audit Procedure describes the company’s Internal Audit process. The procedure applies to all operations affecting or affected by the company’s QMS. (8 pages, 2479 words)
