c.      provide policies and procedures developed and implemented with the primary focus to assure the continual compliance of the requirements of the International Standard ISO 9001:2015 and AS9100D.

 We set standards for our vendors to remain on our active vendor list.  The criteria is based on the type of service and whether or not it meets the criteria required by the customer. 

 We also strive to effectively train, communicate, and adequately utilize our staff to each member’s capabilities.
