In aviation we have procedures for just about every activity. As we understand procedures are connected to policies as well as the need to demonstrate regulatory compliance.
 
Procedures belong within the QC environment but facilitate the functioning of the QA process. Without procedures auditing becomes very challenging (Ultimately it is the business area owner or post holder/nominated person (NP) who has the ultimate responsibility for the integrity of the procedure).

In our PART M - CAR M / Part 145 – CAR 145 environment we have the Continuous Airworthiness Management Exposition (CAME) and the Maintenance Organization Exposition (MOE) Procedures as well as a myriad of other documents.
