You Cannot Monitor What You Have Not Defined
Scope definition is where many compliance monitoring systems quietly fail before a single audit is conducted. It is also an area where organisations frequently challenge inspection findings, because the weakness is structural rather than procedural, and correcting it often requires redesigning the system itself.
The intent of ORO.GEN.200 and its associated AMC is clear: the compliance monitoring function must cover all activities conducted under the AOC. This includes not only operational departments and in-house functions, but also outsourced activities with regulatory relevance performed on behalf of the operator, such as ground handling, line maintenance, or externally delivered crew training.
The practical starting point is straightforward. List every regulated activity conducted by the organisation or contracted to external providers. Against each activity, identify the applicable regulatory requirement and the internal standard or procedure used to demonstrate compliance. If the applicable requirement cannot be identified, conformance cannot be effectively verified. If the activity is absent from the audit programme, it is not being actively monitored.
Assumptions do not satisfy ORO.GEN.200. Neither does reliance on a supplier’s ISO certification or a copy of its internal audit schedule. Where an outsourced activity results in a non-conformance, accountability remains with the certificate holder.
Take away: Monitoring scope must be explicit, documented, and include all outsourced activities with regulatory relevance. Activities that are not clearly defined cannot be effectively monitored, and weaknesses outside the monitoring scope are unlikely to be identified before they become findings during oversight.
