Evaluate the different relationships between the KPA’s from a Compliance and Legislation standpoint. Which KPA’s have the most important dependencies?

Documentation is a fundamental KPA for compliance; it’s a means of demonstrating past and present compliance with laws/regulations/restrictions.
The Asset ID KPA is also important; without it the documentation will be incomplete. The asset ID is the means to track the asset, ensuring it is in the right region, traceable when conducting an internal audit, etc.
