By selecting a predefined role specifically designed for BigQuery, the new team member will gain the permissions necessary to perform their job without being granted excessive permissions that could arise from using a more general or broader primitive role. This not only efficiently grants the required access but also minimizes security risks by ensuring that the user operates within clearly defined capabilities.

Predefined roles are maintained and updated by Google, ensuring that they evolve with the service and any associated best practices for security. This automatic updating means that when a new feature is integrated into BigQuery, the predefined roles can be adjusted accordingly, reducing the administrative burden of constantly managing custom permissions.

In contrast, a custom role would require a deeper understanding of the specific permissions necessary for the user’s role, which could lead to potential misconfigurations or oversight. Primitive roles, which are very broad in nature, can expose resources unnecessarily. Managed roles, as a conceptual term, vary and may not directly
