Your company has a Google Workspace account and Google Cloud Organization. The organization has various teams, including developers who need to create and manage Google Cloud projects. However, some developers have created projects outside of the official Google Cloud Organization, leading to issues with policy management and control. You want to establish an Organization structure that allows developers the flexibility to create projects but ensures they cannot modify production projects.

This structure should also minimize disruption to users and developers when there are changes in business needs.
